Boulder Lake is the larger of the two campgrounds here at Wakonda State Park. It is also crowded with RV and campers in the main part of the campground, with a small loop that is sort of tent only. The tent part is a loop with sites in the middle (37-50) having the best trees for hammocks and the sites on the outside of the loop having the most level places for pitching a tent. If you can get site 44, you have probably the best site in the campground as it sits at the end of the loop with no close neighbors, close to the lake, and backs to nice trees. None of the other sites are as private. This site is the furthest from the bathrooms and shower house, however. You can purchase ice and wood, and there are laundry facilities. All of this is located near the shower house. There are a couple of water spikots scattered around the campgrounds, and there is one hiking trail that heads out of the campground near the woodlot. Elsewhere in the park is a nice swimming beach with a place to shower off the sand, and some interesting cement tunnels/bunkers that kids might have fun exploring.
