This is a brand-new singletrack built 2014 by Jefferson County on JeffCo/Private/Pike Forest land. This ride consists of long sustained climbs and downhills. It can be ridden as an out-n-back or as a lollipop when combining the trail with the offerings in Reynolds Park. You are constantly rewarded with great views of the South Platte Valley and Pike National Forest, as well as the sounds of the river below.

Need to Know

Use bug spray and long sleeves/arm/leg warmers to keep the vegetation from smacking you in the arms and legs. The growth in some areas has taken over the trail!


I found the best way to ride this trail is from the parking area at its lowest point - along the north fork of the South Platte River. By parking here you'll have driven past Reynolds Park which is the high point of the ride.

From the parking lot you'll start a mellow climb through scattered ponderosa pine and an abundance of pretty much every type of wildflower in the state (when I went early July). The trail is a rolling climb for the first 7 or so miles - a couple hundred ft. up, then 100ft down - you'll come to some doubletrack for about 1 mile then the trail branches back off and continues to climb. At approximately mile 8 you start a longer downhill into Reynolds Park. Continue to the intersection of Hummingbird Trail and take a left to start a fun and fast 1 mile descent to South Foxton Road.

Look for the rest of the Hummingbird Trail on the right. Climb this for about half a mile. You'll gain about 300ft. and at times you'll be pushing your bike as the trail hits over 33% grade. Once past the bench the trail flattens out and then you'll dive back onto the North Fork Trail. Now back on the North Fork Trail and heading back to your car, be sure to watch for hikers and other riders as you start bombing this perfectly cut - nearly rock free downhill.

Option: Once in Reynolds Park, doing Hummingbird Trail counter-clockwise will send you down the steep section but still requires to climb a steep trail to get back up.

Incredibly fun and mellow trail. Nothing too technical or steep until the loop at the end (which you can skip). Can't wait to ride it again. 18mi — 2h 30m

Nothing technical about this ride but the climb is long. Not Everyone in our group finished the climb. The ride back is very fun but lots of blind turns so be mindful for those coming up. There is not a ton of room so step off of the trail on a lot of the parts. Apr 17, 2017
Not technical by any stretch, but a good trail to work on cornering skills and handling loose surfaces. The faster you go, the harder this trail is, both on the up and downhill. Jun 26, 2017

6/8/18: Ignore the other comments and remarks...the ride is as described. Not sure what the previous folks were expecting....the description doesn't describe this as technical so I don't quite understand the disappointment of no jumps/rocks/technical. If you like single track and climbing this is your ride. Ride it as Rx will be severely disappointed (and mad) if you start at the north parking lot because you will have to climb all the way back to the car. The views are exceptional and the sounds of nature are all over this ride. You will have time to hear them on the 8.0 mile climb..nothing to steep just continuous. Once you arrive at the upper parking lot and start back up on the Hummingbird Trail..this is STEEP...hike/bike but it isn't very long. Then you get a fast and fun downhill. It is very tight and the turns come up quick...make sure the brakes are working well. I enjoyed this ride for a lot of reasons: Views, trail conditions, very few hikers/bikes (in fact no one) and the reward of the downhill followed by a leg soak in the S. Platte River. Jun 8, 2018
