The North St. Vrain Backcountry Campsite hides in a lodgepole pine forest. It sits on the north side of Thunder Lake Trail after it crosses North St. Vrain Creek in Rocky Mountain National Park’s Wild Basin. The two-site camping area makes an ideal base camp if you’re hiking up to Mertensia Falls, Thunder Lake, Lion Lake, and Trio Falls. The campsite, lying at 9,560 feet, is 3.5 miles up Thunder Lake Trail from the Wild Basin Trailhead. The trail gains 1,060 feet of elevation from car to camp. Allow three or four hours to backpack to the site. The campsite has a privy between its two sites. Get water from North St. Vrain Creek, but boil or treat it before use. The campsite is free of snow by June 1.
Recommended season(s): June to September.
