Trail shared by Matt L with improvements by Rob Stahl

A fantastic lollipop in the mid-valley that mixes a little bike path with lots of flowy singletrack.

Please be aware of seasonal closures on the Crown and Rio Grande Trail. Trail cameras are in use and violations are reported. Rio Grande - Rock Bottom Ranch to Catherine Store segment is seasonally closed Dec. 1 – April 30. Glassier Open Space is seasonal closed from Dec. 1 – May 15.


A great loop that can be accessed from Catherine's Store Road or Hook Spur Lane that provides an easy climb, ample flow, and a fun descent. Rides well in either direction!


This is a great ride that combines two fairly new trails in the mid-valley that make for a great after work excursion. The ride starts and ends from the Catherine's Store Parking Trailhead along the Rio Grande Trail. Alternatively this ride can be started from the Hook Spur Parking Trailhead along the Rio Grande near Willits Lane (to spend less time on the paved bike path).

From either location, expect a moderate climb up the Glassier OS Trail before a fun and flowy traverse across Buckhorn Traverse punctuated with a ripping descent down the lower half of Buckhorn. It's worth noting that this loop is completely rideable and fun in both directions. However, the Buckhorn Traverse flows better in the downvalley direction. In either direction you'll end your ride descending either Buckhorn or Glassier OS Trail and you'll be smiling all the way home.

History & Background

The Glassier OS Trail and lower Buckhorn were completed in 2016. They were connected by the Buckhorn Traverse in 2017.
