Put in an hour of power and you'll still get back for dinner. This loop has lots to enjoy while including enough technical parts to keep any veteran focused. Navigation is very easy through Granby Ranch as there are several information kiosks throughout. Use this Ride as a starting point, but don't be afraid to modify the route or even hit the northern sections via Vista Ridge.

The trails at Granby Ranch are beautiful and there are many views of the valley and even some glimpses of Lake Granby. This loop will give you your money's worth with a lung workout and rocks and ruts to make you choose your lines wisely.

There's lots of variety from shaded glades to open hillsides (beetle kill cut) and the trails alternate between fast and smooth to slow and technical. If you aren't in shape, you probably won't enjoy yourself on the climbs.

Need to Know

Parking is fairly limited at this starting location. These are not heavily used trails, but an early start is best. Be alert for occasional riders and hikers.


From the small parking area, start up Main Street and make an early left onto Out of Gas. Riders will get a bit of rolling singletrack before encountering a technical spot at the intersection of Out of Gas and Lower Backside - scout your route before enjoying, or play it safe and walk it down. The bottom lacks a good run out, so I definitely recommend a scouting trip if it's your first time.

Once on the other side, keep going on the singletrack until the trail begins to switchback and climb up an increasingly steep slope. Cross over Main Street to start in on Lower Sidewinder. More steady climbing leads up through the switchbacks and loose rocks to intersect with 2-Stroke.

Keep left for a more gradual climb until you can turn right on Upper Sidewinder. This short and rocky trail is pretty level. Turn left onto Upper Backside for a moderate descent to Vista Ridge. A left, and another left will bring riders to Wades World. The traction is a little loose here and there are some short climbs to contend with.

At the next intersection, hang a right onto Ying for a fast rutted descent with sections of loose gravel to make things even more exciting. Hang a left on Main Street to traverse to the top of Lower Backside for a fast and fun descent that T's onto Out of Gas. Continue to the left to return to the parking area.

Intersection of Out of Gas and Lower Backside - the descent is definitely doable but recommend you scout your line first
