You'll experience a dynamic landscape, transitioning from the smooth, paved Mary Carter Greenway Trail to more rugged dirt and gravel sections near Chatfield State Park and the High Line Canal Trail. The route follows the South Platte River, providing scenic views of lakes like Cooley Lake and Blackrock Lake, and passes through the natural beauty of South Platte Park and Carson Nature Center.
To make the most of this popular route, plan to start your ride early, especially on weekends, as the extensive trail network can get busy. While specific parking information for the Ken Caryl start isn't detailed, the area is generally well-equipped for trail access. The Mary Carter Greenway features a dual path system, with separate lanes for cyclists and pedestrians, which helps manage the flow of users.
This trail is a key part of Metro Denver's award-winning greenway network, connecting to other major trails like the Platte River Trail. It's celebrated for its successful rehabilitation of the South Platte River corridor, offering a natural oasis with opportunities for wildlife viewing and impressive fall colors in sections like Waterton Canyon, which is often incorporated into loops in this vicinity.
