The hike to the falls is a must-do. Like others said, it gets crowded in the summer. There’s a nice 6 mile loop with lots of hills, and plenty shorter hikes around the lake a dam. Camp in the 100 or 200 sites for a more peaceful camping experience. There’s a small beach and boat launch, and plenty of picnic sites. We also biked on the st croix river trail, and enjoyed the cute small towns on both sides of the river. For rvs, this is the dream campground. There’s wide gravel and mostly level sites, with plenty of space for slide outs. Big sites, yet private ! Nice bathrooms and great showers in the 100 campground. Can’t wait to come here again!!
