Colorado Trail: Segment 25 offers an incredible high-alpine experience, guiding you through vast meadows and rolling tundra with constant 360-degree views of jagged mountains and distant peaks like Engineer Mountain. This difficult 20.5-mile (33.0 km) hike, with 3287 feet (1002 metres) of elevation gain, is a long day out, typically requiring 11 hours and 48 minutes, but the visual rewards are immense.

For planning your visit, aim for July or August to experience the best conditions, as much of the trail is above 11,000 feet. The route is accessible from Molas Pass, and while some sections have gentle switchbacks, the overall elevation and length make it a demanding trek. Be prepared for a full day on the trail and carry adequate supplies.

This segment is renowned for its exceptional scenic beauty, often cited as one of the most visually rewarding sections of the entire Colorado Trail. You'll encounter clear, cold creeks and waterfalls, and the area around Molas Pass is particularly celebrated for its expansive vistas.

The Snowdon Peak from Andrews Lake route offers a diverse hiking experience, starting with a scenic walk around the popular Andrews Lake before ascending into the rugged Weminuche Wilderness. This difficult 6.1-mile (9.9 km) trail, gaining 2113 feet (644 metres) over an estimated 5 hours and 17 minutes, transitions from well-maintained paths through meadows and forests to a demanding summit push involving Class 3 scrambling on rock and tundra. You'll encounter stunning views of the San Juan Mountains, including Twin Sisters and Engineer Mountain, with the highlight being the dedicated viewpoint overlooking Snowdon Peak itself.

To make the most of your visit, plan to arrive early at the Andrews Lake trailhead, especially during peak season. Be aware that the higher altitude, starting at 10,750 feet, necessitates acclimatization for many hikers. While the initial section is family-friendly, the full ascent to Snowdon Peak is recommended only for experienced mountaineers due to challenging terrain and route finding. The wildflower season offers a particularly vibrant display in the meadows, but be prepared for potentially marshy conditions in some areas.

This trail is notable for its access to a "thirteener" (a peak over 13,000 feet) and its status as a gateway to the expansive Weminuche Wilderness. The initial section provides a great option for those seeking a shorter, scenic walk along the Million Dollar Highway, while the full summit offers a rewarding challenge for seasoned adventurers. Keep an eye out for diverse plant life, including beautiful columbine, and consider the northeast ridge route for a particularly fun and engaging ascent.

Lime Creek is the last decent and reliable water source if you hike the Colorado Trail southbound. There is a nicely shaded spot to take a break and filter the water. Campspots are not too easy to find here though.

Take a good look at Engineer Mountain, with its peak resembling a volcanic plug from a massive eruption 25–30 million years ago, sitting above a broad base. From the south, it looks like a balanced pyramid.

Celebration Lake is home to tons of axolotls! They are most active in the afternoon when the water is warmer. The lake is accessible by car, so you might have to share this spot with car campers. But no worries, there are plenty of options to pitch your tent.

The Colorado Trail is the only long-distance trail to let you stop a train in the middle of the wilderness. Take the short spur trail to Elk Park where you can flag down the train to take you into Silverton. The usual rate is 35 Dollars, but it is up to the conductor to charge less or even nothing.

Segment 25 of the Colorado Trail leads into the stunning, colorful San Juan Mountains and takes you along small lakes and to bubbling creeks and rushing rivers. The ascents and descents are not as steep as further north (east) along the trail.

Molas Pass sits a few yards below where the Colorado Trail passes the US 550 highway. Walk south 250 feet to the spur trail to the parking area and find Molas Overlook, a pit toilet, and parking at an elevation of 10,910 feet.
