Quickly climbing above the red sandstone cliffs along Highway 90 in western Colorado, P12 is a twisting scenic drive ending near an old log cabin from boom days of uranium mining. The western trailhead is almost blind, and the steep 300' loose gravel climb is just the beginning of the colorful drive around Lone Tree Mesa and along East Mesa Creek. The trail is semi-maintained gravel and dirt with sections that can be damaged after rainstorms. The entire route can be completed in 2WD with durable tires and high ground clearance. The trail is wide enough for all full-size overland vehicles and trailers. Camping along this route is limited to one large and scenic campsite found shortly after climbing up the hill from Highway 90. There is room for 4-5 vehicles with tents and a large rock fire ring. The two-story, multi-room log cabin is near the east end of the trail, immediately along the edge of the road. It appears to have been a homestead with other small structures and a chicken coup nearby. Please respect the site and leave it as you found it.
