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.

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.

This uphill section of the Engineer Mountain Trail is not very technical, but due to the elevation and the steepness of the trail you'll breath heavily. But the good thing is: You'll pedal slowly and have plenty of time to enjoy the beautiful scenery.

Little Molas Lake is a high-altitude body of water at about 11,000 feet. It is located nearby parking lots and provides easy access to the Colorado Trail. It is the ideal place to enjoy a packed lunch before or after your ride.

It is a popular trail with great panoramic views. It is located just east of Engineer Mountain, which is easily recognisable by its two cone-like peaks. The climbs are challenging and bring you to beautiful alpine meadows at the base of the peaks.

Deer Creek is a mostly peaceful, flowy and fun trail. However, once you get to this last section (in the downhill direction), you will find that the difficulty drastically changes. The descent suddenly includes very tight corners on steep terrain. It is great fun if you are able to tackle the technical challenges, but is also something to keep in mind for less daring bikers, as this is an unavoidable section of the trail.

This is a fun and long trail which extends north and south beyond this section between its intersections with Coal Creek and Engine Creek Trails. The northern part is more technical, while the southern one is considered to be the more fun one. The views are beautiful and the trail is easily accessed via multiple entry points.
