One of the most unusual ways to start a backpacking trip in Colorado is to board a coal-fired steam train. The Durango and Silverton Narrow Gauge Railroad has carried hikers into the Weminuche Wilderness for generations, dropping them at remote flag stops with no road access. If your goal is Chicago Basin and the Needle Mountains, the train turns a brutal multi-day approach into a scenic ride along the Animas River. Here is how to use it.
Why Take the Train
The Weminuche is the largest wilderness area in Colorado, and its core peaks sit far from any road. Without the railroad, reaching Chicago Basin means a long approach from the Purgatory or Vallecito trailheads. The train cuts that down dramatically by dropping you near the trail. For the full trip plan that builds around this access, see our Weminuche Wilderness Chicago Basin backpacking itinerary.
The Two Key Flag Stops
- Needleton is the classic drop for Chicago Basin and the three 14ers, Eolus, Sunlight, and Windom. From the footbridge over the Animas River, the Needle Creek Trail climbs roughly 6.5 miles to the basin.
- Elk Park sits a few miles upstream and connects to the Elk Creek Trail and the Colorado Trail, opening up loops toward the Grenadier Range and points north.
How the Drop-Off Works
You buy a wilderness access ticket rather than a standard sightseeing fare. When you book, you choose your drop-off stop and a return pickup date and stop. The train slows at the flag stop, the crew helps unload packs, and then it pulls away, leaving you in the quiet of the canyon. On your return day you wait at the stop with your pack visible so the engineer knows to halt. Always confirm the current schedule and seat availability directly with the railroad before your trip, since departures change by season.
Timing and Schedules
The full Durango to Silverton steam service generally runs from late spring through fall, with the most reliable wilderness drop-offs in summer. Early and late season may use shorter routes or different equipment, so check before counting on a specific stop. Give yourself buffer days. Mountain weather can pin you in the basin, and you do not want a tight return that forces you to summit in a storm. Most parties plan three to five days for a Chicago Basin trip.
What to Pack for Train Access
Because you cannot resupply once you step off, your pack must hold everything for the trip. Carry all food, fuel, and layers for your planned days plus a contingency day. Bring solid bear and critter protection, but note that the bigger nuisance here is mountain goats that crave salt and will chew sweaty gear. A reliable water filter is essential since you will draw from Needle Creek and alpine tarns. Pack a printed copy of your ticket and pickup details, as cell service is nonexistent in the canyon.
Alternatives if the Train Is Full
Steam departures sell out in peak summer, especially on weekends. If you cannot get a seat, you can hike in from the Purgatory Trailhead off Highway 550, which adds significant distance and a descent to the Animas before the climb to Chicago Basin. The Vallecito approach is another option for those seeking a longer, quieter trip. Either way, the train remains the most efficient and memorable entry into the high Weminuche.
Bringing It Together
The narrow gauge railroad is more than transportation, it is part of the experience. Riding through the Animas River canyon to reach trail-only wilderness is a rare way to begin a backpacking trip in the lower 48. Book early, build in weather days, and treat the drop-off as the start of a self-sufficient adventure in one of Colorado's wildest corners.
