I agree with with nearly all said by previous July 2011 reviewer. There are 33 sites including 1 hike/bike site and 1 accessible site #3 which is the only pull through site and the only site currently with 30 amp service and water but no sewer. Stayed 7 nights Sunday to Sunday. Best time is Sunday through Thursday as park is empty. Friday and Saturday is completely full and a bit of a madhouse. State Park staff and campground volunteer host are very friendly and attentive to the park. Ranger makes nightly drive/walk through entire park looking for troublemakers. Restrooms and showers are cleaned 2-3 times each day. Trailer limit is 24 feet. There is a small nature trail surrounding the park. We camped here in a Travel Trailer.
This state park also has another campground, Stone Creek with 46 campsites. Idyllwild Campground is in a forest next to the town; Stone Creek is 6 miles north surrounded by manzanita bushes. Out of 30 sites at Idyllwild Campground, 9 are tent only and the rest are tent & RV, 2 pull throughs. Water and sewer hook ups are available in a few sites such as site 26 where we stayed. Almost immaculate restrooms and showers. Activities within 2 miles include antiquing, restaurant/bar hopping, nature viewing, hiking, rock climbing, fishing at Strawberry Creek and campfire programs on Saturday evenings in the summer. The staff are serious about enforcing noise and 8 person per site rules. The only drawback was Camp Maranatha next door which had some raucous activities. We camped here in a Motorhome.
