Blue Cave and Žanjice Beach, Montenegro: A Practical Boat-Trip Guide

A boat trip to Montenegro Blue Cave and Žanjice Beach combines one of the country’s most photographed natural attractions with a relaxed swimming stop on the Luštica Peninsula.

The Blue Cave, known locally as Plava Špilja, is a sea grotto cut into the rocky Adriatic coast. When sunlight enters through its openings and reflects from the pale seabed, the water and cave walls take on an intense blue glow.

Žanjice Beach lies nearby in a protected bay facing the entrance to the Bay of Kotor. Its clear water, white pebbles, olive trees and waterfront restaurants make it a practical place to spend several hours after visiting the cave.

The two destinations are commonly combined on boat trips from Herceg Novi, Igalo, Kotor and Tivat. However, the experience differs greatly according to the departure point. A short boat from Herceg Novi may focus on swimming and beach time, while a longer speedboat from Kotor may add Our Lady of the Rocks, Mamula Island and former submarine tunnels.

This guide explains how the tours work, what the cave really looks like, when the blue light is strongest, what to expect at Žanjice Beach and how to choose the right itinerary.

Blue Cave and Žanjice Quick Facts

Important: Cave entry and swimming are never guaranteed. Wind, swell, boat congestion and the skipper’s safety assessment determine whether a vessel can enter.

Where Are the Blue Cave and Žanjice Beach?

Both destinations lie on the Luštica Peninsula, the long mountainous peninsula forming the southern side of the outer Bay of Kotor.

Žanjice Beach faces north and west towards the bay entrance. It is sheltered by Cape Arza and is relatively calm compared with the exposed Adriatic coast.

The Blue Cave lies farther around the peninsula on the open-sea side, between Zlatna Luka Cove and Cape Mokra Gora.

Although they are close by boat, they face different conditions:

• Žanjice: Sheltered bay, beach facilities and relatively calm swimming.
• Blue Cave: Exposed rocky Adriatic coast, deeper water and weather-dependent access.

Why Combine Them in One Trip?

A visit to the cave itself may last only 10 to 30 minutes. Combining it with Žanjice turns a short sightseeing stop into a more complete coastal day.

The cave provides:

• Dramatic limestone scenery.
• Bright blue reflected light.
• A possible swim inside a sea grotto.
• A memorable boat journey along Luštica.

Žanjice adds:

• A long swimming break.
• Restaurants and refreshments.
• Sunbeds and beach facilities.
• Clear water suitable for snorkelling.
• Views towards Mamula and the bay entrance.

The combination is particularly suitable for travellers who want sightseeing and swimming without committing to a full-day open-sea cruise.

What Is the Blue Cave?

The Blue Cave is a natural marine grotto formed beneath cliffs rising approximately 30 metres above the Adriatic.

It has two principal sea entrances:

• A larger opening used by small tour boats.
• A smaller opening through which sunlight helps illuminate the interior.

The interior is roughly circular, with a vaulted stone ceiling. Small boats can enter when sea conditions permit.

The cave is a natural formation rather than a developed attraction. There are no platforms, lights, changing rooms or permanent staff inside.

Visitors remain in the boat or enter directly into deep seawater.

Why Does the Water Look Blue?

The colour is created by sunlight passing through the water and reflecting from the pale seabed.

The reflected light travels upward and illuminates the water, cave walls and the underside of boats and swimmers.

The exact appearance changes according to:

• Time of day.
• Sun angle.
• Cloud cover.
• Water clarity.
• Wave movement.
• The number of boats inside.

On a bright, calm morning, the water can appear intensely electric blue. On an overcast afternoon, it may look darker and more green-grey.

Promotional photographs often show the cave under ideal conditions. The natural light is impressive, but it is not equally strong every day.

The Best Time to See the Blue Colour

Morning generally provides the strongest illumination.

Official regional information notes that the effect is particularly noticeable on sunny summer mornings, when light reflects through the smaller opening and across the cave interior.

