I have a 22’ travel trailer I pull behind an F150. Since this campground is inside Rocky Mountain National Park, the roads are all paved.

The campground sites are situated around one-way driving loops, which are quite narrow. Best to pay attention to which side of the loop your site is on so your trailer door doesn’t open up onto the road. I think they error on the side of caution when it comes to the size of trailer fitting into each spot. At least for mine. They said max 26’ (trailer + tow vehicle), but I’m closer to 32’ and I fit fine. That may not be true of all campsites though. There is parking very close by if your tow vehicle can’t squeeze into the site.

My site didn’t have a whole lot of trees, but they planted a bunch of small ones to try and fix this years from now. Sites were level and had lots of space. Each had a fire pit and picnic table.

There were no hookups and no cell service (Verizon). They did have trash drop offs, water for cleaning pans and dishes, and bathrooms. It was very quiet at night. Generators are allowed but only for a couple times a day during short windows.

Glacier Basin campground is just a few miles from the Bear Lake trailhead. It was very nice to stay inside the park. Vehicle passes to get into National Parks were still required when I stayed and the lines to get in were very long and slow.
