Why Visit Yilan Guishan Island?

Guishan Island is worth visiting because it gives travellers a very different view of Taiwan. Instead of temples, night markets or city streets, you get open sea, volcanic cliffs, marine wildlife, sulphur-tinged waters and dramatic views back toward the Yilan coast.

The island is especially memorable because it feels wild and protected. Visitor access is limited, and many people only see the island from the mainland or from a boat. A tour around Guishan Island lets you appreciate its unusual shape, rugged coastline and importance as a landmark of Yilan.

Guishan Island is best for:

• Travellers interested in Taiwan’s volcanic landscapes
• Whale and dolphin watching trips from Yilan
• Nature lovers looking for a half-day coastal experience
• Photographers wanting sea cliffs, blue water and island silhouettes
• Visitors staying in Toucheng, Jiaoxi, Yilan or Taipei
• Families who enjoy boat trips, if sea conditions are suitable
• Travellers combining Yilan hot springs, beaches and coastal scenery

Where Is Guishan Island?

Guishan Island sits off the coast of Toucheng Township in Yilan County, north-eastern Taiwan. It is easily seen from coastal viewpoints around Toucheng, Wai’ao, Daxi and the Yilan coast on clear days.

Most travellers do not travel independently to the island. Instead, they book a licensed boat tour or package that handles boat transport, landing arrangements where applicable and safety requirements.

What to Expect on a Guishan Island Trip

Expect a sea-based nature trip rather than a relaxed beach resort day. Tours usually depart from Wushi Harbor and head toward the island by boat. Depending on the package, sea conditions and permits, the trip may include whale and dolphin watching, a cruise around the island, views of the Milk Sea and a landing on Guishan Island.

The experience is weather-dependent. Trips may be cancelled or changed if wind, waves or visibility make conditions unsafe. Seasickness can be a real issue for some travellers, especially when the Pacific is choppy.

What you may experience

• Boat ride from Wushi Harbor
• Views of Guishan Island’s turtle-shaped profile
• Whale and dolphin watching, depending on season and luck
• Milk Sea turquoise water near volcanic vents
• Sea cliffs, caves and rugged coastline views
• Controlled island landing if included and approved
• Walking paths, lake views and old settlement traces on the island
• Optional hiking routes on some tours
• Strong sun, wind and sea spray

What not to expect

• Do not expect to visit the island without advance arrangements.
• Do not expect whale or dolphin sightings to be guaranteed.
• Do not expect calm water every day.
• Do not expect restaurants, shops or resort-style facilities on the island.
• Do not expect every tour to include landing.
• Do not assume summit hiking is included in a standard boat tour.

Main Guishan Island Experiences

Whale and Dolphin Watching Around Guishan Island

Guishan Island is one of Taiwan’s best-known whale and dolphin watching areas. Boat tours from Wushi Harbor search the surrounding waters for marine wildlife, especially during the warmer months when conditions are more favourable.

Commonly promoted sightings include dolphins, and some trips may also encounter whales depending on season, sea conditions and luck. Because these are wild animals, no ethical operator should guarantee sightings.

Whale and dolphin watching tips

• Choose a reputable licensed operator.
• Book during the main promoted season if marine wildlife is a priority.
• Go with realistic expectations; sightings are never guaranteed.
• Take seasickness medication if you are prone to motion sickness.
• Use a camera strap or waterproof phone pouch.
• Listen to crew instructions when wildlife appears.
• Do not throw food, plastic or rubbish into the sea.
• Choose operators that respect safe distances from animals.

Morning trips may offer calmer conditions on some days, but weather and sea state matter more than the clock. Check local forecasts and operator guidance before departure.

The Milk Sea Phenomenon

The Milk Sea is one of Guishan Island’s most striking sights. Near parts of the island, volcanic activity and underwater hot spring vents can mix mineral-rich water with seawater, creating pale turquoise, blue-white or milky-coloured patches against the darker Pacific Ocean.

The colour is best seen in good weather and clear light. On cloudy, rough or low-visibility days, the effect may be less dramatic. Boat tours often include Milk Sea viewing when conditions allow.

How to enjoy the Milk Sea responsibly

• View it from the boat unless your guide says otherwise.
• Do not swim in restricted or unsafe volcanic water areas.
• Do not throw anything into the sea.
• Photograph from a stable position on the boat.
• Expect colours to vary by light, water movement and weather.

Landing on Guishan Island

Landing on Guishan Island is more restricted than taking a boat around it. The island is protected, and visitor numbers are controlled. Travellers who want to step ashore usually need to book through an authorised tour operator or apply in advance through the relevant scenic area system.

Landing tours may include walking paths, Guiwei Lake, old settlement areas, military-era traces, coastal scenery and views across the island’s volcanic landscape. Some tours may include more demanding hiking, but this should be checked carefully before booking.

Before booking a landing tour, check:

• Whether landing is actually included
• Whether the operator handles permit application
• Whether passport or ID details are needed in advance
• Whether the trip includes whale watching or only island landing
• Whether hiking to higher viewpoints is included
• Fitness requirements and number of stairs
• Whether children or older travellers can join comfortably
• Bad-weather cancellation and refund policy

If you only book a whale watching or Milk Sea cruise, you may not land on the island. Read the product details closely.

Yilan Guishan Island Travel Tips

Book ahead

Landing numbers are controlled and boat departures can fill during the main season. Book early if you want a specific date or landing tour.

Check whether landing is included

Some tours only circle the island or do whale watching. Others include landing. Read the booking details carefully before paying.

Bring ID or passport details

Permit-backed tours may require identification details in advance. International travellers should carry a passport or a copy as advised by the operator.

Prepare for seasickness

The sea around Guishan Island can be choppy. If you are prone to motion sickness, take suitable precautions before boarding.

Wear sun protection

Bring sunscreen, sunglasses, hat and lightweight long sleeves. Sun exposure is strong on the water.

Use secure footwear

If landing or walking on the island, wear comfortable shoes with grip. Avoid slippery sandals.

Pack light but smart

Bring water, snacks, rain jacket, dry bag, camera strap and any medication you need. Facilities on the island are limited.

Listen to the crew

Boat captains and guides know local sea conditions. Follow their instructions, especially when boarding, wildlife appears or waves increase.

Keep your itinerary flexible

Boat tours can be delayed or cancelled by weather. Do not schedule a tight train, flight or important booking immediately after the tour.

Respect the protected environment

Do not leave rubbish, take rocks, disturb wildlife, enter restricted areas or damage volcanic and coastal features.

Is Yilan Guishan Island Worth Visiting?

Yes, Yilan Guishan Island is worth visiting if you enjoy volcanic landscapes, boat trips, marine wildlife, dramatic coastal scenery and nature-based experiences. It is one of Taiwan’s most recognisable offshore landmarks and a strong addition to a Yilan or Taipei itinerary.
