Kelly Flats
Larimer County, Colorado
Kelly Flats is notorious for Heart Attack Hill—an extremely steep and rocky climb near the beginning of the trail. Rollovers and unintentional dismounts are a real risk and the alternate route isn’t that much easier. Once past the hill or its alternate, the two-track road flattens out and provides many scenic views.

Know Before You Go
- Maps and data files are from a variety of sources. Trail and area conditions vary widely and many trails and areas may have changed significantly since the map or data file was created. Use your discretion and check with the local land management agency before riding or driving on public lands. Ride and drive at your own risk. YOU ARE RESPONSIBLE!
- Not all routes are open to all vehicles. Follow the Motor Vehicle Use Maps (MVUMs) and signage for the area and ride only on trails open to and wider than your OHV. Almost all trails in Colorado are subject to seasonal restrictions and closures. Visit the road and trail closure info page for more information. Call the responsible agency before making plans to ride in an area.
- All off-highway vehicles operated in Colorado must have a registration or permit issued by Colorado State Parks including those of non-residents. For more information, visit the State Parks OHV Program Page. Street legal vehicles with valid license plates do not need to be registered.
