Crab boats can stop outside the leaking lake, and you need to swim through a small hole in the sea to enter the leaking lake. Of course, kayak is also a good choice. The water is deep but clear. You can see a lot of fish and even turtles in snorkeling. You can walk in a small boat and feel like you are entering an increasingly quiet green world. The deepest part of the trip is a cave, giving a mysterious feeling.
