Right Above Boulder – Know Before You Go:

The trails crisscrossing the five peaks that lord over Boulder are managed by either Boulder County or the city. Both maintain frequently updated, highly useful websites. Visit and click on “2017 Major Trail Projects” to find an interactive map of all trails managed by the city of Boulder Open Space and Mountain Parks (OSMP), with updated information on trail closures, as well as trails managed by the county. Hiking vs. multi-use functions of the trails are also marked.

An easy-to-use list of county-managed trails features icons clearly marking the allowed uses and recreational opportunities, like fishing and climbing, on every county trail. Access it via

Tip: As you get to know your favorite trails, take note of which agencies operate them. That way, you’ll know exactly where to check online for closures. County-managed trails are clearly marked “Boulder County Parks and Open Space.” City trails are often scantily marked, or might be posted with signs that include “City of Boulder Open Space and Mountain Parks.”

Located along I-70, just 20 miles west of Denver, Clear Creek County’s historic mining towns of Idaho Springs, Empire, Georgetown and Silver Plume, and the surrounding forests, are rich with history and beauty. Avoid the crowds and enjoy a simple day trip or a weekend getaway.

Georgetown’s Guanella Pass Scenic Byway is located a few minutes off I-70, just west of historic downtown Georgetown. The 23-mile paved and gravel byway goes past aspen groves, gorgeous waterfalls and wildlife. Be sure to bring your hiking boots to take advantage of the many trailheads along the way, including direct access to Mount Bierstadt, one of four “14ers” (peaks over 14,000 feet) in the county.

Eldorado Canyon State Park

Eldorado Canyon State Park is 5 miles south of Boulder on Colorado Highway 170 adjoining Eldorado Springs. The 1,442-acre park is a world-renowned rock-climbing area, with over 500 routes on cliffs rising more than 850 feet above South Boulder Creek. For nonclimbers, Eldorado offers fishing along South Boulder Creek and several hiking trails. The Eldorado Canyon Trail, open to hikers and horses, gains 1,000 feet in elevation and leads 3.2 miles (one way) to the 7.5-mile Walker Ranch Loop Trail (open to hiking and mountain biking, and partially open to horses). The Walker Ranch Loop can also be accessed off Gross Dam Road and Flagstaff Drive.

The Rattlesnake Gulch Trail has reopened since the 2013 flood, but the Upper Loop may be closed to protect nesting golden eagles. This trail is used by hikers and mountain bikers, and gains 800 feet in elevation as it leads over 1.4 miles to the few remaining bricks of the once-great Crags Hotel. From the ruin, the 1.2-mile Upper Loop that gains 325 feet in elevation leads to views of the Continental Divide to the west. Fowler Trail is wheelchair accessible for one-half mile to the Bastille, and then continues 0.2 miles to the park boundary, a total of 0.7 miles one way. This trail offers the best views of the inner canyon and the rock climbers. A self-guided nature-walk brochure for this trail, available at the visitor center, explores Eldorado Canyon’s unique environment. Streamside Trail is an easy half-mile hike (one-way) along South Boulder Creek. The first 300 feet are wheelchair accessible.

Throughout the year, the daily pass fee is $8 per vehicle at the gate. An annual pass valid at all state parks or recreation areas may be purchased at the gate. Cost is $70 ($60 for Colorado seniors).

Mount Evans Scenic Byway/Echo Lake

The 28-mile Mount Evans Scenic and Historic Byway is the nation’s highest auto road.

Ask a Ranger:
How to Spot a Golden Eagle

OSMP ranger Rick Hatfield has been a guardian of Boulder County birds of prey since he began volunteering with the city in the early ’90s. Peregrine falcons, prairie falcons and the elusive golden eagle make their nests in the rocky bluffs around the foothills. Except for the second Flatiron, most of these rocky areas are closed from February through July to protect the delicate habitats the birds nest in during that time. You might spot these raptors flying high above the canopy, duking it out for airspace, or soaring with undulating or circular flight patterns to impress their mates.

  • Third Peak’s the Charm: To spot one of the birds, Hatfield recommends the Arch trail at the southern boundary of the third Flatiron, as well as Skunk Canyon, Fern Canyon and Bear Canyon.
  • Ears Wide Open: “Most people will hear them before they see them,” says Hatfield. Find a quiet trail and listen for shrill, repetitive peeping. Then look up.
  • Don’t Overthink It: You may encounter bird-watchers on the trails with binoculars and spotting scopes, but Hatfield says the eagles, which fly above the canopy, are still visible to the naked eye.
