Frequently Asked Questions

This challenging mountain biking loop typically takes around 5 hours and 6 minutes to complete. However, your actual time may vary depending on your skill level, fitness, and how often you stop to enjoy the views or navigate technical sections.

Is the Heil, Hall, and Picture Rock Loop suitable for beginners?

The overall loop is rated as difficult due to its length and technical sections, particularly the upper, rocky parts of the Picture Rock Trail. While some sections within Heil Valley Ranch, like the Overland Loop and Schoolhouse Loop, are considered easier and family-friendly, the full loop is best suited for experienced and fit mountain bikers.

What is the terrain like on this mountain biking loop?

The terrain is highly varied, featuring characteristic Front Range rockiness throughout. The Picture Rock Trail offers a 'Jekyll and Hyde' experience: the upper section is quite rocky and technical with constant small rocks and larger obstacles, while the lower section transitions into a smoother, more flowy, and faster 'swoop-fest' with red-dirt mini-canyons. Heil Valley Ranch trails also have significant rockiness interspersed with some buff sections, undulations, and swooping turns.

It also passes through sections of the Wild Turkey, Bitterbrush Trail, Wapiti Trail, Nelson Loop Trail, Antelope Trail, Ponderosa Loop Trail, Night Hawk Trail, Lichen Loop Trail, and Grindstone Quarry Trail, serving as a critical link for creating longer rides.

What makes the Picture Rock Trail unique?

The Picture Rock Trail is unique because it was intentionally crafted by and for mountain bikers, making clever use of elevation and contour. It features pump-able rock features, a testament to its professional construction with sustainability in mind, and serves as a vital connection between Heil Ranch, Lyons, and Hall Ranch.

Are there any sections of the loop suitable for families or less experienced riders?
