East Valley Trail

Highlight (Segment) • Trail

The East Valley Trail runs parallel to the main road through a beautiful open meadow. You get fantastic views of the striking red cliffs that separate the meadow from the shores of Horsetooth Reservoir, but there are several short spur trails along the East Valley Trail that will take you down to various inlets. This trail is relatively flat and accessible and is also open to horses and mountain bikers.

Arthur's Rock Trailhead

Highlight • Parking

The Arthurs Rock Trailhead is located at the very end of Lodgepole Drive. There is a large parking area, trail information, and vault toilets. From this trailhead you can access popular trails like the Arthurs Rock Trail, the South Valley Loop, and the Overlook Trail. This lot can fill up quickly, especially on beautiful weekends in the spring, summer, and fall so be sure to arrive early and try to carpool with a hiking buddy!
