Needleton Train Station

Highlight • Rest Area

The Durango and Silverton Narrow Gauge Railroad offers direct access to the Weminuche Wilderness via the Needleton Train Station. Trains run regularly during the summer season (noted on the Durango and Silverton Narrow Gauge Railroad website as being from May-October). If looking to hike into Chicago Basin, this is an option for cutting a good handful of miles off the hike by eliminating the need to hike in (and out) ten miles on the Purgatory and Animas River Trail.

Twin Lakes (Chicago Basin)

Highlight • Lake

The upper lakes in Chicago Basin vary in size depending on the time of year, and they serve as a great campsite or base camp for trying to bag some of the Chicago Basin 14ers. The lakes sit around 12,500 feet and are well above treeline and offer great views of the highest peaks in the area.

North Eolus

Highlight • Summit

North Eolus (14,042 feet) is a close neighbor to Mount Eolus and has a fairly similar summit route. Headed the opposite direction on the ridge, the North Eolus summit pitch is pretty easy class 3 scrambling. With route choice, this feels like one of the easier mountains in the Chicago Basin. Once on top of North Eolus, you have a head-on view of Sunlight and Windom Peaks to the west.

Mount Eolus

Highlight • Summit

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.

Frequently Asked Questions

Is the Mount Eolus & North Eolus trail suitable for jogging or trail running?

No, this trail is not suitable for jogging or trail running. Despite being categorized as 'jogging' in some systems, the route to Mount Eolus and North Eolus from Needleton is a highly challenging mountaineering endeavor. It involves significant hiking, scrambling, Class 2 and Class 3 climbing, and navigating exposed sections like the Catwalk. The terrain includes rocky slabs, boulder fields, and steep, technical ascents, requiring careful foot placement and route-finding rather than continuous running.

How do I access the trailhead for Mount Eolus & North Eolus from Needleton?

The most common access involves a unique journey. You'll need to take the Durango & Silverton Narrow Gauge Railroad to the Needleton Train Station stop. From Needleton, it's approximately a 6-mile hike into Chicago Basin, which serves as a popular base camp for ascending the peaks.

What is the best time of year to hike Mount Eolus & North Eolus?

The best time to hike these peaks is typically from late July through early September. During this period, snow has usually melted from the higher elevations, and weather conditions are generally more stable. However, always check current weather forecasts and snow conditions before planning your trip, as high-altitude weather can be unpredictable.

Are permits or fees required to hike in the Weminuche Wilderness?

No, there are no fees or permits required for hiking or camping within the Weminuche Wilderness itself. However, accessing the trailhead via the Durango & Silverton Narrow Gauge Railroad does incur a cost for the train ticket. Be aware that wilderness regulations regarding party size, camping, and campfires are in effect to preserve the pristine nature of the area.

What kind of terrain can I expect on the route to Mount Eolus and North Eolus?

The terrain is rugged and varied. The approach to Chicago Basin involves hiking through forests. Beyond the basin, you'll encounter rocky slabs, steep switchbacks, and boulder fields. The ascent to the summits includes Class 2 ramps, angled slabs, and sections requiring Class 3 scrambling, particularly on Mount Eolus. The Catwalk, a narrow and exposed ridge, is a notable feature between the two peaks.

Is the Mount Eolus & North Eolus trail dog-friendly?

While dogs are generally allowed in the Weminuche Wilderness, the highly technical and exposed nature of the route to Mount Eolus and North Eolus, including Class 3 scrambling and the narrow Catwalk, makes it unsuitable for most dogs. Consider leaving your canine companions at home for this particular summit attempt.

What are the main points of interest along the route?

Key points of interest include the scenic journey on the Durango & Silverton Narrow Gauge Railroad to Needleton, the beautiful Chicago Basin which serves as a base camp, and the stunning Twin Lakes. Of course, the ultimate highlights are the summits of Mount Eolus and North Eolus themselves, offering panoramic views of the San Juan Mountains.

Does the trail intersect with other well-known paths?

Yes, the route to Mount Eolus and North Eolus from Needleton utilizes sections of several official trails. You will primarily follow the Needle/Johnson Creek Trail and the Chicago Basin Trail for the approach to the basin. Higher up, the route becomes less defined, following the Mount Eolus Climber's Route and traversing The Catwalk.

What makes the Weminuche Wilderness experience unique for this trail?

The Weminuche Wilderness offers a true remote wilderness experience. Access via the historic Durango & Silverton Narrow Gauge Railroad immediately sets a unique tone. Once in the wilderness, you'll find pristine alpine environments, strict regulations to preserve its natural state, and the opportunity to experience high-altitude mountaineering away from developed areas. It's known for its spectacular scenery and the challenge of its 14,000-foot peaks.

What is the 'Catwalk' and how difficult is it?

The Catwalk is an iconic and memorable section of the ridge connecting Mount Eolus and North Eolus. It is a narrow, exposed ridge that, while mostly Class 2, includes sections requiring easy Class 3 moves. It has considerable exposure, meaning there are significant drop-offs on either side, requiring careful movement and a good head for heights.

Is there an easier way to reach the summits of Mount Eolus and North Eolus?

The approach from Needleton via Chicago Basin is the standard and most common route. There isn't a significantly 'easier' way to reach these summits, as both Mount Eolus and North Eolus are challenging Class 3 climbs. While North Eolus is generally considered slightly less technical than Mount Eolus, both require mountaineering experience and comfort with exposure and scrambling.
