Hiking
The Mary Carter Greenway Trail offers a unique long-distance hiking experience right in the Denver metropolitan area, following the South Platte River. You'll find a mostly flat, multi-use path, with a crushed stone section specifically for pedestrians, winding past scenic spots like Eaglewatch Lake and the South Platte Reservoir. It's a great way to immerse yourself in nature without leaving the city, though some northern sections do pass through more industrial areas.
This is a serious commitment in terms of time, rated as difficult due to its length of 20.3 miles (32.7 km), which typically takes around 8 hours and 15 minutes to complete. However, with only 186 feet (57 metres) of elevation gain, the terrain is very gentle, making it more about endurance than steep climbs. Parking is available at various access points, such as the "Park and Rafters" highlight, and the trail is well-connected to public transport options throughout Littleton.
The Mary Carter Greenway Trail is a testament to urban greenway development, having received national awards for its restoration efforts along the South Platte River. It serves as a vital artery in Denver's extensive trail network, linking to other major paths like the C-470 bikeway. Beyond hiking, you can find amenities like interpretive sites and even whitewater boating facilities, making it a versatile outdoor destination.
