Old Fall River Road & Trail Ridge Road loop

The prime time for cycling the Old Fall River Road & Trail Ridge Road loop is typically from late May to early July. During this period, you might experience a unique car-free window on Old Fall River Road and sometimes sections of Trail Ridge Road, offering a serene experience without vehicle traffic. The roads usually open fully to cars after early July. Always check the latest road status with Rocky Mountain National Park before you go.

This loop offers a varied terrain. Old Fall River Road, which you'll typically ride uphill, is about 9-10 miles of narrow, one-way dirt/gravel with sharp switchbacks. While some road tires can manage, a gravel bike is often recommended for comfort. In contrast, Trail Ridge Road is a paved, two-way road in excellent condition. Overall, the loop is roughly 20% gravel and 80% paved.

No, this loop is considered a 'difficult' touring bicycle route, demanding 'very good fitness' and 'advanced riding skills.' You'll climb to elevations exceeding 12,000 feet, which means riding in oxygen-deprived conditions. It's not recommended for beginners or families with young children due to its significant elevation gain, challenging terrain, and unpredictable mountain weather.

Yes, you will need to pay an entrance fee to enter Rocky Mountain National Park. Additionally, during peak season (typically late May through mid-October), a timed entry permit may be required to access certain areas of the park, including the roads for this loop. It's crucial to check the official NPS website for the most current information on fees and timed entry requirements before your visit.

Common starting points with parking include the Estes Park area, which provides access to the eastern side of the loop. Specific parking areas within Rocky Mountain National Park can fill up quickly, especially during peak season. Consider arriving early in the morning to secure a spot. Always check the park's official website for current parking regulations and availability.

Mountain weather is highly unpredictable, even in summer. You should be prepared for rapid changes, including cold temperatures, gusty winds, thunderstorms, hail, and even snow. Essential gear includes extra layers, gloves, a wind jacket, leg warmers, and a thin thermal hat. A 1:1 low gear ratio is highly recommended for the steep ascents. Don't forget plenty of water and snacks.

The high altitudes and diverse ecosystems along the loop offer excellent opportunities for wildlife viewing. Keep an eye out for pikas, marmots, ptarmigans, bighorn sheep, elk, deer, and turkeys. Early in the season, you might also experience impressive snow walls lining the roads, adding to the unique scenery.

These include the Ute Trail, Little Horseshoe Park Trail, Tundra Communities Trail, Beaver Wetlands Boardwalk, Lawn Lake Trail, and Alpine Ridge Trail.

Key highlights include the historic Old Fall River Road with its switchbacks and the highest continuous paved road in the U.S., Trail Ridge Road.

The estimated duration for completing this challenging loop is around 4 hours and 8 minutes of pure riding time. However, due to the significant elevation gain, high altitude, and numerous scenic viewpoints, many cyclists plan for a longer day, often 6-8 hours, to account for breaks, photos, and acclimatization.
