Turtle Island Whale Watching in Yilan

Part of the Yilan travel guide — see every topic in All Yilan Guides.

Turtle Island, or Guishan Island, is a small volcanic island about 9 kilometres off the Yilan coast. From the shore it looks like a turtle swimming out to sea. The waters around it are rich in fish, so dolphins and sometimes whales come here to feed. Boats leave from Wushi Harbor in Toucheng for whale and dolphin watching trips. Some trips also land on the island itself, but landing needs a permit and numbers are limited each day.

Dolphins and whales

Whale watching boats from Wushi Harbor run from about spring to autumn, roughly March to November. Dolphins are the most common sight. Several kinds live here, and you often see groups swimming and jumping near the boat. Whales are seen less often, so do not expect them on every trip. Most trips last about two hours and circle around Turtle Island, so you also get close views of its cliffs and the volcanic coast. Calm summer mornings are usually best. Operators may cancel trips in strong wind or rough seas, and they often offer a second trip if you see no animals.

The island up close

Turtle Island is about 2.8 square kilometres in area, and its highest point is about 360 metres. It is an active volcanic island. Hot water and gas come out under the sea near the turtle's head, and on some days the water there turns milky white and blue. Boats often pass close by so you can see this. The island has steep green slopes, cliffs and a small lake. In April 2024 a strong earthquake caused rockfalls on the turtle's head, so parts of the island may have changed. Ask your boat operator about the current conditions.

Landing permits and quotas

Landing on Turtle Island is controlled to protect nature. The island is usually open to visitors from about March to November. You must apply in advance through the Northeast and Yilan Coast National Scenic Area office, and the number of visitors each day is limited. Wednesdays have a smaller quota than other days. Most people book through a boat operator, who handles the permit, the boat and the landing time. Climbing to the summit needs a separate permit and has a much smaller limit. Apply early for weekends. Rules and quotas can change, so check the official site before you plan.

Tips for the boat trip

The sea off Yilan can be rough even on sunny days, and boats rock a lot. If you get seasick, take medicine before you leave and stay on the open deck, looking at the horizon. Bring a hat, sun cream, water and a light jacket, because spray and wind are cold on the water. Bring your passport or ID, since it is often checked before boarding. Choose an operator that keeps a respectful distance from the animals and does not chase them. Morning trips usually have calmer seas, so book an early departure if you can.
