Clean park with full hookups. They sell propane and have a store, however they are rarely open. If you need propane you have to ring a large brass bell. If you need anything from the store, your better off driving into town. If you need to check in or out you have to call the camp host number listed on the door at the office/store.
BUT BEWARE: the owner is notorious for trying to slip additional charges on CC purchase, ie: $5 for toilet paper etc. so if you pay by credit card watch you statement closely. And if you call him out on it he WILL deny it.
