Belly River Campground

This campground is now completely open. When we arrived they had the front loop, with 7 campsites, closed due to problems with a bear. This loop opened during our stay. The sites are a bit small and not very level, but there were multiple sites that could have accomodated our 25' trailer. Interestingly, the bathrooms are flush but there is no water available here.

The border crossing just south of here is closed due to low volume and that makes for using the road as a nice trail to walk to the border and back. (7 miles roundtrip)

Lots of wildlife, foxes, bears, moose. We didn't see the bear, but saw the foxes and moose. The first night a fox tried to drag off one of my boots and on the last night at 4am two juveniles were playing in the campsite running around and tugging on our camping mat. it was cute to watch them.

No T-Mobile coverage, but our Starlink worked great. 100mbps down and 25 up.

We loved our stay here, just a few miles from the border. Very quiet with a pretty view across a meadow (some other sites were more wooded). Probably not so good with a large rig, most vehicles were class B/B+.
The camp host let campers know there was a fox in an empty campsite- I’m surprised we didn’t see more wildlife given the surroundings.

If you want to explore Waterton Lakes National Park and don't want to camp in the zoo-like "Townsite" campground in-town, Belly River is a great option. The sites are a little small for any RV above 25 feet, but the spots are very private from each other and there aren't that many of them. Also, in our experience it was easy getting a spot without reservations, even on a Saturday in July.
