Lost Park Campground has 12 campsites with a maximum trailer length of 22 feet; elevation is 10,000 feet; camping season at this campground begins in May and continues until the road is no longer accessible because of snow. Facilities include toilets, tables, and fire rings. There is no trash service or water at this campground.

The Campground also serves as the the Lost Park Trailhead, which provides access to Lost Creek Wilderness via the Wigwam Trail and the Brookside-McCurdy Trail. Originally used to drive cattle from Webster Park in Jefferson County over into Lost Park, the Wigwam trail accesses the east side of the Lost Creek Wilderness by following the Wigwam Creek drainage up to an open meadow called Wigwam Park and on to a saddle at the end of the valley. Beyond the saddle, the trail drops down into East Lost Park, then crosses Lost Creek and continues west up the creek to the Lost Park Trailhead. Granite domes along the trail present many opportunities for rock climbing and the nearby streams provide good fishing. Because the trail is almost entirely in designated wilderness, Wilderness regulations apply. This moderate trail is a total of 11 miles and intersects with the Brookside-McCurdy, Rolling Creek, and Goose Creek Trails enabling hikers to form their own loops.

Directions
From Jefferson, travel north of Highway 285 and turn right on to County Road 56 (Lost Park Road) and travel about 20 miles to the end of the road. The trailhead is located just before the Lost Park Campground and can be very difficult to access in the winter.
