Description

This 29.2-mile (47.0 km) loop packs in 3015 feet (919 metres) of elevation gain, taking around 4 hours and 16 minutes to complete.

What to expect on Nederland – Barker Reservoir Road (paved) loop from Nederland

Expect a demanding journey as you climb towards Barker Reservoir, primarily via Boulder Canyon Drive. The route offers stunning mountain vistas and follows Boulder Creek for a portion of the ascent, providing a scenic backdrop to your effort. While the road surface is generally paved, be aware that sections of Boulder Canyon Drive can be narrow, twisting, and heavily trafficked, sometimes without a dedicated shoulder. Upon reaching Barker Reservoir, you'll be rewarded with expansive views of the wide lake and its forested shores, a perfect spot to pause and appreciate the climb.

Planning your visit

This route is considered difficult due to its substantial elevation gain. For parts of the Boulder Canyon climb, you might find the Boulder Creek Path to be a useful alternative to the main road, offering a mix of concrete and finely-crushed gravel. Cyclists should be prepared for potential rocks in the road on Boulder Canyon Drive. Given the traffic and challenging nature, it's wise to plan your ride during off-peak hours or seasons if possible to enjoy the scenery more peacefully.
