Heil Valley Ranch is one of the popular Boulder-area trail systems, and this ride is the most commonly ridden section of trail, covering the Wapiti Trail
and Ponderosa Loop
These trails were the original mountain biking trails at Heil, but others have since been added, including the Picture Rock
trail that now makes it possible to ride from Heil Valley Ranch to Hall Ranch
It's not the best ride in the area, but it's a solid trail with a moderate climb, mostly straightforward intermediate terrain, and a few additional obstacles, plus a fast descent back to the trailhead to keep advanced riders entertained.
This trail climbs, mostly gradually, right from the trailhead. You'll start out on a rough dirt road, but don't worry - the singletrack starts just up ahead.
Once you hit the singletrack, it's a steady climb for about 2.5 miles, all the way up to the junction with the Ponderosa Loop
. The trail mostly runs through a heavily forested area, so there's plenty of shade. You're likely to see deer or other wildlife along the trail - maybe even a black bear.
The area is extremely rocky, but the Boulder Mountainbike Alliance and others have done much work to clean up the trail, make it flow better, smooth out the rocks, and keep it sustainable.
Eventually, you'll hit the junction with the Ponderosa Loop
, marked with a wooden signpost. Here, you can continue straight to ride the loop counter-clockwise, or make a left. It doesn't matter which direction you choose - either way, you'll find yourself rolling trail, with many rocks, some loose, along the way. The trail is still intermediate here, but pay attention - the loose rocks can throw you off your line.
Halfway around the loop you'll find a scenic overlook with a park bench - perfect for a breather and a snack. The overlook provides a far away view of Hall Ranch
below - which you can ride to by joining up with the Picture Rock
Also along the Ponderosa loop are turnoffs for the Wild Turkey trail, which then leads to the Picture Rock
trail, which can be ridden to Lyons and Hall Ranch
Once you complete your loop up top, you'll head down the way you came. It can be a fast descent if you let go of your brakes, and trail improvements over the past couple of years have made this a nice flowy descent. It's still rocky though, and you might feel like you should check all the fasteners on your bike when you reach the bottom!
Watch out for riders and hikers coming uphill. This is a popular trail, and you'll likely have to stop to yield at least a few times on the way down.
The 5200 acre open space making up Heil Ranch trails and the newer Picture Rock
trail are part of a large land purchase made by Boulder County Parks and Open Space in 1993 and 1994. The area housed large quarry operations from the 1890's to the 1960's.
