Mount Falcon 'Summer White House' Ruins

At the end of Walker's Dream Trail sits a marble cornerstone and foundation — all that remains of John Brisben Walker's quixotic plan to build a 22-room presidential castle on a Colorado mountaintop, a project he tried to fund by asking the nation's schoolchildren to mail in their pennies. The ruins sit at 7,851 feet in Jefferson County Open Space, surrounded by sweeping views of the foothills and the Denver basin.

The move: Hike the Castle Trail from the East Trailhead (roughly 2 miles each way, easy to moderate) to visit both the Walker Mansion ruins and the Summer White House cornerstone — read aloud the historical marker text about the penny-mailing campaign, then spread out a picnic at the nearby shelter with panoramic views before hiking back at golden hour.

Where: East Trailhead: 3852 Vine St, Morrison, CO 80465 (West Trailhead: 21074 Mt Falcon Rd, Indian Hills, CO 80454)
