If you're in a big rig, don't even bother. We have a 40ft combo with only a 23ft TT and did not even attempt to back into one of the few spots that looked as if it *might* accomodate our set up. Instead, since it was off season, we parked in one of the parking lots. It worked out fine and the rangers didn't hassle us or anything, but it was less than ideal. That said, this state park is not to be missed if you're in the area, simply because of the cool geologic wonders of the sinks and the rise. Maybe visit the park as a day trip from one of Lander's other RV parks! We camped here in a Travel Trailer.
Such a treat, this little state park. Interesting trails and visitor center, very quiet campground (except for the lovely roar of the river), and some of the most unusual geology you'll ever camp next to. This is our idea of camping. But it's tiny. We have a 25' Class C and arrived at 4PM mid-week to find pretty much one of the only spots we'd fit in (and the CG was pretty empty). Not a big-rig friendly place, but there was a very skilled 5th wheel driver pulled into one of the sites. Come early, find a site, and enjoy the scenery. We camped here in a Motorhome.
This park was beautiful! We were at the end of a long drive and managed to find this park on the map. It was a bit of a drive south of Lander towards the Wind River Canyon. It was in a drainage up the canyon and was picture perfect. Typical state park provisions but was right next to a really cool river & was nice to hike around. Staff ware extremely friendly and helpful. For state park camping it was excellent! We camped here in a Tent.
