This dive site is Three Sisters Springs, a unique freshwater complex comprising three distinct spring areas in Crystal River, Florida. It features numerous vents and sand boils that contribute to Kings Bay and the Crystal River system. Navigation involves exploring these interconnected spring basins and channels. The site is historically significant as one of the most vital natural warm-water refuges for the endangered Florida manatee, especially during colder months. Access is strictly controlled and boats are prohibited from entering the springs directly.
Divers and snorkelers can expect to encounter the majestic Florida manatee, often seen resting or feeding within the warm spring waters. The springs are also home to various freshwater fish species and turtles. While manatees are the star attraction, the ecosystem supports a range of unique spring life adapted to this specific environment.
The best time to visit Three Sisters Springs to see manatees is during the cooler winter months (typically November through March) when they seek refuge in the warmer spring waters. However, diving and snorkeling are regulated, with restrictions on entry when manatee numbers are high to protect the animals. Visitors are advised to check current regulations, maintain a respectful distance from wildlife, and consider early morning visits for fewer crowds and better interactions.
