Really enjoyed the Acorn campground - south end of park. There are many to choose from in this large state park, but I would return here. Site was level with the usual amenities all in working order and not too close to neighbors. The river ran directly behind the site and I was entertained by an otter family and ducks daily. There is a water release siren that sounds occasionally and it is loud, but it doesn't happen frequently, or at night, at least not during my stay.
Enjoyed the hiking in this park. Lots of great cleared trails. Often times I was the only hiker. A real gem is the COE access road that runs along the river past the spillway. If you walk far enough down you can view the real "wild" river with the islands of cypress trees and boulders creating eddies and the relaxing sounds of the river spilling over and around. 10 out of 10 stars
No Verizon service except at the nature center (definitely worth a visit especially if you have kiddos, and the ranger here is fantastic!!). You can jump on their wifi, or if I walked to the pavilion behind the store I could get one bar on my phone. Note off season store hours in photo. Not much in the store. The BBQ at the Lookout restaurant is the draw.
