Snorkeling in China
Including Chengmai Bay, Dadonghai Beach, and Gulangyu Island. On the map.
The vibe
Snorkeling here is rarely the primary focus of a trip, often feeling like a secondary activity tacked onto a broader coastal excursion. The water clarity varies significantly depending on the region, so it is best to aim for the shoulder seasons when the seas are calmest and visibility is at its peak. Most spots feel quite local or DIY, as you are likely to be exploring off the beaten path rather than joining a structured marine-park tour.
