Nestled near Boulder, Colorado, the Heil Valley Ranch bike trails serve up an exhilarating cocktail of scenic vistas, challenging terrains, and that unmistakable Front Range rockiness. At a moderate distance of 14 miles, these bike-legal trails are an intermediate cyclist's haven.
The trail system is smartly laid out in a figure-eight configuration around the mountain's peak and features two main approaches, one from the north and another from the south. Starting at the southern trailhead covers a 2.5-mile ascent, which is relatively shorter compared to the 5.5-mile northern trail. To experience the full spectrum of what Heil Valley Ranch offers, be prepared for at least 23-24 miles of pedaling. All this effort pays off, rewarding you with awe-inspiring views of the Front Range.
Heil Valley Ranch trails are characterized by their unique Front Range rockiness, accentuated by random patches of smoother, "buff" trail sections. The rocks aren’t intimidatingly large, making the ride relatively straightforward, especially for those familiar with Front Range trails. However, for optimal comfort, a full-suspension bike is recommended, although seasoned riders have conquered the trail on hardtails.
Be ready for a challenging but fulfilling climb. The uphill sections, especially if approached from the north, will test your stamina. But once at the top, prepare for the descent of a lifetime. Featuring a near-perfect blend of undulations, grade reversals, and swooping turns, the descent captures the very essence of flow.
The trail is popular, which means you should be cautious of oncoming traffic. Always ride in control and keep a lookout for other users to ensure everyone's safety. Yield to uphill riders and hikers.
The trail system is remarkably well-maintained and offers a range of facilities:
From Boulder, head North on Highway 36 to Lefthand Canyon Road and turn left. Proceed for about half a mile to Geer Canyon Road and turn right. Travel about 1 mile to reach the parking lot.
As of the most recent update, the trail is currently closed. Please check for the latest status before planning your trip.
Heil Valley Ranch offers a comprehensive biking experience, combining technical climbs with free-flowing descents against a backdrop of stunning Front Range vistas. It’s not just a trail; it's a biking pilgrimage every Boulder-area cyclist should undertake.
