Nice campground close to the spring. Good hiking trails. Biking is iffy because of the loose sand, but doable. Just be ready for that fast stop in loose sand.
I believe they built a new bathhouse recently.
Be sure to have all your supplies as the closest town is a bit of a drive. Cell service was marginal.
The snack bar at the spring, when we were there, was an awesome bbq.
There’s a nice boardwalk along the spring run. We were there when there were no manatees so swimming was nice, but cool. Always 72°
