Lake Waldina is a great park if you like company and fishing. The park is quiet but the regulars tend to walk up to you on a daily basis and talk your ear off.. that isn't a bad thing but I like to talk alot to

Colby Woods is just west of Lake Waldina and it too is a pretty nice park. If you have a family with children I would Rec. Waldina, great fishing from 2 docks and summer swimming. The water is quite high this year and the catfish were going crazy during Dec. I tend to only park the Yellow Rose RV where I can fish.
Just north of Ocala is Crescent City, there are MANY camp grounds. It is east of Salt Springs and we found one, Gerogetown Marina and it is 200 per month if you want to stay a month, 100 per week. WE opted for 2 months because it is on the lake.. back to that fishing thing again.
West of Gainesville is Old Town and we spent 2 weeks at Yellow Jacket. It is about 30 miles west of the Oaks Mall in Gainesville and right on the river. The catfish are slow there unless you fish the right hours of night. Owned by nice people and the place is beautiful. I will stay there again.
