Betasso Wildlife Preserve is great local mountain bike locale in Boulder not only because of its spectacular views and opportunities to see wildlife, but also because it can be ridden to directly from town. In the late 19th century the area had been used for mining operations and the Betasso family cattle ranch, but it has since been generously transformed into a Boulder County Open Space for all to enjoy. The Betasso family cabin from the early 1900s still stands in its original location. Albert's squirrels, woodpecker, bears, and mountain lions flourish here, so keep your eyes peeled and bring a camera.
The loops here are meant to be ridden only one-way, so pay attention to which direction you're traveling. The trails are closed to mountain bikes on Wednesdays and Saturdays. Beginning your ride from the parking lot, the trail flows through pine forests and alpine meadows with blazingly fast singletrack. Riders of all skill levels will enjoy devouring the trails here, as the uphill climbs are short and only a minimal amount of pedaling is required. Watch out for other riders who are out furiously pumping this trail, as it can get very busy in the evenings and weekends. This Betasso Preserve Loop is a great introductory ride to all the trails that Boulder has to offer.
