Summary: On a two-hour boat trip out of Wushih Harbour (19 May 2026) and around Guishan Island we saw Common Bottlenose Dolphin and Spinner Dolphin. iNaturalist (June 2026) shows records of 12 species of cetaceans in off Toucheng, including some interesting species such as both species of Kogia.

C. Trip and Site Information
I was joined on this trip by Chi Phan.
Wushih Harbour is on the northern side of Toucheng township on the northeast coast of Taiwan. It is 50 km southeast of Taipei city. Whale-watching operations from Wushi are generally done from April to October. There are a number of whale-watching operators and we used JIN36 (Xin Fufeng No. 36), based on online reviews.
Our trip went out to Guishan Island (Turtle Island), 10 km southeast of Wushih Harbour, and from there we did a circuit around the island before heading back to Wushih. The trip cost NT$ 900 each (about US$28). We left the harbour at 10:30 AM and returned at 12:45. There are longer trip options that include walks on the island. In 2010 a colony of Ryuku Flying-fox was discovered on the island.
A few days after this trip I did four whale-watching trips off Hualien where I saw six cetaceans including Spinner Dolphin but not Common Dolphin.
