Stayed 3 nights in late June. Easy access to Many Glacier area (30 minutes north), Going to the Sun (it's on it), walking trail to Visitor Center. Bathrooms were kept clean and showers were adequate (not the Ritz, people). Sites were well distributed so didn't feel on top of each other. Pull through sites made an easy job of arrival & ... more

Like many of the national park campgrounds, this campground is showing its age. The facilities are worn and very dated but they do have showers in a central location on each loop. Water spigots are spread out throughout the grounds. This is the only Glacier campground with cell service.

Pros: Centrally located Free hot showers Reservable during the summer Visitor center within walking distance for shuttle service, maps, or free WiFi Dump station Grey water sinks Flush toilets in all bathrooms Site A05 had enough underbrush to make it private Cons: NO shade in most sites and NO privacy Road noise on GT... more

Supposedly this is a reservation only campground. There was s full sign on the campground but we took a chance and saw someone leaving and got his site.But there were plenty of unused sites so don’t believe the full sign.( apparently people make reservations and never bother to cancel them ) If you come after 8 pm you’ll have no trou... more

We found this campground to be far less desirable than Two Medicine, where we spent the majority of our time on the east side of Glacier. Sites at St. Mary were extremely unlevel (side to side and front to back) and we had trouble getting into the site because of the overgrown shrubs along the sides which scratched the trailer. Sites a... more

It's exactly what you'd expect from a busy National Park campground in the middle of August. It was fully booked and crowded but we snuggled into our site and had a wonderful time. We arrived on a Monday afternoon and upon receiving our site map proceeded to drive the loop road only to find we were booked in a site with a shared drive-... more

We enjoyed our stay here a lot. Comfortable feel to the campground. Even went to a presentation by one of the park rangers. We didn't make it to the astronomy presentation at the St Mary visitor center, just didn't work out. Looked interesting though. They had a good size telescope for the presentation. Loop C has free hot showers a... more

We lucked out and had someone who had an extra spot offer this spot up to us at the last minute and we were thrilled to be in the park! The campground is probably pretty typical of a national park, built before the rigs were very large...and while we don't feel large at 27 feet, the pull through sites are all curved, so many of them a... more

We parked a 31ft travel trailer in this spot for 4 days, 3 nights. Unfortunately, you enter the site with right side of the trailer facing the road. We were able to do a 180 with the trailer to have it facing the fire pit and picnic table and upon departing, was able to flip it around again. With the limited use of a generator (... more

The best National Park Campground we ever stayed in, but only because it wasn't high season yet. We stayed here during Memorial day, and the campground was basically empty, even with only the C loop open. The C loop has the best views of St.Mary, with 101/103/105 being the prime spots. In my humble opinion C101 is the best spot in ... more
