Aquarena Center At Spring Lake

To dive in Spring Lake at Aquarena Springs you have to take a special certification class as a scientific diver. The lake is the habitat of 5 endangered species as well as home to archeological digs uncovering history from 10,000+ years ago. Visibility is as good as the Caribbean. Once you are certified you get to come back and do work dives for free. There are no purely recreational dives as it is an endangered habitat.
