Mount Falcon Park Castle Trail

Mount Falcon is the Jefferson County park above Morrison where John Brisben Walker built a stone mansion in 1909, planned a summer home for presidents on the ridge, and lost the mansion to lightning in 1918. The Castle Trail loop from the east trailhead climbs 1,750 feet from the foothills to the ruins and the ridge, with Red Rocks Amphitheatre below, Denver spread across the plains, and Mount Blue Sky behind. It is a hard climb for a park 30 minutes from downtown.

From the east trailhead near Morrison, the Castle Trail climbs at once, switchbacking up a dry, open slope with Red Rocks in view to the north. The first 2 miles gain most of the elevation, and the grade eases as the trail enters ponderosa on the ridge. At about 2.7 miles the trail reaches the Walker Home ruins: stone walls, fireplaces, and a foundation on a rocky point with a view over the city.

From the ruins, a short spur climbs to the Summer White House site, where a cornerstone from 1911 marks the presidential retreat that was never built, and another leads to the Eagle Eye Shelter and the lookout tower. To make the loop, return by the Walker's Dream trail or the Turkey Trot trail, which drops back to the east lot on the north side of the slope. The full loop with the Walker's Dream, Meadow, and Tower trails on top is about 7.5 miles; the ruins and back alone is about 5.6.

The east trailhead is off Colorado 8 south of Morrison: turn west on Forest Avenue, then Vine Street, to the lot at the end. It is free, has toilets, and fills by 8 AM on weekends year-round; the county closes the gate when it is full. The west trailhead, reached from Parmalee Gulch Road in Indian Hills, starts near the top and turns the same ruins into a flat 2-mile walk, which is the option for small kids.

Dogs are allowed on leash. Kids manage the loop if they hike; the ruins are the reward, and the west trailhead makes them a stroll. Mountain bikers use the Castle Trail and are common on weekends. Rattlesnakes live on the lower slope. Carry two liters; there is no water in the park. The ruins are stabilized but fragile; stay off the walls. Morrison has restaurants and the Red Rocks trails next door, and the Denver hikes page covers the other foothills parks.
