The Flagstaff Mountain and Chapman Drive Loop is a challenging touring cycling route that offers a fantastic mix of terrain and views right outside Boulder. You'll climb through shaded forests on the car-free Chapman Drive, passing historic 1930s-era Civilian Conservation Corps stone bridges, before hitting the paved Flagstaff Road with its sweeping panoramic vistas of the Rockies and the Boulder Valley. This difficult 12.4-mile (20.0 km) loop involves a significant 1544 feet (471 metres) of elevation gain, typically taking around 1 hours and 42 minutes to complete.

To tackle this route, a gravel or mountain bike is your best bet, as the surfaces range from dirt and gravel fire road to paved mountain road and sections of the Boulder Creek Path. The loop is easily accessible from downtown Boulder, making it a popular choice for those seeking a substantial and rewarding climb. Be prepared for steep grades; Chapman Drive averages 7%, and Flagstaff Road has sections exceeding 15%, so good fitness is essential.

This loop is notable for its unique combination of a car-free dirt road ascent and a thrilling paved descent, all while being close to urban amenities. Keep an eye out for diverse wildlife like coyotes, foxes, and mule deer, and if you visit in late spring, you'll be treated to abundant wildflowers. It's a prime example of challenging bike rides Flagstaff Mountain offers, providing both a physical test and stunning natural beauty.

This is a nice packed dirt and gravel connector trail, with views of the range from South Bolder Peak to Green Mountain and the Flatirons. Best to avoid this track if there has been recent rain or snow.

The views from here are amazing. It shows just how wide and open Davidson Mesa Open Space is. It's a great place to stop for a pause.

An out-of-the way multi-use path running between the south edge of a golf course and an irrigation ditch. Makes you forget you are in the middle of a city.

Varsity Lake is a pretty small reservoir in Boulder, Colorado. You can ride over the lake on the Varsity Bridge, or you can circle around the water on one of the other paved paths.
