You can access the loop from various points along both the C-470 Bikeway and the Mary Carter Greenway. Many cyclists start near Chatfield State Park, where the two trails connect. Look for parking areas within the state park or at various trailheads along the greenway, such as those in Littleton or Englewood. For specific parking information, you might check local city or park websites like visitlittleton.org.
While the trails themselves generally do not require permits, if you choose to start or park within Chatfield State Park, you will need to pay the state park entrance fee. Check the Colorado Parks and Wildlife website for current fee information.

The spring, summer, and fall months are ideal for cycling this loop. The trails are well-maintained and accessible during these seasons. Autumn offers pleasant temperatures and potentially scenic views as foliage changes. Always check local weather conditions before heading out.

The Mary Carter Greenway also has a dedicated paved path for cyclists, often running alongside a crushed stone path for pedestrians.
The loop offers varied scenery. The C-470 Bikeway provides open views of the Colorado foothills. The Mary Carter Greenway, running along the South Platte River, offers pleasant water views and traverses 880 acres of open space, with award-winning landscaping and interpretive sites. The southern end of the greenway is particularly wide open.

The Mary Carter Greenway's northern end links to the South Platte River Trail and the Bear Creek Trail. This route specifically uses sections of the 470 Trail, Mary Carter Greenway Trail, and South Platte River Trail, among others.
Yes, dogs are generally allowed on both the C-470 Bikeway and the Mary Carter Greenway. However, they must be kept on a leash at all times, and you are responsible for cleaning up after your pet. Always be mindful of other trail users.