Early Morning

Early departures have several advantages:

• Fewer boats.
• Calmer sea on many days.
• Cooler temperatures.
• Better chance of entering before congestion develops.

The blue effect may still be developing shortly after sunrise, depending on the season.

Mid-Morning

Mid-morning usually provides the best balance between strong light and manageable crowds.

Afternoon

The cave remains worth seeing, but the reflected colour may be weaker. Afternoon wind and swell can also increase.

Sunset Tours

Sunset boat trips can be beautiful along the coastline, but they are not the best choice when the glowing blue cave is the main priority.

What Happens Inside the Cave?

When conditions are calm, the skipper slows the boat and approaches the larger cave entrance.

The opening can appear low from the water, although the interior ceiling rises considerably once inside.

Passengers usually remain seated while the boat enters. Depending on the vessel and traffic, the skipper may:

• Make a slow circuit inside.
• Pause for photographs.
• Allow swimming.
• Exit through the same opening.
• Wait outside while passengers swim in.

The visit can feel peaceful on a quiet morning. During peak summer periods, several boats may enter or wait outside at the same time.

Engine noise, music and crowds can reduce the natural atmosphere. Choosing an early tour or private boat usually improves the experience.

Swimming in the Blue Cave

Swimming is one of the cave’s main attractions, but it is not suitable for everyone.

The water is several metres deep, and there is no beach, platform or shallow standing area.

Ways the Swim May Work

• The boat enters and passengers climb down a ladder.
• The boat stops outside and confident swimmers enter through the cave opening.
• The skipper permits only a short swim beside the vessel.
• Swimming is cancelled because of waves or boat congestion.

You Should Be Comfortable With

• Deep water.
• Climbing a boat ladder.
• Swimming near other vessels.
• Cooler shaded water.
• Movement caused by waves.

Wear a life jacket or buoyancy aid when you are not a strong swimmer.

Do not jump from cliffs or the boat unless the crew specifically authorises it and confirms that the water below is safe.

What Is Žanjice Beach Like?

Žanjice is a broad pebble beach in a protected cove on the western side of Luštica.

White and pale-grey stones continue beneath clear water, creating attractive blue and turquoise colours.

The beach is backed by olive trees, low vegetation, restaurants and small accommodation properties.

Beach Surface

Žanjice is not a soft-sand beach.

The pebbles can be uncomfortable under bare feet and become hot during summer. Water shoes make entering and leaving the sea much easier.

Water Conditions

The bay is usually calmer than the open coast, but passing boats can create wake.

The water becomes deep relatively quickly in some sections. Families should choose their position carefully and supervise children.

Water Clarity

Visibility is often excellent, especially in the morning before increased boat traffic disturbs the water.

A simple mask and snorkel can reveal:

• Small fish.
• Rocky seabed.
• Sea urchins.
• Occasional starfish or other marine life.

Avoid standing on or touching sea urchins and other animals.

Beach Facilities and Restaurants

Žanjice has considerably more visitor infrastructure than the Blue Cave.

Seasonal facilities commonly include:

• Waterfront restaurants.
• Cafés and bars.
• Sunbed and umbrella rental.
• Boat-ticket sellers.
• Small jetties.
• Toilets linked to restaurants or beach businesses.
• Simple accommodation.
• Kayak or small-boat services in some seasons.

Services operate most reliably from late spring through early autumn.

Outside the main season, restaurants may close or use reduced hours.

Food

Menus often focus on:

• Fresh fish.
• Grilled squid.
• Mussels.
• Salads.
• Pasta and risotto.
• Grilled meat.
• Pizza and simple snacks.

Waterfront restaurant prices can be higher than in inland villages. Check the menu before ordering fish sold by weight.

Sunbeds

Prices vary by operator, date and row. Some sections remain available for visitors using their own towels.

Do not assume that a tour ticket includes a sunbed.

