Visited Big Lake State Campground in May of 2023. Beautiful location. We were one of 2 RV's in this campground on a Sunday night. There were picnic tables and fire pit for each site, clean pit toilets, and plenty of garbage cans but no other amenities (no water or electricity) $20/night. Sites were fairly level and most of them were on the water with some scrub brush blocking most of the view. The North Country Trail connects to this campground. From Google Maps view the lake level was down considerably but still very beautiful and a peaceful stay besides the mosquitos- biggest I've seen in my life. Bring a screen porch and head netting- you'll thank yourself for both of them.
