Detour: Beginning March 2021, trail users will be directed to use a 1.1 mile on street detour from from South Sunset Street on the western end to Price Road. The detour is in place as part of a flood mitigation project and will remain until 2023. The route is clearly marked with signage to help users navigate around the work zone. For updates, please see the project website.
The St. Vrain Greenway begins in Golden Ponds Park and travels east along the creek for more than half its distance. At the park, watch for the bald eagles, wood ducks, great blue herons and Canada geese that call the area home. The trail skirts commercial and residential areas through the heart of Longmont, offering spectacular mountain scenery along the way and lake views by the Boulder County Fairgrounds and Izaak Walton Park.
Shortly after reaching Ken Pratt Boulevard (State Route 119), its character changes, opening up to rural countryside. It's near this intersection that you can hop on the Left Hand Greenway and ultimately the Longmont-to-Boulder Regional Trail, which connects two cities and a vast trail network.
The St. Vrain Greenway ends at Sandstone Ranch Park, which features a homestead built in the early 1880s by a Gold Rush pioneer. The 313-acre park offers a playground, picnic area, skatepark and ball fields.
Parking is available on the trail's western end at Golden Ponds Park, one block west of Hover Road and Third Avenue. On its eastern end, parking can be found at Sandstone Ranch Park and, mid-trail, at the Boulder County Fairgrounds and Izaak Walton Park.
