Mountain Bike the Betasso Preserve

The Betasso Preserve features two loop trails that are accessible to both hikers and mountain bikers. 

Drive up (west) Boulder Canyon about 15 minutes outside of Boulder and turn right (north)  on Sugarloaf Dr.  After another 5 or so minutes you'll see a sign on the right-hand (northeast) side of the road that takes you to the Betasso parking lot. 

The Canyon Loop Trail is a moderate 3.3 mile trail with a gentle grade throughout. Enough uphill to get your heart pumping and downhill to whip your hair, but nothing extreme enough to be concerned about. 

The Benjamin Loop is 2.4 miles roundtrip and is equally appealing. There are some steep switchbacks on the connector trail, but the loop itself is a wide open, well-maintained trail with plenty of space for both hikers and bikers. 

Please note that bikes are prohibited on Wednesdays and Saturdays.
