Keelung Islet is a volcanic island situated 5 kilometers off the coast of Keelung, Taiwan, characterized by its steep cliffs and a prominent white lighthouse. The island is primarily composed of andesite and features a unique landscape carved by sea erosion and wind. Visitors can access a network of boardwalk trails that lead to the lighthouse and various geological formations. The islet supports diverse endemic plant species, including the Keelung wild lily and wild chrysanthemum. Marine life surrounding the island is significant, often serving as a site for whale and dolphin watching excursions. It remains uninhabited, functioning exclusively as a preserved natural site for tourism and maritime navigation.
The observation platform near the lighthouse offers a panoramic view of the coastline and the surrounding East China Sea.
Bring a hat and sunscreen as there is minimal shade on the exposed island trails.
Wear sturdy, closed-toe walking shoes to navigate the steep wooden staircases safely.
Carry sufficient water as there are no shops or vending machines available on the island.
Do not attempt to hike the unmaintained dirt paths off the boardwalk, as these are unstable and dangerous.
The island is typically accessible from spring through autumn, weather permitting, and may close during winter months or typhoon season.
Stay strictly on the marked boardwalks to protect fragile endemic flora and avoid slipping on steep terrain.
