St. Vrain Greenway
Longmont, CO n/a
- Trails (Concrete and Gravel)
In September 2013, Longmont experienced the most devastating flash flood event in its history. The flooding caused extensive damage throughout Longmont. The St. Vrain Greenway was significantly impacted. Repairs have been made to many sections. The remaining damaged portions are being reconstructed through work on the Resilient St. Vrain project.
- The portion running from Main Street Bridge east to Sandstone Ranch Nature Area has been restored. This trail is now reopened for public use.
- The southeast side of Golden Ponds is anticipated to open in late summer after spillway replacement has been completed.
Please be sure to review the most up-to-date information on trail closures on the Trail Status Map.
This greenway is considered the 'crown jewel' of Longmont's trail system as it links a variety of parks, schools, other trails and commercial areas along its length.
Currently the trail runs approximately 8 miles from Golden Ponds (at Third Avenue, west of Hover Street) to Sandstone Ranch. The St. Vrain Greenway is part of the Front Range Trail plan--a regional trail system that will some day run from Wyoming to New Mexico.
Many miles of concrete bike paths and gravel walking paths, as well as nature trails, welcome visitors of all kinds to the Greenway. Several other city parks abut the Greenway, including Golden Ponds, Roger's Grove, Izaak Walton Pond, Sandstone Ranch Nature Area, and the future Dickens Farm Nature Area (just east of Main Street). The trail also connects to Left Hand Greenway.
Existing trailheads can be found at Golden Ponds, Roger's Grove, Boulder County Fairgrounds, Izaak Walton Pond, South Pratt Parkway, the western end of the Harvest Junction North commercial development, 119th Street, and at Sandstone Ranch.
Dog Restrictions on St. Vrain Greenway East of County Line Road
The St. Vrain Greenway east of County Line Road has dog restrictions adopted by City Ordinance. Dogs are not allowed (leashed or unleashed) on the portion of the trail east of County Line Trailhead to Sandstone Ranch (approximately 1 mile of trail). Dogs pose a threat to wildlife in this area. City Council directed the restriction to protect this unique landscape, the wildlife in this area, and its important wildlife habitats.

Future St. Vrain Greenway Development
The original master plan for the St. Vrain Greenway was completed in 1992 calling for seven miles of trail corridor from North 75th Street to County Line Road (County Road 1). An eastern corridor master plan update was adopted July 2001 for the portion of the St. Vrain Greenway corridor west of Main Street, and extended the original corridor from Weld County Road 1 to Weld County Road 7. Plans call for connections to Union Reservoir and Spring Gulch #2.
Boulder County plans to eventually continue the St. Vrain Greenway west to Lyons, and Colorado State Parks hopes to extend it through St. Vrain State Park to link with the Town of Frederick's trail system.
NOTE: Current priority is to rebuild the pre-flood, 8-mile trail and then resume work on extensions.
St. Vrain Blueprint
The St. Vrain Blueprint is a redevelopment study underway to explore and develop a vision for special public places along the St. Vrain Greenway in coordination with Resilient St. Vrain, Longmont's extensive, multi-year project to protect people, property and infrastructure by improving the creek channel and reducing the size of the floodplain through Longmont.
