I have mixed feelings about Robbers Cave - there are so many different campgrounds and some are much better than others. First of all, you have all the campgrounds around the lakes in the main park area. The only one with decent bathrooms is the RV site on far side of the road from the lakes. The rest either have vault toilets or top of the line 1940's, never been upgrade bathrooms. However, if you don't mind primitive camping there are a ton of spots on the other side of the lakes that are less busy and although without bathrooms, if you stayed on the main side you may decide no bathroom is better than some. The hiking is great in this area either way. Definitely due a visit. Campgrounds mainly in treed areas. The park gets a lot of day use, so expect very crowded afternoons if you are in the main gate area, the crowds leave after dark though.
