There are lots of campsites at Boysen State Park. I called the phone number and talked to a nice ranger. She suggested Upper Wind River campsite since we did not have boat and wanted to have a nice tent spot. We camped 1 week before site changed from reservation to FF. We planned on staying 2 nights but it was so relaxing we ended up staying 4. 1 day we went to Marina and swim beach. Another day we went to Thermopolis and checked out Dino museum and hot springs. Last day we just hung around camp and relaxed. Campsite had a park for kids. No showers but plenty of water so we set up privacy tent and we’re able to shower when we wanted. If we were there during peak season I bet it would feel a little crowded but was perfect the time of year we went because there were maybe 10 sites filled out of the 80ish there.
