We stayed during Bigfoot weekend. It was super fun as our family likes bigfoot fun. We started out Friday night getting the offered $12 bbq plate that included pork burnt ends, beans and potato salad that were "oh it's so good". On Saturday was rock painting and then bingo and ended the night with a DJ dance party. The pavilion where all those activities happened were right next to our site (22 with the doggie den). Then Sunday we had pancakes and later a visit from RayCEP which is an education program that PA DNCR provides talking about various outdoorsy type things. This is primarily for kids, but we sat and listened too and our 17 year old helped out with the craft.
After the weekend though, all the activity slows down. There are seasonal campers that stay around, and they're constantly working on improving and fixing up sites during the week. Expect lots of quiet time just relaxing during the week. There's the pool, dog park, bounce pillow, playground, but not tons to do which if you're looking for is great. Raystown Lake has multiple access areas that are probably 15-20 minutes away - we fished at Tautman Run and Aitch - both were accessible and had lots of bluegill to steal our worms.
Now to the site description: Site 22 is a deluxe patio back in site with a patio, 4 nice Adirondack chairs, a double glider, a weber propane grill and built in fire pit AND a dog fence just for that site that was maybe 6 ft x 6ft. it was big enough for our 2 labs to fit into when we fed them. The site wasn't hard to level our RV but overall the sites are hilly and in fact the whole park is on a hill.
The owners and workers were friendly and great hosts! We love what they're doing there.
One last tip: if traveling from the Altoona area, go out through Martinsburg over Cove Mountain Rd - it saves you 30 minutes to an hour.
Whether your stopping overnight on the way to somewhere or staying the weekend, this is a great place to park. We got the pull through at the end of one loop so we could face the woods. The site wasn't so level, but we made it work.