How to Get to the Blue Cave and Žanjice Beach

The Blue Cave is reached from the sea. Žanjice can be reached by boat or road.

The most convenient departure depends on where you are staying.

Tours from Herceg Novi and Igalo

Herceg Novi is the closest major tourist town and one of the best bases for this trip.

Seasonal boats leave from:

• Škver harbour in Herceg Novi.
• Igalo waterfront.
• Other small stops along the Herceg Novi Riviera.

Options include:

• Direct sightseeing speedboats.
• Full-day beach boats.
• Private charters.
• Boat transfers to Žanjice with a separate cave excursion.

Full-Day Beach Boats

Some larger boats depart in the morning or around midday and provide several hours at Žanjice.

The cave visit may be included in the ticket or arranged using a smaller local boat after reaching the beach.

Before buying, ask:

• Is Blue Cave admission included?
• How long is the beach stop?
• Is swimming inside the cave planned?
• Which boat returns to Herceg Novi?
• What happens if the cave is inaccessible?

Short Speedboat Tours

Speedboats can visit Mamula, the cave and Žanjice in approximately two to three hours.

This is suitable for travellers who do not want a full beach day.

Tours from Kotor

Kotor tours travel through almost the entire Bay of Kotor before reaching the open Adriatic.

The journey can include:

• Perast.
• Our Lady of the Rocks.
• Verige Strait.
• Tivat Bay.
• Former submarine tunnels.
• Mamula Island.
• The Blue Cave.
• Žanjice Beach.

Three-Hour Tour

A three-hour tour is fast-paced. It normally allows only a short cave visit and may pass Žanjice without a substantial beach stop.

Four- to Six-Hour Tour

This is a better choice when you want time to swim and relax at Žanjice.

Full-Day Cruise

Longer catamaran and group cruises may provide meals, drinks and several swimming stops.

They are less flexible than a small private boat but can be more comfortable for passengers who dislike speedboat impacts.

Tours from Tivat

Tivat lies closer to the outer bay than Kotor and offers numerous marina-based boat trips.

Tours may depart from:

• Tivat waterfront.
• Porto Montenegro.
• Nearby marinas and pontoons.

Three-hour speedboat routes commonly include the cave, Mamula and a submarine tunnel.

Longer excursions may include Žanjice swimming time or Our Lady of the Rocks.

Reaching Žanjice by Car

Žanjice is connected by road through the Luštica Peninsula.

Driving provides flexibility and allows visitors to take a short local boat from the beach to the cave.

What the Drive Is Like

The peninsula has narrow, winding roads with limited passing space in some areas.

Expect:

• Sharp bends.
• Steep sections.
• Local traffic.
• Limited roadside barriers.
• Slow travel during summer.
• Parking congestion near beaches.

Drive carefully and avoid following a navigation route that appears to use an unsuitable unsealed shortcut.

Parking

Parking is available near the beach, but it can fill on July and August weekends.

Arrive early and keep valuables out of sight.

Local Boats to the Cave

Boat operators at Žanjice commonly offer short return trips to the cave during the summer season.

Confirm the price, total duration and swimming time before boarding.

Choosing the Right Boat Tour

Short Shared Cave Tour

Best for travellers who mainly want to see the cave.

Advantages:

• Lower cost.
• Short duration.
• Frequent summer availability.

Limitations:

• Little or no beach time.
• Crowded boat.
• Fixed route.

Blue Cave and Žanjice Tour

Best for swimming and a relaxed half-day.

Look for a route that specifically names Žanjice and states the duration of the free-time stop.

Bay of Kotor Highlights Tour

Best for first-time visitors staying in Kotor or Tivat.

The day combines natural and historical attractions but may feel rushed.

Private Speedboat

Best for couples, families and small groups wanting flexibility.

Advantages may include:

• Earlier departure.
• Longer swim.
• Ability to skip unwanted stops.
• More space.
• Hotel or nearby jetty pickup.

