Dive-site story
Located off the southern coast of Penghu's main island, Hangwan features shallow coral beds and an active community-led reef restoration zone. Divers navigate between patches of branching stony coral and artificial structures, including a functioning underwater mailbox where waterproof postcards can be sent. The sheltered bay provides calm training conditions during the summer season, with sandy paths winding among sea anemone clusters and rocky substrate.
Submerged operational mailbox that serves as an artificial reef habitat
Active coral restoration nursery featuring transplanted branching Acropora colonies
Dense anemone fields inhabited by resident clownfish pairs
Easy navigation across shallow sandy channels and low-profile rocky outcroppings
Location
Use the map to plan with your operator and confirm the exact entry point on the day.
Seasonality
The summer window provides manageable seas before the fierce northeast monsoon dominates Penghu in late autumn and winter.
