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.

Upper Chicago Basin Trail

Highlight (Segment) • Trail

Chicago Basin Trail begins where the Needle/Johnson Creek Trail crosses over Needle Creek in the upper basin. It continues until the Windom Peak and Sunlight Peak summit routes part ways from each other. Many people travel to Chicago Basin to climb the high peaks in the area, but some people come just to get into the upper basin. There are alpine lakes and streams far above treeline right alongside the trail with camping above treeline available.

Windom Peak

Highlight • Summit

Even though it has been labeled by some as being the "easiest of all the Chicago Basin 14ers," Windom Peak is still a serious mountain peak with exposure, route finding, and class 2 scrambling. The mountain is also one of the first peaks to completely dry off in the summer and sees a few more visitors than the other peaks in the basin.

Frequently Asked Questions

How do I access the trailhead for the Chicago Basin via Needle Creek Trail?

The primary and most unique way to access this trail is by taking the historic Durango & Silverton Narrow Gauge Railroad. You'll disembark at the Needleton Train Station flagstop, which serves as the trailhead. The train ride itself offers spectacular canyon views along the Animas River Gorge.

What level of experience is needed for this hike?

This is classified as a difficult multi-day adventure, requiring a good level of hiking experience. While non-technical, it involves significant and relentless elevation gains, with sections gaining approximately 3,000 feet over short distances. The high altitude can also be a major factor for those not acclimated.

What kind of scenery can I expect along the route?

You'll experience breathtaking wilderness scenery, transitioning from dense forests along Needle Creek to dramatic alpine landscapes as you approach Chicago Basin. Expect pristine alpine lakes like Twin Lakes (Chicago Basin), vibrant wildflower meadows, towering jagged peaks, and numerous cascading waterfalls. Aspen groves also add to the beauty.

What is the best time of year to hike this trail?

The trail is most popular from July 4th through Labor Day, when wildflowers are abundant and the weather is generally favorable. However, this is also when the area can be most crowded. Visiting just outside this peak window might offer a more solitary experience while still enjoying good conditions.

Are there any permits or fees required to hike in Chicago Basin?

The trail lies within the Weminuche Wilderness, which is part of the San Juan National Forest. While there are typically no entrance fees for the wilderness area itself, specific regulations apply to preserve its character. Always check with the US Forest Service for the latest information on permits, especially for overnight stays, and any fire restrictions or bans, which are common due to the area's popularity and conservation efforts.

Is the Chicago Basin via Needle Creek Trail dog-friendly?

Yes, dogs are generally allowed on this trail as it's within the Weminuche Wilderness. However, they must be kept on a leash to protect wildlife and ensure a pleasant experience for all hikers. Always practice Leave No Trace principles, including packing out all pet waste.

What wildlife might I see on the trail?

Hikers frequently encounter abundant wildlife, most notably mountain goats, especially in the higher alpine areas. You might also spot various bird species and other high-altitude mammals. Remember to observe wildlife from a distance and never feed them.

Does the trail connect with other routes?

Yes, the route primarily follows the Needle/Johnson Creek Trail and the Chicago Basin Trail. Once in Chicago Basin, it provides access to other routes like the Upper Chicago Basin Trail and climber's routes for the surrounding fourteeners, such as the Windom Peak Climber's Route and Sunlight Peak Climber's Route.

Can I summit fourteeners from Chicago Basin?

Absolutely! Chicago Basin is a renowned base camp for mountaineers aiming to summit four of Colorado's 'fourteeners' (peaks over 14,000 feet): Windom Peak, Sunlight Peak, Eolus, and North Eolus. While Windom Peak is considered more manageable, others like Eolus and Sunlight Peak require more technical climbing and scrambling.

What should I know about backpacking in Chicago Basin?

As a multi-day backpacking trip, be prepared for self-sufficiency. The area is remote with limited connectivity. Due to its popularity, especially during peak season, strict regulations are in place, including a campfire ban, to preserve its wilderness character. Always pack out everything you pack in, and be prepared for rapidly changing alpine weather conditions.

Is the trail accessible in winter?

Winter access to Chicago Basin is extremely challenging and generally not recommended for casual hikers. The Durango & Silverton Narrow Gauge Railroad typically does not operate to Needleton in winter, making access much more difficult and requiring advanced backcountry skills, avalanche awareness, and specialized gear.