Confirm whether fuel, skipper, drinks, towels and dock fees are included.

Large Group Boat

Best for travellers seeking a slower and less expensive full-day trip.

Large boats may be unable to enter the Blue Cave. Passengers may transfer to a smaller vessel or view the entrance from outside.

Typical Tour Prices

Prices change by season and operator, but current listings provide a general guide.

These are examples rather than fixed official tariffs.

Check whether the price includes:

• Fuel.
• Skipper.
• Drinking water.
• Snorkelling equipment.
• Beach stop.
• Insurance.
• Pickup.
• Taxes and booking fees.

Typical Blue Cave and Žanjice Itinerary

Departure

Meet the crew at the harbour, complete check-in and receive safety instructions.

Cruise Towards Luštica

The boat passes the outer Bay of Kotor, coastal villages and mountainous scenery.

Mamula Island

Many tours slow for photographs of the circular fortress.

Blue Cave

The skipper enters when conditions permit. Passengers take photographs and may swim.

Žanjice Beach

The boat docks or anchors near the beach. Free time may range from 30 minutes to several hours.

Optional Additional Stops

Depending on the tour:

• Former submarine tunnel.
• Mirište Cove.
• Rose village.
• Our Lady of the Rocks.
• Perast.

Return

The boat returns through the bay, often during stronger afternoon wind.

Mamula Island

Mamula, officially Lastavica Island, stands at the entrance to the Bay of Kotor.

The circular stone fortress was built during the Austro-Hungarian period to control access to the bay.

The island also has a difficult 20th-century history, including use as a detention camp during the Second World War.

It has since been redeveloped as a private luxury hotel. Most sightseeing boats provide only a panoramic view unless a specific authorised visit is included.

Do not assume you can step ashore simply because the boat passes close to the island.

Former Submarine Tunnels

Several military tunnels were cut into the Luštica coastline during the Yugoslav period.

They were designed to hide naval vessels and equipment inside the rock.

Speedboat tours often enter one tunnel briefly or stop at its entrance.

The visit provides a striking contrast with the natural cave:

• The Blue Cave was formed by sea erosion.
• The submarine tunnels were engineered for military use.

Access depends on local restrictions and boat traffic.

Mirište Cove and Arza Fortress

Mirište lies close to Žanjice and offers another attractive swimming area with rocky platforms, clear water and Mediterranean vegetation.

From the coast, visitors can see the small island church often called Mala Gospa and the nearby Arza Fortress.

Some boat tours use Mirište instead of Žanjice for a swimming or lunch stop.

Check the itinerary carefully if a particular beach matters to you.

Sea Conditions and Cancellations

The Blue Cave faces the open Adriatic and is more exposed than the inner Bay of Kotor.

Conditions can be calm inside the bay but rough near the cave.

The Skipper May

• Delay departure.
• Change the order of stops.
• Skip the cave.
• Allow viewing from outside only.
• Cancel swimming.
• Use a more sheltered beach.
• Cancel the entire trip.

Wind

Afternoon wind can create a choppier return journey, especially in a small speedboat.

Rain

Light rain may not stop the excursion, but thunderstorms and poor visibility can make the open coast unsafe.

Motion Sickness

Visitors prone to seasickness should:

• Book a morning departure.
• Choose a larger boat.
• Sit near the centre or rear.
• Look at the horizon.
• Avoid a heavy meal.
• Use appropriate medication when medically suitable.

The Best Season and Time of Day

May and June

These months offer warm weather, moderate crowds and good water clarity.

The sea can still feel cool in May.

July and August

This is the busiest period. Boats may queue outside the cave, and Žanjice can become crowded.

Reserve early and choose the first departure of the day.

September

September is often ideal, with warm sea temperatures and fewer visitors.

October

Early October can remain pleasant, but operators reduce schedules and weather becomes less predictable.

