We had a lot of fun tent camping at Beaver Lake with our two daughters (4 and 6) and two dogs. Loons on the lake, and lots of frogs. The mosquitos were VERY heavy, but we managed with bug spray and campfires. We thought the outhouses were unexpectedly nice despite previous reviewer’s comment. Though, we often travel to the BWCA, so really depends on your level of camping and being in the woods!
Our biggest issue with the site was not having direct access to the water for the girls to swim, or to use the canoe (an issue for most of the sites at this campground because many are not on the water at all). There was 1 camp spot with direct water access and even had a small beach. There is a boat landing across the lake, but this was hard for us with the girls.
