We camped at Big Ridge Campground in Lost River State Park, Mathias West Virginia. The campground was a little tight for larger horse trailers, but I was just fine with my 22 foot LQ and truck. I believe my friends GN was 30' and she had no problem as well. They have electric, sewer and water hook ups and metal pole corrals. I would highly suggest requesting spots 1 & 2 or spots 10 & 11. They had the best access for large rigs, were nice and flat, easy in and out. The first day we took the trails from the campground to the top of the mountain. The views were amazing! The trails were rocky mountain switchbacks, but very dooable. I did not consider this a hard at all. The next day we rode the trails in Lost River State Park. There are a few that are marked for horses and some for hikers and bikes. I DO NOT recommend going on any trail not marked for horses. We did and the trails were barely 2 ft wide, with a very steep drop off. We did get off and walk alot of those trails for safety. I would recommend someone from the campground or the State Park give you clear directions on which trails to take, and which to avoid. This was an excellent trip and I would definitely go again! The owners of the campground, Leroy and Shirley, are so very sweet and they did check in on us twice a day during our stay.
