A fun series of trails East of town with expansive views of the front range. This is a good trail for the whole family - it's mostly mellow and flat with some dirt road, some doubletrack, and some singletrack. There's even a short intermediate section with a steep climb and a few small steps thrown in to keep it interesting for more advanced riders.

Need to Know

There are a few different access points for this ride, so you don't have to start at the trailhead off Arapahoe Rd. You can also park along Valmont Rd, or start in the Heatherwood neighborhood at Gunbarrel Farm.

Lots of people come here to walk their dogs, so be prepared to slow down or stop. Be courteous - this is definitely a family trail system and not a hardcore MTB ride.


Starting from the Teller Farm trailhead, you'll head generally North. The trail is flat to slightly downhill and wide - almost a dirt road. Teller Farm is a working farm - you'll often pass cattle grazing as you ride towards the trailhead on Valmont Rd.

Once you reach Valmont Rd., you'll cross the road heading North, and pickup the White Rocks section of trail. The first part of the trail winds past a couple of large ponds that were once gravel pits mined by the Flatirons Company. The ponds are now very scenic, with the foothills in the background to the West.

You'll then cross over Boulder Creek on a large wooden bridge (another scenic spot to relax) and head up the only semi-technical section of trail.

The trail continues uphill until it crosses a small residential road (W Phillips Rd.) and then heads West for a bit with grassy fields to the north and south. Eventually, the trail makes a sharp turn northward, then winds around gradually to the west and climbs to a big water tower overlooking Gunbarrel Farm and the residential communities there.

Take a moment to enjoy the expansive front range views here before descending the doubletrack down to the Gunbarrel Farm trailhead in the Heatherwood neighborhood.

Finally, turn around and re-trace your route back to where you started from.

History & Background

Teller Farm is an historic and working farm. The ponds in the White Rocks section of trail were once gravel pits that have been mined and reclaimed by the Flatirons Company.

Looking down part of the White Rocks section of the East Boulder Trail.  Easy riding in the hilly plains east of town.

Nice trail, fewer walkers up near the north end. The hill in the middle (traveling S to N) was pretty sustained. 15mi — 1h 30m

Dry and sandy in spots. Right after Valmont where it goes to singletrack, really sandy.
