st vrain greenway in Longmont

Greenways and Trails


In September 2013, Longmont experienced the most devastating flash flood event in its history. The flooding caused extensive damage throughout Longmont. Many of our greenways and trails were impacted. Greenways most significantly affected were St. Vrain, Left Hand Creek, and Lykins Gulch.

Please be sure to review the most up-to-date closure information due to flood damage and repair activities, found on the City's flood information website:


For residents of Longmont and those in surrounding areas, a greenway serves as a sanctuary - an oasis from the noise and pace of everyday life. Weaving through parks and alongside rivers, creeks, ditches, and lakes, they protect neighboring wildlife areas yet provide opportunities for both environmental and recreational activities. They also serve as maintenance access for storm drainage functions throughout our City.

"The trails become a part of the natural surrounding while maintaining and enhancing the natural character of the river corridor. A true escape." ~ City Forester, Kenneth Wicklund

Dry Creek Greenway

The Dry Creek Greenway runs west from Willow Farm Park (at Fordham Street) to Grand View Meadows Drive (near Silver Creek High School). Further west, the trail runs from Blue Skies Park to North 75th Street. As development continues, the Greenway will link the two existing trail segments within Dry Creek Community park (west of Grandview Meadows Drive and east of Mountain Drive). This greenway will eventually connect to Twin Peaks Mall at Hover Street. Other facilities found along this greenway include: Eagle Crest Elementary School, Altona Middle School, Silver Creek High School and Blue Mountain Elementary School. Dry Creek greenway opens to several detention pond sites that are also part of the Longmont park system.

Left Hand Greenway

The Left Hand Greenway trail is in place from the St. Vrain River to Hover Street. The trail connects to Quail Campus (Longmont Recreation Center and Museum/ Cultural Center); Kanemoto Park and Lefthand Creek Park - all along Lefthand Creek. Named after Chief Niwot (translated as "lefthand" from the Arapaho language), the creek flows from Lefthand Canyon through south Longmont, where mature willow and cottonwood trees grace its banks.

Longmont Supply

The Longmont Supply Greenway begins at the intersection of 17th Avenue and Cambridge Drive and runs south to Hover Acres Park. Water flows from the Longmont supply Equalizer Pond off 21st Avenue into the ditch. Meandering through residential neighborhoods, the Longmont Supply Greenway is a good jogging and walking path.

Lykins Gulch

Lykins Gulch Greenway begins at Golden Ponds just south of the St Vrain Greenway bridge and runs to and under Airport Road. This one mile long greenway generally follows the historic alignment of the gulch and has been recreated primarily for storm water management. Newly created wetlands border the channel with ponds visible on both sides of the trail (PRIVATE OUTSIDE of Golden Ponds - no public access!). A boulder crossing of the gulch connects to the gravel trail around the south pond at Golden Ponds. The Lykins Gulch greenway provides a good pedestrian and bicycling route between the St Vrain Greenway and Golden Ponds to southwest Longmont.

Oligarchy Greenway

The Oligarchy Greenway is developed along part of the Oligarchy Ditch which runs through Longmont from McIntosh Lake (at the western end) to Union Reservoir (at the eastern end). The Oligarchy Ditch takes its name from the way most ditch companies were structured; "Oligarchy" means "government by the few." It is one of the earliest ditches built for Longmont's farmers and is considered an historic site. To date, the greenway exists from McIntosh Lake (at Airport Road in the Shores neighborhood) to Garden Acres Park, and again from Mountain View Avenue (just west of Lashley Street) to Third Avenue (near Pace Street). Features found along this trail system include McIntosh Lake District Park, Boulder County Lohr Agricultural Heritage Center (off Highway 66), Flanders Park, Dawson Park, Garden Acres Park, Clark Centennial Park and Rothrock Dell Park.

Rough and Ready

The Rough & Ready Greenway runs from Highway 66 to near 9th Avenue at Pace Street along the Rough and Ready Ditch. This trail connects to Rough and Ready Park, Alpine Elementary School, Skyline High School and runs near to the Ute Creek Golf Course.

Trail lengths to various landmarks (shown in miles):

St. Vrain Greenway

This trail system is considered the 'crown jewel' of Longmont's trail system as it links a variety of parks (gems), schools, other trails and commercial areas along its length (this concept in park design was first popularized by Frederick Law Olmstead who designed New York's Central Park, Boston's Emerald Necklace, and the Washington Monument). Currently the trail runs from Golden Ponds (at 3rd Avenue west of Hover Street) to Sandstone Ranch (approximately 8 miles). 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!

St Vrain trail with visitor on bench

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 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 (and to the newly acquired Boulder Creek Estates property - Longmont's first Open Space purchase). Boulder County plans to continue the Greenway west to Lyons and Colorado State Parks will extend the trail through St. Vrain State Parks to link to the Town of Frederick trail system.

The greenway promotes conservation awareness, improves habitat wildlife, and provides a variety of recreational opportunities. The Colorado Lottery has been the City's primary funding source for this important project. Boulder County has provided land and funding for portions of the Greenway, with Great Outdoors Colorado, and the Division of Wildlife allocating grants. Private donors have also contributed to the Greenway, including the Kanemoto Family, V.V. Golden Foundation, The St. Vrain Valley Foundation and the Roger and Roberta Jones Foundation. 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, Rogers Grove, Boulder County Fairgrounds, Izaak Walton Pond, Sandstone Ranch, and a future district park site just east of Main Street (currently referred to as Dickens Park). The trail connects to the Lefthand Greenway just east of Main Street. Future plans call for a connection to Union Reservoir and eastern Longmont via Spring Gulch #2.

Existing trailheads can be found at Golden Ponds, Rogers Grove, Boulder County Fairgrounds, Izaak Walton Pond, the sundial area at South Pratt Parkway, at 1st Avenue near the Fire Training Center (west of Martin Street), the western end of the Harvest Junction North commercial development and at Sandstone Ranch.

Future St. Vrain Greenway Development

St. Vrain Greenway trail system was fully constructed from Golden Ponds to Sandstone Ranch. A future project will extend the trail west to Pella Ponds in the town of Hygiene. Another future project will extend the trail east to St. Vrain State Park. Current priority is to rebuild the pre-flood 8 mile trail and then resume work on the trail extensions.

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 the river engineering project that will reduce the floodplain area along the river corridor. For information on this study, please visit

Dog Restrictions on St. Vrain Greenway East of County Line Road

The St. Vrain Greenway trail east of County Line Road has dog restrictions adopted by City Ordinance. Dogs will not be allowed on the portion of the trail east of County Line Road to Sandstone Ranch (pdf map of area) (approximately one mile of trail), on a leash or unleashed. Not able to recognize restraints such as leashes, wildlife views all dogs as predators and will leave the area. The Longmont City Council directed the restriction to protect this unique landscape, the wildlife in this area and its important wildlife habitats. When the trail is open, the approximately six miles of the St. Vrain Greenway trail from County Line Road west to Golden Ponds will be available to people and their leashed dogs.

Currently, Ute Creek Golf Course, Fall River Elementary School, Stephen Day Park and Trail Ridge Middle School can be found along the trail.
