We just camped at Lake Casita Recreational grounds this month. There are several campsites in the area. Each campsites have different features, basic campsites have water available and vaulted toilets, and some sites have hookups for RV. The recreational grounds have picnic areas/tables and beautiful view of the lake. We stayed at the Indian campgrounds which has water and electricity hookups on each site. The campsite here are very close proximity to each other and there isn’t much view of the mountain nor the lake. I would probably recommend Osprey campground which has more space in between sites and has a beautiful clear view of the lake. There are lots of bird in the area and you can bring boats or practice fishing in the lake. No swimming is allowed in the lake. The water park is closed for renovations at this time and is announced to open next summer.
