This hiking and equestrian trail connects Las Trampas Regional Wilderness to Mount Diablo State Park. Completed in 1997, this five-mile trail connects two of the most significant open space parklands in central Contra Costa County. Planning for the trail dates back to the Park District’s 1973 Master Plan and rights-of-way and trail easements were purchased in the 1970s.

Leaving the eastern edge of Las Trampas at Camille Lane in Alamo, the trail goes through Hap Magee Ranch Park in Danville, passes under I-680, weaves its way over the ridge, crosses Stone Valley Road in Alamo, ascends the grassland and chaparral-dotted slopes overlooking the valley, and enters Mt. Diablo State Park at Macedo Ranch Gate. Passing through residential and open space areas, it provides convenient access and offers an interesting contrast between development and parkland.

Ancient oaks, rolling hills, and spectacular views greet those willing to challenge this unique regional trail. Access to the trail for equestrians is most convenient at Macedo Ranch Gate at the north end of Green Valley Road above Danville. For hikers, Macedo Ranch Gate on the north end, La Gonda Way on the south end, or Oak Hill Park in the middle (at Stone Valley Road and Glenwood Court, in Alamo) are the best access points. At Macedo Ranch Staging Area in Alamo, the trail connects with the Briones to Mt. Diablo and Green Valley regional trails
