Willingly jump into an entire lake filled with jellyfish?!?
A must if you are in Palau.
These particular type of jellyfish do not sting; instead their food source (algae) is cultivated inside their bodies.
Only snorkeling (no SCUBA diving) is permitted in Jellyfish Lake, but the surface is where all the action is. During the day, these jellies drift along the surface to follow the sun. At night, they descend into the nitrogen-rich lake bottom.
Jellyfish Lake is less than an hour away from Koror, Palau. Visitors must obtain a permit to snorkel here; the permit for Jellyfish Lake/Rock Islands is good for 10 days. Rumor has it that permit fees will increase drastically in the fall of 2012... Travel now!