Best Time of Day

A morning tour is best for:

• The blue light.
• Calmer sea.
• Fewer boats.
• Cooler temperatures.
• Better beach space.

Visiting with Children

The combined trip can be suitable for families, particularly when the boat is covered and the itinerary includes a long beach stop.

Before Booking, Confirm

• Minimum child age.
• Availability of child-sized life jackets.
• Shade on board.
• Toilet availability.
• Length of high-speed sections.
• Whether a pushchair can be stored.
• Whether the child must be able to swim.

Young children may find a fast speedboat uncomfortable on choppy water.

At Žanjice, water shoes and close supervision are important because of the pebbles, deepening water and boat traffic near jetties.

Accessibility and Mobility

Small-boat excursions can be difficult for travellers with reduced mobility.

Boarding may involve:

• Steps down to a jetty.
• A moving boat beside the dock.
• A large step into a low vessel.
• Narrow seating.
• Limited handrails.

Žanjice itself has pebbles and uneven surfaces. Ordinary wheelchairs are difficult to move across the beach.

Larger vessels may be easier, but they may not enter the cave.

Ask the operator for a precise description of boarding and beach access before paying.

What to Bring

• Swimwear: Wear it before boarding when changing facilities are limited.
• Towel: Bring a quick-drying towel.
• Water shoes: Highly recommended for Žanjice’s pebbles.
• Sunscreen: Reflected sunlight is strong on the water.
• Secure hat: Avoid loose hats on a speedboat.
• Sunglasses: Polarised lenses help with glare.
• Drinking water: Confirm whether the boat provides it.
• Light layer: Useful on windy returns.
• Waterproof phone pouch: Protects electronics from spray.
• Small dry bag: Keeps clothes and valuables dry.
• Snorkelling mask: Bring your own when snorkelling matters.
• Cash: Useful for restaurants, sunbeds and local boats.

Avoid large suitcases and unnecessary bags.

Photography Tips

Inside the Cave

• Use a wide-angle setting.
• Turn off the flash.
• Use low-light or night mode.
• Include the entrance for scale.
• Take several images because the boat moves.
• Protect the camera from spray.

Underwater Photographs

A waterproof action camera can capture the blue glow beneath the surface.

Attach it securely rather than holding it loosely while swimming.

At Žanjice

The best views often come from:

• The arrival boat.
• The ends of the beach.
• Restaurant terraces.
• The path towards Mirište.

Morning light generally gives the clearest water colour.

Responsible Visiting

The cave and Luštica coast are natural environments affected by heavy seasonal boat traffic.

• Do not throw rubbish into the water.
• Do not touch or break cave formations.
• Do not carve names into rock.
• Do not remove stones, shells or marine animals.
• Avoid standing on sea urchins or living seabed.
• Use reef-conscious sunscreen where possible.
• Keep noise moderate inside the cave.
• Follow the skipper’s instructions.
• Do not pressure the crew to enter during unsafe conditions.
• Use recognised jetties and swimming areas.

The cave’s popularity is placing increasing pressure on a small natural space. An early small-group tour usually creates less congestion than arriving at midday with multiple large vessels.

Final Thoughts

The Blue Cave and Žanjice Beach provide one of the best combinations of natural sightseeing and relaxed swimming around the Bay of Kotor.

The cave is small enough to feel intimate but large enough for boats to enter when the sea is calm. Its famous colour is a natural light effect rather than artificial illumination, which means every visit looks slightly different.

Žanjice balances the short cave experience with clear water, restaurants and enough space to spend several hours beside the sea.

For the best trip, choose a sunny morning, confirm how much beach time is included and avoid treating cave entry as guaranteed. Bring water shoes, sun protection and a waterproof phone case, and accept that the skipper may alter the route when the open Adriatic becomes rough.

With suitable conditions and a responsible operator, the glowing cave, rocky Luštica coast and calm bay at Žanjice make this one of Montenegro’s most memorable boat excursions.
