Why dive here
With 87+ marine species recorded in the area - including bull sharks, dolphins, hammerhead sharks, seahorses and sea turtles - Rainbow Spring North offers some of Florida Keys's richest cave diving. Water ranges 19-32°C, warmest July, August, September.
Rainbow Spring North in the Florida Keys offers a freshwater diving experience focused on small fish species. We’ve seen sailfin mollies and both Eastern and Western mosquitofish darting through the aquatic plants. This site is best for macro enthusiasts or those looking for a quiet, different kind of dive. It's not a reef dive, so manage expectations accordingly.
