For this reason, there are a number of diving opportunities at Yalong Bay at price ranges. For example, at my hotel the charge was 560 yen.
For that I got an hour in the water, snorkeling gear, flippers, rock slippers etc plus an individual following me round taking pictures with an underwater camera.
Venture further down the coast, toward the docks area where you will find a greater range of options, more keen pricing and more Chinese.
Here are an example some pictures from the reef.
