Popular Lyons Mountain Biking Trails
• 100 ★ 4.2 • 1 mile • 448 ft • 2,530 •
Upper Bitterbrush is a bi-directional trail used to access the Nelson loop at the top of Hall ranch. The climb up is smooth, sustained, and easy. The descent is very fast and fun, mostly smooth with only one or two rocky sections!
• 100 ★ 4.7 • 2 miles • 323 ft • 2,410 •
Nelson loop is when the fun descending of Hall Ranch begins! Climb all the way up to Nelson loop and prepare for a fast descent the entire way down! This trail is a bi-directional loop but is best when ridden in a clockwise direction....
• 95 ★ 3.8 • 4,931 ft • 0 ft • 2,139 •
Antelope is a fun trail both climbing and descending. This trail is mostly used as an alternative to climbing or descending the very technical Lower Bitterbrush trail and can be used to access the upper parts of Hall ranch. Expect fun...
• 90 ★ 4.4 • 2 miles • 61 ft • 1,987 •
Very deserving of its black diamond rating. Lower Bitterbrush reminds me of desert riding in southern Utah, almost like a steeper version of UPS/LPS in Moab. Suffice it to say, there are many technical rock features, interspersed with...
• 85 ★ 4.0 • 5 miles • 990 ft • 1,501 •
Picture Rock is a critical link trail out of Lyons. It's insanely popular, but for a good reason. Want to ride out of town and do some miles and come back for a beer? This trail has your name on it! It's sort of a Jekyll and Hyde trail....
• 75 ★ 3.4 • 2 miles • 526 ft • 1,372 •
Voted one of the best after-work trails in Boulder County (well, by just one dude who wrote this), and also one of the most filling-removing trails in Boulder County by everyone with a hardtail bike, Wapiti is an action-packed,...
• 60 ★ 3.4 • 3 miles • 291 ft • 1,171 •
This trail is a really hoot! You can't go wrong adding this to your ride at Heil! So many people want to ride this clockwise (from the overlook past Picture Rock and then up to Wapiti), but they are missing out. Okay, to be clear going...
• 40 ★ 3.9 • 3 miles • 269 ft • 708 •
Fast and flowy through the trees. The Ponderosa Loop sits on top of a mesa and is accessible either from the south via Left Hand canyon and the Wapiti trail or from the north via Lyons and the Picture Rock trail. The Boulder...
