Lost Canyon Ranch Open Space opened to the public July 13 with 10 miles of hiking trails across a 681-acre property. Castle Rock’s opening notice identified two accessible trails, parking at two trailheads and a connection to Castlewood Canyon State Park.
The property at 6581 Lost Canyon Ranch Road was acquired in 2024 through a partnership involving the town, Douglas County, Great Outdoors Colorado, Douglas Land Conservancy and The Conservation Fund. Public input helped shape the master plan approved in 2025.
The July announcement said another five miles of trails remained under construction. It also set visitor limits to protect habitat: dogs and horses were not permitted, and bicycles were restricted to roadways. Visitors planning a later trip should check the linked property page for seasonal hours and construction updates, rather than relying on the summer hours in the opening notice.
