This segment is considered difficult for jogging. It features constant elevation changes, often described as 'rollers,' meaning your legs will rarely get a break. With significant climbs and descents, rocky sections, and high-altitude exposure, it's best suited for experienced trail runners or hikers rather than casual joggers.
You'll encounter diverse and challenging terrain. Expect steep ascents and descents, rocky patches, and potentially marshy or muddy areas. A notable 3.3-mile stretch called the Snow Mesa is largely flat but very exposed and above treeline, offering no shelter from the elements.
The segment runs between San Luis Pass and Spring Creek Pass. Accessing the trailhead at San Luis Pass can be difficult, sometimes requiring a 4x4 vehicle. Spring Creek Pass generally offers more accessible parking options.
The best time to visit is typically from late June through September, after the snow has melted and before the first heavy snowfalls. However, always check local weather conditions, as high-altitude areas can experience rapid and unpredictable changes, even in summer.
Yes, dogs are generally allowed on the Colorado Trail, including Segment 21, which passes through the La Garita Wilderness. However, they must be kept on a leash to protect wildlife and ensure a pleasant experience for all trail users. Always practice Leave No Trace principles, including packing out all pet waste.
No, you do not need a specific permit to hike or jog Colorado Trail: Segment 21, nor is there an entrance fee. The trail passes through the La Garita Wilderness, which is managed by the US Forest Service, and generally does not require permits for day use or standard backpacking.
This segment is renowned for its stunning high-altitude scenery, featuring lush forests, wildflower-laden meadows, and spectacular panoramic views of distant peaks and striking red rock formations. You might also spot wildlife such as deer, elk, fox, marmots, and pikas.
Absolutely! Key features include the expansive Snow Mesa, a 3.3-mile stretch of open tundra offering dramatic views. The segment also connects San Luis Pass and Spring Creek Pass, both significant mountain passes.
Yes, this segment is part of the larger Colorado Trail and also overlaps significantly with the Continental Divide National Scenic Trail (CDT). You'll be sharing sections with these long-distance routes, including the CDT - Colorado Section.
Many areas along Segment 21 have abundant water sources. However, it's crucial to plan your water strategy, especially considering that the subsequent Segment 22 is known to start off very dry. Always carry enough water or a reliable filtration system.
The komoot tour for Colorado Trail: Segment 21 involves an elevation gain of approximately 1,992 meters (about 6,535 feet) and a similar amount of elevation loss.
