The Colorado Trail: Segment 25 typically starts near Molas Pass. You can find parking at the Molas Pass Trailhead, which is a common access point for this segment. Another key access point is the Little Molas Lake Trailhead.
No, there are generally no permits or entrance fees required to hike Colorado Trail: Segment 25. It is located within the San Juan National Forest, which typically does not charge for day-use access to trails. However, always check the latest regulations from the US Forest Service before your trip, especially if you plan to camp overnight.
Yes, this segment of the Colorado Trail is generally dog-friendly. However, it's crucial to keep your dog on a leash to protect wildlife and ensure a pleasant experience for all hikers. Always pack out all waste and ensure your dog is prepared for high-altitude hiking conditions.
The best time to hike Colorado Trail: Segment 25 is typically during July and August. During these months, the high-alpine tundra is vibrant with wildflowers, and the weather is generally more stable. Hiking outside of this window, especially in late spring or fall, can mean encountering snow and more unpredictable conditions.
While some sources rate it as easy to intermediate for day hikes, the full segment is considered difficult due to its length (approximately 20.5 miles or 33 km) and high elevation. Much of the trail lies above 11,000 feet, topping out around 12,500 feet. The grade is often reasonable, but the sustained effort at high altitude requires significant energy.
The terrain is a mix of single-track trail and old, reclaimed roads. You'll encounter both forested areas, including old-growth Engelmann spruce, and lush, grassy meadows. A significant portion of the trail is high alpine and goes above the treeline, offering extensive views. In 2022, a former jeep road section was converted into a trail exclusively for hikers and bikers.
This segment is renowned for its panoramic 360-degree views of the Rocky Mountains, including impressive peaks like Engineer Mountain. You'll pass by beautiful alpine lakes such as Little Molas Lake and Celebration Lake. Expect to see meadows abundant with wildflowers, clear, cold creeks, and even a waterfall.
Yes, you'll find numerous clear, cold creeks along the trail that can serve as water sources, though filtering is always recommended. There are also several informal campsites, including a campsite with a fire ring, particularly in the forested sections. Some milky streams are also noted, which might require extra filtration.
Given the high-alpine meadows and forested areas, you might spot deer, especially in the open meadows. Keep an eye out for various bird species and smaller mammals common to the Rocky Mountains. Always maintain a respectful distance and do not feed wildlife.
Yes, while primarily following the Colorado Trail, this route also passes through sections of the Twin Sisters / Colorado Trail and the Rico-Silverton Trail. The main path is, of course, the Colorado Trail (Segment 25) itself.
Due to its length, high elevation, and overall difficulty rating, the full Colorado Trail: Segment 25 is generally not recommended for beginners or families with young children. However, shorter out-and-back sections from trailheads like Little Molas Lake Trailhead could be suitable for more experienced families looking for a day hike at altitude.
