Dive-site story
Located off the northeastern tip of Orchid Island (Lanyu), Twin Lion Rock features dramatic underwater volcanic topography shaped by old lava flows. Submerged canyons, swim-throughs, and towering boulders carpeted in sea fans drop away into deep blue oceanic waters swept by the Kuroshio Current.
Rugged volcanic basalt arches and deep coral-encrusted canyons
Frequent encounters with banded sea kraits hunting between reef crevices
Oceanic clarity typical of offshore Pacific currents
Location
Use the map to plan with your operator and confirm the exact entry point on the day.
Seasonality
Calm seas and southwest summer monsoons make the northeastern coast most accessible, whereas winter northeast monsoons generate rough surface conditions.
