This campground was very well maintained. The sites are rather close together but the trees and convenience is great. Mountain bike trails are accessible from camp and town is just a few blocks away. Restrooms and showers (pay) were very clean.
We hadn't done much research in this area and hadn't planned where to go so we decided to "glamp" at the KOA. For a KOA this was pretty nice. Restrooms were clean. Lots of activities for children. It was expensive for close together sites and only electric and water hookups. We did have a nice shade tree however and were able to run our A/C. The proximity to Dinosaur National Monument was the reason we stayed 2 nights. We explored the Utah part of the Monument (where the dinosaurs are) and thoroughly enjoyed seeing the quarry, petroglyphs and cabin.
We were looking for an overnight stay while traveling through Idaho. We didn't arrive until 5pm and were certain the campground would be full. Much to our surprise it was not full but we were not told how many sites were available so pretty much took the first site we saw. It was a huge site for our little rig but we grabbed it anyway. We enjoyed visiting the park in the evening and having it almost entirely by ourselves. We also had a little time in the morning to catch some areas we missed the night before and also had this time to ourselves. Had we not stayed in the park I'm not sure we would have had time to visit on our way (20miles) to the next nearest campground. The park is fascinating and worth the drive.
We were in need of a place to camp as were were driving through OR. Found this location and decided to give it a try. We kept tabs on the website and determined we would forgo a reservation for a mid-week overnighter. The sites with hookups filled up for the night but not the dry camping sites. Plus there is an overflow area. The natural hot spring pool was wonderful and large enough to accommodate quite a few people. We met folks from near Bend that come to this place regularly.
The $30 dry camping fee included unlimited use of the hot spring pool, showers and restroom (There were no electrical outlets in the restroom for those wanting to use a hair dryer). Others have described the other amenities so I won't.
Curlew National Grasslands is a tiny area near Snowville, UT. We were looking for a quiet place for an "overnight/passing through the area" spot. Easy to reach with only 1/2 mile at most gravel. Our experience was on a Tuesday. NO ONE ELSE was camped there except the campground host who was camped in what we thought was the day area. Covered picnic tables, fire rings, clean outhouses and flat sites.
