Boulder Canyon Drive

Prepare for a difficult road cycling adventure on the Ward via Lee Hill, the Peak to Peak Highway, and Boulder Canyon loop. This route spans 47.5 miles (76.5 km) and demands a significant 5389 feet (1643 metres) of elevation gain, typically taking around 4 hours and 52 minutes to complete. You will experience the demanding climbs of Lee Hill Drive, leading you towards the high-altitude stretches of the Peak to Peak Highway. As you pedal, look out for the dramatic rocky canyon walls and distant snow-capped peaks that define the Colorado landscape. The journey also includes a scenic descent alongside Boulder Creek through Boulder Canyon, providing a rewarding contrast to the earlier ascents.

When planning your ride, be aware that while much of the route is paved, you might encounter some unpaved sections that add to the challenge. Boulder Canyon, in particular, can become quite busy with vehicle traffic and has narrow shoulders, so starting your ride early in the morning is often recommended to avoid congestion. You will find opportunities to resupply with food and water in the small towns of Ward and Nederland, which are conveniently located along the way. Always check local conditions before heading out, especially regarding road closures or weather changes.
