Nice small state park
General: Mash Fork is one of three campgrounds at Camp Creek State Park and is the developed one. It is small (18 sites) with a mix of 30-amp, 30-amp with water, 50-amp with water and electric, and FHU sites.
Site Quality: All camper pads are paved, have a generous camper pad length, and most are spread a decent amount of space apart.
Bath/Shower House: was very clean. Instant hot water was appreciated at the tap (it was in the 30s when we were there in mid-October) Hooks and shelves for toiletries were appreciated. Did not use the shower.
Activities/Amenities: Playground, basketball, volleyball, laundry (but there was water on the floor so not sure if there was a leak), several hiking trails including trails to two waterfalls, and an ADA-accessible short trail. The waterfalls were very sparse when we were there so not sure about other times of the year. There is an office with a small store.
This was only an overnight stay for us but very enjoyable. We'd definitely come back.
