NOTE: The St. Vrain Greenway east of County Line Road has dog restrictions adopted by City Ordinance. Dogs will not be allowed (leashed or unleashed) on the portion of the trail east of County Line Road to Sandstone Ranch (approximately one 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. Follow the St. Vrain River through the heart of Longmont as you pass a cheese importer and microbrewery along the way. Starting at the beautiful Sandstone Ranch, the St. Vrain Greenway takes you all the way through Longmont from east of town to the Golden Ponds on the west side. The trail is quite level and all road crossings are below-grade, so it is extremely safe. Other than the first mile, where dogs are banned to protect the wildlife, the trail is dog-friendly, family-friendly, and handicapped accessible. It is also wonderful for alternative wheeled transportation such as inline skates, recumbents, Trikkes, and Elliptigos. In addition to being a wonderful hiking or biking trail, it also offers excellent diversions including the Cheese Importer and Left Hand Brewing Company microbrewery located just off the trail. Trail explorers will also enjoy numerous parks, delicious restaurants, and a handful of historical sites including the Sandstone Ranch historic homestead at the very beginning of the eastern trailhead. Many local residents don't even know this historical treasure even exists so close to their home. It is a very peaceful and scenic location replete with historical information, gorgeous views, and an abundance of prairie wildlife.

This is a fun run, though I've never done the east end beyond 119. Running through Longmont, you'll pass a number of bodies of water, decent shade, and the St. Vrain. Some of the trail to the near west of Main St. is not repaired. This is a must-do trail if you are visiting Longmont.

Nice local trail, the river and trail have moved from how they are marked on the app after the 2013 flood.

One of the best places for a leisurely bike ride in Longmont. Not many people. It passes right by Golden Ponds, so that is a fun detour. On a still day, the ponds photograph really well with Longs Peak towering in the distance. The long stretches at the eastern end, right before the Weld County side, can be quite exposed and intimidating in the summer heat.

This is a great paved trail for biking or walking next to the St Vrain River. It obtained extensive damage during the floods but it's almost completely repaired. The last couple of miles are still not open. I like riding there when Im not looking for anything strenuous.

Dogs are allowed there. Perhaps not off leash??

Sadly the St Vrain Greenway was destroyed in the September 2013 flood, only small sections are open. Twenty years in the making destroyed in a flash.
