They have 64 sites, most are pull throughs, all are full hook up. Roads are paved, sites are gravel. Each site has a picnic table and there is grass between the sites, some trees throughout the park. Most of the sites are pretty close together.
Amenities include: laundry, restrooms/showers, small store with a good selection of RV supplies, propane, free wifi and cable tv. We had excellent 4G Verizon signal so we used our own wifi during our stay. The laundry room did not open until 9am on Mon - Sat and 10am on Sun. (rather late in my opinion), but only the closing time of 9pm was posted...very annoying.
We enjoyed walking through the neighborhood behind the park to River Side City Park, about half a mile from the RV park, on the banks of the Flathead River.
At $280 for one week, this was an expensive place to stay...but the rate is typical for summer in a popular tourist area.
This was a decent place to stay but if you are going to spend a lot of time in Glacier National Park (GNP) it would be more convenient to stay closer to GNP. There is so much driving to get anywhere in GNP that the extra 15 miles each way from Columbia Falls was a bit much.
