At 12,968 feet, Engineer Mountain doesn't quite qualify as a Colorado 13er. That being said, it is one of the most unique and fun mountains in the San Juans. The ridge up to the summit involves some class 2 and class 3 moves, but the route is clear and easy to follow. This is a great route to introduce someone to class 3 travel, and you are not lacking any views once you reach the summit.

At 12,285 feet, Deadwood Mountain is one of the most accessible peaks in the La Plata Mountains. Like most of the summits in the range, Deadwood Mountain is approached via an old, rocky mining road. Once you break treeline, the trail tuckers out, and you follow the ridge (with some evidence of a trail/path) to the top.

Diorite Peak (12,761 feet) is one of the most central mountains in the La Platas. The mountain is usually approached via a rocky logging road that ends in the midst of a bunch of switchbacks climbing up the southern face of the mountain. The trail is mainly class 1, but it is super steep in sections. You can truly see the entire La Plata Mountain Range from the top of this mountain.

Mount Eolus (14,087 feet) is a class 3 14er in the Chicago Basin group. The scramble to the summit is straightforward, but there is some real exposure on the traverse. The "Catwalk" is the name for the most narrow section on this ridge. Mostly all of the traverse is long stretches of class 2 (including this tight section). There are a handful of class 3 sections as you approach the very top.

The prime season for hiking most of the higher mountain peaks in the San Juan National Forest is typically late July through early September, when snowmelt is largely complete and weather is generally more stable. This period also offers the best chance to witness vibrant alpine wildflowers, especially in areas like the American Basin.

Find more details on these activities in the MTB Trails, Gravel Biking, and Road Cycling Routes guides for the region.
