Always loved this beautiful spring,my whole life,it has a wide range of areas for nearly every level swimmer, from a wide shady shallows for babies and family,with grassy null for good picnicking to the moderately deep for more experienced with various depths gradually deeper and bluer towards the boiler,with areas of white bottom,patches of green and schools of fish,or large limestone rocks, on to the rocky-walled and majestic deep blue boiler,witch is comfortably large at,I'm guessing, 50ft across and 40feet deep,last time i checked, like 16 years ago. I did like it better before the installment of concrete and safety rails back when i was a kid,it was more natural and free feeling...i could adventure and discover more.now I'm closed off from the best areas i used to play.but,the boardwalk is a wonderful improvement, back when i was young, it was mostly inaccessible because it was falling apart, thus me and my brothers would explore that area by way of the cypress woods before emerging out onto the riverside across from a boat ramp,next to the slew where the springs empties into it..now a beautiful large seated gazebo overlooks the spot and the walkway is wide and many rest benches along the way.its lovely,but you are no longer allowed to venture free in the cypress knees, and for good reason,wild life. I wish they would start red belly day festival again, i know many folks who miss it so much. I loved the belly flop contest,i was a fat kid and could make a decent splash,but was too embarrassed about being overweight to ware a bikini, so i never won,but it was sure fun.i was too young for the fishing part of the contests,but there was many other things to do, the foods,crafts,music....well,that's all for now,y'all have a good time now,and please show respect for my beautiful pastime swimming hole!
