Great place. Extremely friendly staff. Short, awesome bicycle ride to Everglades City. The view of the sunset on the bay is absolutely stunning. They offer fishing guide services and boat rentals.
There won't be much space between you and your neighbors, but let's be honest: if you're staying at this small island park, you're probably spending most of your time on the water. You can rent boat slips or launch a kayak; rent one if you don't have your own. Pick up your fishing supplies at the office. The historic Smallwood store is just a little farther down the road. There's 1 designated tent site, several RV sites, and a number of permanent residents. If you don't have your own RV, they have RVs and cabins for rent.
The park has bathrooms, a small playground, chickee for lounging outdoors, with a fire pit nearby, and a pavilion for gathering with friends and family.
