Jelly fish lake is unique on the world. Its a lake what got separated of the sea millions of years ago. That's why the jelly fish what live there lost their stingers... You can plan trips with a boat or you go diving and a part of the dive trip is jelly fish lake. After leaving the boat you hike up a mountain and then down again. Mind your steps it could be slippery. In the lake you are only allowed to freedive and snorkel. Don't dive to deep because of poisonous gases. Please be careful and respect the nature and don't kick the jelly fish with your fins. You can touch them and it's amazing to be surrounded by millions of them. If you have an underwater cam you might do a video or some pictures while freediving for a nice memory...
