This was my first trip to Rainbow River and was pleasantly surprised by the lack of people there, (Oct-April). Only $3 to enter and park car, (other springs charge $35+ to dive). We rented a canoe and put all our gear (2 of us) and paddled up river. Careful not to go too far as we passed the 'hole' and didn't realize until we saw the sign 'no diving' at the state park. Depth ranged from 5-22' and had some fun things to look at. Temp always around 72 degrees and water viz is very good. Nice fun dive when the ocean waters are too cold and the fresh water is a plus.
