(CNN) — If you really want to “get away from it all,” there’s only one place for it. Outer space.
But a good second option can be found in the opposite direction — under the sea, with only glass between you and oceans of water.

Jules’ Undersea Lodge, Key Largo, Florida, United States

Museo Subacuatico de Arte (MUSA), Yucatan Peninsula, Mexico
An underwater museum with an eco twist.
This unique installation of sculptures by artist Jason deCaires Taylor was designed not only to encourage appreciation of the arts, but also to draw traffic away from nearby natural reefs, which were starting to show the strain of 750,000 visitors a year.
The museum comprises more than 400 original sculptures, which also serve as artificial reefs. Many are of human figures, making the ocean floor resemble some beautifully spooky lost world, its inhabitants frozen in space and time.
MUSA is divided into two galleries, one of which is accessible to both divers and snorkelers, the others to snorkelers only. To visit, contact a Cancun dive or snorkel operation such as Delfin Diving, Aquaworld or Aqua Adventures.

Guests starving for food or company can spring for the deluxe package, which includes a dinner drop-off.

Ithaa Undersea Restaurant, Maldives
There are only 12 seats at this restaurant — but all of them have fantastic views of the Indian Ocean overhead.
Now located five meters below sea level, the world’s first underwater restaurant serves “Maldivian-Western fusion cuisine” in a stunning all-glass setting.
Prices aren’t cheap, but it’s not every dining experience that can boast a panoramic view of the very sea life you might be eating.
Fun fact: The restaurant is also available for weddings.
