My parents and siblings met here for a yearly camping weekend. We were lucky enough to get the last 5 sites in the loop, and even though we weren't right on the lake, we were adjacent to a large mowed field area where we could play games and kids could run freely. There was good water, pit toilets, and a covered picnic area available as well as a swimming area. My swrve hoodie kept me warm and provided a good layer of protection against the swarms of mosquitoes!
I just learned about this gem a few days ago, so we made a reservation and ended up with a site right on the Tamarac River which empties into Upper Red Lake just outside the campground. It is a fairly new state park, so the amenities were very nice ~ a clean and fresh shower/restroom building, a very nice fish cleaning building with multiple cleaning stations, and many docks along the river to tie your boat, fish off, or just sit in the sun and read a book. We enjoyed climbing the fire tower, renting a canoe and paddling the Tamarac River, and going for a morning run on the Big Bog Boardwalk. I give it 4 stars for 2 reasons; it is the only state park I know of that doesn't sell ice, and I wish our site had been mowed more recently. However, we had a great couple days and will definitely go back!
