Berthoud Pass

You can access the route from either Empire (south side) or Winter Park (north side). Parking is generally available at the base of the pass on both sides. As a major commercial route, US 40 carries consistent traffic, so look for designated parking areas that allow safe access to the wide shoulders.

While it involves significant elevation gain and traverses the Continental Divide, the grades on this pass are generally considered manageable for a Colorado pass, rarely exceeding 5.5% on the Empire side. The wide, well-maintained roads and shoulders also contribute to a safer experience, making it suitable for beginners looking for a challenging but not overly steep climb.

The best time to cycle this route is typically from late spring through early fall, once the snow has melted and before winter conditions set in. Waterfalls can be seen flowing late into the summer, adding to the scenic beauty. Always check local weather conditions before heading out, as high-altitude weather can change rapidly.

This route primarily follows US Highway 40, a paved road. While dogs are generally allowed in vehicles on the pass, bringing them along for road cycling can be challenging due to traffic and the nature of the ride. If you plan to stop at viewpoints or explore nearby trails, always keep your dog on a leash and adhere to any specific regulations for the surrounding areas, especially within the James Peak Protection Area.

No specific permit or entrance fee is required to cycle the Berthoud Pass road itself, as it follows US Highway 40. However, if you plan to venture off the main road onto trails within the James Peak Protection Area, it's always wise to check with the local Forest Service office for any specific regulations or permits that might apply to those particular trails or activities.

You'll be treated to breathtaking alpine panoramas almost the entire way. The route offers frequent and unobstructed views of surrounding valleys, craggy peaks, and towering pine trees. Views of the Continental Divide are prominent, and on clear days, the Indian Peaks are visible. The highlight of the route is the Berthoud Pass summit itself, offering expansive vistas.

The full route, covering approximately 35.7 kilometers (22.2 miles) with over 800 meters (2,600 feet) of elevation gain, typically takes around 2 hours and 25 minutes to complete for a racebike. This duration can vary significantly based on your fitness level, the number of stops you make, and whether you're cycling the full out-and-back or a point-to-point section.

Yes, while primarily a road cycling route, it does pass near or briefly intersect with sections of several other trails. These include the Fraser River Trail, CDT - Colorado Section, Second Creek Trail, Discovery Trail, Challenger Trail, Berthoud Pass West Trail, Mount Flora Trail, and Mines Peak Road. These are mostly short overlaps or adjacent sections, offering potential for multi-sport exploration if you're prepared.

Substantial road works over the years have resulted in wide roads with good pavement, which significantly enhances the cycling experience. A wide shoulder is present for much of the route, providing a safer space for cyclists amidst the consistent traffic, which includes cars, trucks, and 18-wheelers, as it's a major commercial route.

Yes, the town of Winter Park, located at the northern end of the route, offers a variety of cafes, restaurants, and accommodation options. Empire, at the southern end, also has some services. These towns provide excellent opportunities for refueling and resting before or after your ride.

The main challenge is sharing the road with consistent vehicle traffic, including large commercial trucks, as US 40 is a major thoroughfare. The insider tip is to utilize the wide shoulders provided and be highly aware of your surroundings, especially on descents and through switchbacks. Starting early in the morning can sometimes offer slightly less traffic, though it remains a busy road.
