Recently took a road trip from New England to Florida with my family and had the pleasure of staying here at the Jonathan Dickinson State Park.
This state park accommodates RVs, tent sites, and cabin rentals with two camping areas -- one (Pine Grove Campground) located close to the entrance, right off of US Hwy 1 and seems to be more geared towards RV sites and the other (River Campground) located about four miles into the park along the Loxahatchee River. We stayed in the River Campground.
Spacious sites offered: water, electricity, a picnic table, & a fire ring… and grounds include two well kept bathhouses with laundry facilities. Trees were sparse in some sections so be prepared to create shade. Our site was visited by a young raccoon who didn't seem fazed by us at all; just wanted what we were cooking.
We only stayed for one night, so we weren't able to take in all the park has to offer, but we did walk some of the nature trails along the river towards the newly built amphitheater and swimming area. Unfortunate for us, the swimming area was closed during our stay -- which would have made the stay twice as nice… but the views were still incredible!
If we ever find our way back to south Florida for camping, we'll definitely come back here.
