Guishan Island Marine Protected Area surrounds Taiwan’s only volcanic island, offering rich marine biodiversity and unique geological formations for eco-tourists and marine enthusiasts.
Guishan Island Marine Protected Area encircles Guishan Island, a volcanic island located off the northeastern coast of Taiwan, approximately 9 km east of Yilan County. Known also as Turtle Island for its turtle-like shape, this marine protected area preserves a unique volcanic landscape both above and below the water. The island’s volcanic cones, caves, and underwater hydrothermal vents sustain a high level of marine biodiversity, including coral reefs, colorful fish species, and migratory cetaceans such as humpback whales and dolphins. Ecologically significant, the area provides critical habitat for numerous rare and protected species. Historically, Guishan Island has served as a fishing and whaling ground, but today, it is a focal point for conservation and sustainable tourism. Visitors can participate in guided boat tours, snorkeling, diving, and whale watching. The island itself is accessible by ferry from Toucheng Township, and it features hiking trails that reveal volcanic craters, sulfur vents, and scenic overlooks across the Pacific Ocean. Its designation as a Marine Protected Area ensures ongoing efforts to maintain water quality, protect marine life, and promote environmental education. The MPA appeals to nature lovers, researchers, and outdoor adventurers aiming to experience a rare volcanic marine ecosystem with abundant wildlife and pristine waters. The combination of geological wonders, spectacular underwater sceneries, and seasonal marine mammal sightings makes Guishan Island Marine Protected Area a must-visit destination on Taiwan’s northeastern coast.
