This is a 16 mile loop around some Boulder County Open Space with great views towards the mountains. It is classified as an easy/intermediate trail by the MTB Project. There are about 10 miles of single track and 6 miles of double track that is either gravel bike path or old dirt road. There are a couple of short sections that are somewhat technical but are very rideable or there an easy walk around for anyone that does not want to ride them. This is a relatively long ride so we'll likely take around 3 hours to do it, including some stops. There is not much shade on this ride so bring plenty of water in case we get some hot temperatures.

*This is a Bobcat trip. The Bobcats mission is to ensure a variety of challenging CMC trips, especially “B Difficult” and “C” hikes and Difficult Snowshoes, for our mostly age-50+ constituents.  Although we have members, our trips are non-exclusive.  We welcome all CMC members to sign up for any Bobcats trip regardless of age or Bobcats membership. To join our mailing list, write or call CMC Membership Services at: or (303) 279-3080.


A mountain bike is needed for this trail. This is not a technical singletrack so knee and elbow pads are not needed but you are welcome to wear them for extra protection against falls. Let the trip leader know if you have any medical or other issues that they should be made aware of. Bring plenty of water and some snacks. I'll email everyone the day before the trip to update on weather conditions.


Sorry it is past the registration deadline for this event.
