Jules’ Undersea Lodge: The Only US Hotel Underwater
There are very few places in the world that bring beauty, nature and history together in an unforgettable way. And when it comes to hotels, the Jules’ Undersea Lodge provides a unique experience.
Initially, the hotel located in Key Largo, Florida, was constructed as a marine life research lab. After it was closed down, the area was redesigned to provide guests, with the experience of a lifetime.
The room is over 30 feet deep stuck on the ocean floor, which makes it the only underwater hotel in the United States. Ever since 1986, when it was opened, the hotel offered guests the chance of waking up with amazing views of sea creatures swimming around them. However, scuba diving certification is required.
Currently, the Jules’ Undersea Lodge features one retreat including two bedrooms and one bathroom. Additionally, visitors can also attend the scuba diving school.
