Frequently Asked Questions

Where can I park to access the Lefthand Canyon Trail for cycling?

The Lefthand Canyon Trail is primarily a road cycling route, so you can typically find parking at various points along the canyon road, especially closer to Boulder. Many cyclists start from Boulder itself and ride into the canyon. Be mindful of local parking regulations.

Is the Lefthand Canyon Trail suitable for beginner touring cyclists?

The paved Lefthand Canyon Road offers a long but generally mild climb, making it accessible for cyclists with good fitness. While the initial sections are easier, the climb becomes more sustained with segments reaching up to 8.5% gradient. It's considered a moderate difficulty ride for touring cyclists, so beginners should be prepared for a significant elevation gain.

What is the terrain like for touring cyclists on this route?

The primary route for touring cyclists is a well-maintained, paved road that gradually ascends through the canyon. It follows Lefthand Creek, winding through tree-covered mountains and Ponderosa pine forests. While the road is excellent for touring bikes, it's important to note that dedicated mountain biking trails in the Lefthand Canyon OHV area are much more technical and unsuitable for typical touring bicycles.

What are some notable sights or stops along the Lefthand Canyon Trail?

As you cycle, you'll pass through the scenic Lefthand Canyon itself. The historic town of Ward, located at higher elevations, is a common turnaround point and offers a cyclist-friendly general store. You might also spot a historic jeep wreck. For refreshments, consider stopping at the Jamestown Mercantile Café or enjoying the facilities at Jamestown Park.

Is the Lefthand Canyon Trail dog-friendly for cyclists?

While the paved road is a public thoroughfare, specific regulations for dogs may vary depending on where you stop or if you venture onto adjacent trails. Generally, dogs should be leashed and under control. Always check local signage for the most current rules, especially within the Arapaho and Roosevelt National Forest.

What is the best time of year to cycle the Lefthand Canyon Trail?

The best time to cycle this route is typically from late spring through early fall (May to October) when the weather is mild and the roads are clear of snow and ice. The scenery is particularly beautiful during these months, with vibrant foliage in the fall. Always check weather conditions before heading out, as mountain weather can change rapidly.

Are there any permits or entrance fees required to cycle the Lefthand Canyon Trail?

No specific permits or entrance fees are required to cycle the main paved Lefthand Canyon Road. This route passes through parts of the Arapaho and Roosevelt National Forest, but the road itself is publicly accessible. If you continue beyond Ward to the Brainard Lake Recreation Area, there was no toll for cyclists as of 2020, but it's always good to check for any updated regulations.

Does the Lefthand Canyon Trail connect with other cycling paths?

Yes, while primarily a standalone route, the area offers various options. The route itself covers sections of the Left Hand OHV Trails, Left Hand Main Trail, Canyon Rim Trail, and Bon Scott Trail. Cyclists often combine the canyon ride with other scenic roads in the Boulder area, such as Lee Hill Drive, to create longer loops.

Are there places to refuel or get refreshments along the route?

Yes, the small town of Ward, a common turnaround point for many cyclists, has the Utica Street Market, which is known to be cyclist-friendly and a great spot for snacks and refreshments. Additionally, the Jamestown Mercantile Café is another option along the way.

What should I be aware of regarding traffic and safety on the Lefthand Canyon Trail?

While the road is popular with cyclists, traffic can be present, especially in the first few miles from Boulder, where cars may travel at 50 mph with no shoulder. Traffic tends to be milder as you climb higher. During descents, be aware of deer and other wildlife, as well as vehicles. The descent is described as 'super fun,' but requires vigilance.

Is the Lefthand Canyon Trail a loop or an out-and-back route?

The most common way to experience the Lefthand Canyon Trail for touring cyclists is as an out-and-back route, climbing up the canyon and then enjoying a fast descent back down. However, many cyclists incorporate it into larger loop routes by connecting with other roads in the Boulder area.

What kind of views can I expect while cycling Lefthand Canyon?

The route offers stunning scenery, starting with tree-covered mountains and dense Ponderosa pine forests. As you gain elevation, you'll be treated to increasingly expansive views of the often-snowcapped Indian Peaks. If you continue towards Brainard Lake, you can enjoy spectacular panoramic views that may include the distant Continental Divide.
