Big Dry Creek Trail follows an east-west course for 12 miles between Interstate 25 and Standley Lake in Westminster, one of Denver's northern suburbs. The trail is generally flat, with short stretches of moderate grade. The trail passes among open space, parks, and neighborhoods. At 99th Street, there is a short on-road section (approximately 1 mile).
Where the trail crosses under US 36, a connection to the US 36 Bikeway is possible; that paved pathway parallels the roadway between Denver and Boulder.
One of the easiest places to pick up the trail is at the Westminster Rec Center (at 104th and Sheridan), which is more or less central to the trail. Parking is also available at Standley Lake Park, Westminster City Park (2 places), Westfield Village Park, and Big Dry Creek Park (1700 W. 128th Ave.).
