Our site was at Indian Meadows and it is large enough to fit my big 8-person tent, a picnic table, my truck, and all our other stuff with room to spare. The sites are very close to each other. The sites at Riverview and Silva both seemed smaller. The Riverview sites had great shade and a breeze coming off of the Mississippi river but had very little privacy. Each site at Indian Meadows and Silva are surrounded by a wall of trees. Our site had a picnic table and a fire pit with a swing over grill. There was no trash can, though. My plan was to collect the garbage then walk it to the trash point, a dumpster up the road. Unfortunately, while we were at the shower house raccoons got into it. I was better prepared the second day. Just remember to bring trash bags and dispose of your trash often, the raccoons out there are brave. The Loud Thunder office is top-notch. They sell a few necessities like batteries, firewood, ice, and stuff for s’mores. Service was incredibly helpful and nice.
At the center of Loud Thunder is Lake George. Lake George is a boon for kayakers and anglers. For us, it was the highlight of the trip. Loud Thunder rents kayaks, john boats, pontoons, and mini-pontoons. I had never heard of a mini-pontoon prior to this trip; they are amazing and now I want one. For 30 dollars we navigated the lake for two hours. My son loved steering the boat. Even though we were in the sun there was a nice breeze. We could have easily spent another two hours on that lake.
There are also plenty of trails for horses, bikes, and hiking. The trail we went on started as a wide gravel path then narrowed to a single-track dirt path. It had one hard climb. The trail was very nice and led to some great views.
