We have stayed at this campground twice and both times it's been a very nice experience. The RV park is located on the opposite side of the river from Garner State Park.
The best campsites are those on the outer rim of the campground. The inner sites are closer together and you get to know your neighbors pretty well. There is a nice bathroom and showers at the campground. In the campground about 500 yards away there is a small store that you can buy general groceries.
The walk to the water isn't far, none of the RV sites are located directly on the river. The Frio is cold and the part of the river where this campsite is located is pretty deep (maybe 10-15 feet at the greatest. There are a few shallow areas for little ones to play at and a rope swing a little farther down the river.
Close by there is the 2nd largest colony of bats.
