Stayed at Blue Mounds on one of the hottest weekends this summer! We booked site 12 initially based off of reviews from the Dyrt suggesting riverside sites. Site 11 and 12 were NOT good. There's a dumpster in the middle of the two sites, absolutely no privacy, and no shade. Thankfully, there is good cell service (and free wifi!), and we looked up what other sites were open. 13 was open! And boy did we luck out with this. Even though it's just adjacent, 13 had a nice little secluded area for our tent, and a *private* riverside walk out to the cliffs overlooking the river! No direct river access- it's about a 15 foot drop to the river. The moonrise from this site was gorgeous. Had a spooky visit from the Starlink satellites. We drove in the morning to the bison area and saw about 12 of them roaming near the fence.  Bathrooms were decent. Close by to Luverne for any last minute needs while camping.
