Swim with Jellyfish

Swim with Jellyfish  
Sometimes, you just need to get away—far, far away. These unique travel destinations will open a new world of exploration and adventure!   Take a trip to the Rock Islands for a cool dip with the golden jellyfish. Located in the Pacific island of Palau, Jellyfish Lake is a completely landlocked saltwater lake that used to have an output to the ocean. Today, the jellyfish that live there feed on algae and have lost their stinging ability, so tourists can enjoy swimming with the creatures up close and personal.

Experience an ice hotel.

Bunk in an Igloo  
From Sweden to Canada to Finland, ice hotels are popping up in locations across the globe. The unique hotels, which melt every year and are rebuilt the next season, offer walls and fixtures made entirely of ice. Most are furnished with amenities like artic sleeping bags, meals prepared over an open fire, reindeer parks and even chapels. The fact that the hotels melt each year means that the architecture of each space is constantly changing.
