Jellyfish Lake, Palau - Palau’s Jellyfish Lake once had an outlet to the sea, but is now connected to the ocean through fissures and tunnels in the surrounding limestone. Millions of jellyfish were trapped in the basin when sea levels dropped, and over time they evolved into a species that have lost the ability to sting because they don’t have to fight off predators. You can swim and snorkel here.
As manatees cant survive in water below 60 degrees, they migrate to Kings Bay and the adjacent rivers every winter, which are an average 72 degrees all year round. So from November through March 2012, you can head to Crystal River, which is 70 miles north of Tampa, where it is the epicenter of manatee-watching, and go swim with these giant but affectionate creatures. This looks so fun! I think I would freaakkk out
