JUL stands for the Jules' Undersea Lodge in Key Largo, Florida.
Read more about it here.
It has been featured on "Lifestyles of the Rich & Famous", in "Sports Illustrated Swim Suit Issue", in countless magazines and newspapers, and on every major television network in the world.
For the first time in history an authentic underwater research habitat is open to the average person--sport divers and even those who have never before dived. And although Jules' still functions as a research lab, you will be pleased to know that it has air-conditioning, hot showers, stereo music, VCR's, a fully stocked galley, and unlimited diving for certified divers!
Visit Innerspace and experience what was once only a dream of science fiction writers: living within the sea! In fact, Jules' Undersea Lodge is named after Jules Verne, and our goal is to be sure that Mr. Verne would be proud.
