Hiking
The Saint Vrain Greenway offers a remarkably diverse hiking experience, winding through Longmont's varied landscapes. You'll traverse mostly flat, paved paths alongside the Saint Vrain Creek, enjoying river views and passing by serene spots like the Saint Vrain Waterfall. The trail also features gravel sections and nature paths, providing a mix of surfaces and scenery that transitions from urban parks to open countryside, often with mountain backdrops. Keep an eye out for local wildlife, including various bird species, as you explore this extensive route.
Planning your visit is straightforward, with numerous access points and amenities along the way. You'll find multiple parking areas, restrooms, and water fountains at the parks connected by the Greenway. The trail is generally accessible year-round, though spring and early summer can be particularly pleasant for spotting wildflowers. Remember that while much of the route is dog-friendly, specific sections have restrictions to protect sensitive wildlife habitats, so check local signage.
This extensive greenway is considered the "crown jewel" of Longmont's trail system, linking several parks, schools, and commercial areas. It's also a vital part of the larger Front Range Trail plan, aiming to connect Wyoming to New Mexico. The 26.8-mile (43.1 km) route, with its 341 feet (104 metres) of elevation gain, is rated difficult due to its length, taking approximately 10 hours and 56 minutes to complete, but its generally flat terrain makes it suitable for long, easygoing days.
