The St. Vrain Greenway is Longmont's trail backbone, following St. Vrain Creek through the city and connecting parks, neighborhoods, and open spaces. The paved multi-use path offers easy walking and biking with creek views and wildlife sightings. It's the best way to experience Longmont's commitment to outdoor access.
The Trail System
The greenway runs roughly east-west through Longmont, with spurs and connections to parks along the way. The main trail is paved and suitable for all users - walkers, runners, cyclists, and families with strollers.
Key sections:
- Western stretch through open space with mountain views
- Central section near downtown and the Longmont Museum
- Eastern section connecting to Golden Ponds and Union Reservoir
The trail connects to Longmont's broader trail network, making it possible to create loops or extend your distance.
Along the Way
Creek Views: St. Vrain Creek provides the constant companion. The cottonwood-lined corridor offers shade in summer and fall colors in autumn.
Wildlife: Expect to see birds, rabbits, and occasionally deer. The creek corridor is a wildlife highway through the urban area.
Parks: Multiple parks along the greenway offer restrooms, playgrounds, and picnic areas. Good stopping points for families.
Art: Public art installations appear along sections of the trail, part of Longmont's public art program.
Access Points
Multiple trailheads and park access points make it easy to join the greenway:
- Golden Ponds - eastern access with parking and facilities

Using the Trail
Biking: The paved surface is ideal for road bikes and hybrids. The flat terrain makes for easy riding. Watch for pedestrians and announce when passing.
Walking/Running: Stay to the right, especially in busier sections. The surface is comfortable for all footwear.
Dogs: Welcome on leash. Clean up after your pet - bags and trash cans available at trailheads.
Best times: Early morning and evening for cooler temperatures and wildlife. Weekdays are less crowded than weekends.
2013 Flood Recovery
The St. Vrain corridor was heavily damaged in the September 2013 floods that devastated much of the Front Range. The greenway has been rebuilt with improved flood resilience, and the recovery process created opportunities to enhance the trail system. The restoration represents significant community investment in this public resource.
