Longmont-to-Boulder (LOBO) Regional Trail

The full 43 km (26.7 miles) route, which connects Longmont and Boulder, typically takes around 2 hours and 40 minutes to complete by touring bicycle. This duration can vary based on your pace and any stops you make along the way.

The trail features a mixed-surface terrain. You'll encounter primarily hard-packed crushed stone, but also sections of asphalt and concrete. For touring cyclists, especially with loaded panniers, wider tires (32mm to 47mm) are recommended for comfort and stability on the crushed stone segments.

The trail is generally considered a moderate ride. While some sections are flat and open, others include gentle hills and unpaved segments that might be moderately challenging. It's a good option for those with good fitness, but be prepared for mixed surfaces and some on-road connections where you'll share the road with traffic.

You'll experience diverse scenery, including rural landscapes, open fields, and views of distant mountains. Notable spots include the Great views of the Foothills, especially from the Twin Lakes area, and the Twin Lakes themselves. You'll also pass by the Cottonwood Trail section.

Dogs must be on a leash at all times, and you are required to clean up after your pet. Always check specific signage, especially in sensitive wildlife areas.

Spring and fall generally offer the most pleasant cycling conditions with mild temperatures and beautiful scenery. Summer can be hot, so starting early in the morning is advisable. Winter cycling is possible, but be prepared for colder temperatures and potential snow or ice on sections of the trail.

You can find parking at various trailheads along the route. Notable trailheads with parking include Lefthand Valley Grange Trailhead and Niwot Trailhead. Keep in mind that restrooms at some trailheads, like Niwot, may be seasonal. For access from Boulder, look for parking options near the trail's western terminus.

No, there are no specific permits or entrance fees required to use the LOBO Regional Trail itself. It is part of the public trail system. However, if you venture into specific Boulder Open Space and Mountain Parks areas off the main trail, always be aware of any posted regulations or potential permit requirements for certain activities, though this is rare for general trail use.

While dedicated repair stations or frequent water fountains are not explicitly detailed directly on the trail, restrooms are available seasonally at some trailheads, such as Lefthand Valley Grange Trailhead and Niwot Trailhead. The trail's proximity to Longmont and Boulder means you can find opportunities for refreshments and supplies in nearby towns and commercial areas.

The trail includes several areas where you'll need to use on-street connections to link different segments. For example, a short on-road route connects the trail at Spine Road to the Cottonwood Trail on Jay Road. Jay Road is a heavily trafficked bicycle route. Touring cyclists should be comfortable riding in traffic and aware of vehicle speeds in these sections.
