Eagle Wind Trail - 3.95 Miles Round-Trip

140 million years ago the Rabbit Mountain area marked the western shore of an inland sea that stretched from the Gulf of Mexico to the Hudson Bay. It was tropical lowland covered by rivers, swamps and lagoons. This sea retreated approximately 65M years ago when tectonic forces pulled the earth's crust, resulting in a western uplift that formed the Rockies.

The uplift's ripples caused rocks to compress and bulge at its base, creating anticlines - or convex folds on the earth's surface. As the bulging anticline's softer sediments eroded, only hard ridges - known as Hogbacks - remained from the previously rounded hilltops.

Rabbit Mountain's position three miles east of similar anticline formations along the Front Range is unique. The complex movements of two faults in the area pushed these eroding anticlines east, and with a rare orientation: their steepest sides face east, and gentler slopes to the west.

This unusual location and orientation make it a natural landmark visible from three counties. Today Rabbit Mountain stands along this divisive uplift between the Saint Vrain drainage basin (south) and Big Thompson drainage basin (north).

Here the Great Plains meet the Rocky Mountain upslope, a rich ecological juxtaposition that brings plant and wildlife communities together from each. White tail deer, mule deer coyote, elk, fox, rabbit, raptors and rattlesnakes all call this area home.

The Eagle Wind Trail - a lollipop loop - leads up and around the west slope of Rabbit Mountain with terrific views across the Eastern Plains, Front Range and Continental Divide. Hikers, runners, cyclists and families will enjoy mild grades and good wildlife viewing throughout:

The trail heads northeast from the parking area on a winding course to the Little Thompson Overlook Trail split (.5 miles : 5,712'). Follow signs and (right) across the saddle spanning a hogback (north) and the plateau around which the Eagle Wind Trail loops (southeast).

Continue over the service road (which provides access to the Indian Mesa Trail) to the beginning of the Eagle Wind Trail Loop (1.0 mile : 5,802'). The following description travels clockwise on the loop:

The trail levels atop a sparsely treed mesa with rangy panoramas of the Front Range, Continental Divide and Eastern Plains. Mountain mahogany, ponderosa and pinyon pine dot the expansive tract before you, brightened by an array of sage, switchgrass, and array of flowers.

You'll merge briefly with a service road (1.45 miles : 5,825') through a wide clearing with views of Mt Meeker (13,911'), Longs Peak (14,259') and the Twin Sisters (11,428' - 11,413'). Veer off the service road (1.55 miles) and continue across the mesa.

In about two miles the trail turns sharply back northwest to begin the second, lower portion of the loop. This section undulates gently through heavier brush back to the beginning of the loop (2.95 miles : 5,802'). Just before completing the loop is an outcrop and interpretive sign that identifies peaks from the Eldorado Canyon Area (south of Boulder) to Rocky Mountain National Park (north). Retrace your steps back to the parking area (3.95 miles : 5,530).

Worth Noting

  • Fault movements in the Rabbit Mountain area have cracked rock under-layers, freeing water trapped beneath the surface to rise. There are seven natural springs in the Rabbit Mountain area.
  • The Rabbit Mountain area has been occupied for over 5000 years. Indigenous Indians were displaced in the 1800s by European settlers seeking gold and arable land. The granddaughter of forest ranger Jack Moomaw sold the land to Boulder County in 1984, establishing it as protected open space.
  • Rattlesnakes are common in the Rabbit Mountain area. While encounters are rare, be mindful of their presence and never place your hands or feet where you can't see them.

"Whomever is interested please note that if you want to mountain bike rabbit mountain trails, you are in for a big surprise. First of all' if you hate rocks then don't try to bike. I biked Eagle Wind trail and there's millions of rocks in the path. Some are big some are small but there are more rocks then trail.I had to dismount my bike every so often just to get through the trail. I think that Boulder County should make a path that has little to no rocks for mountain bikers in that same area. I hate to say it but Rabbit Mountain is better suited for hiking."

"We were looking for a trail to hike today. We hike all the time and are now looking for trails that we can get to. ( Trails not closed due to flood damage) Beautiful hike, beautiful sunset, AND elk bugling in the distance! Wow!"

"This is a good trail to hike early in the season. It's fairly easy and helped to build up my strength."
