How 4 days in Weminuche split up
The Weminuche Wilderness is Colorado's largest designated wilderness area, 499,771 acres of the San Juan Mountains with no roads, no cell service, and some of the most dramatic high-alpine terrain in the lower 48. At its heart is Chicago Basin, a remote cirque ringed by three 14,000-foot peaks and accessible by one of the most memorable approaches in American backpacking: a steam-powered narrow gauge railroad that drops you off trackside, miles from the nearest road.

Train to Needleton, hike to Chicago Basin
Board the Durango & Silverton Narrow Gauge Railroad at Durango Depot, departing around 8:45am. The three-hour ride through the Animas River Gorge is spectacular, with sheer canyon walls, rushing water, and no road access the entire route. Tell the conductor at boarding that you're stopping at Needleton. The train slows to let backpackers off at the whistle stop, then continues to Silverton.
Not the order you want? Drag a stop, or use the arrows beside it. Stops move between days too.
Base in~3.5 hr from Albuquerque · base town · DriveDurango is the base town for this trip. It is about 3.5 hours from Albuquerque, 5.5 hours from Denver, and 6 hours from Salt Lake City. Spend the night before so you can catch the morning train, and download offline maps before you lose cell service in the wilderness.

Needle Creek Trail to Chicago Basin7 mi · 3,200 ft gain · 4 to 5 hr · HikeFrom Needleton (8,212 ft), cross the bridge over the Animas River and climb the Needle Creek Trail. The first two miles gain gradually through spruce-fir forest before the valley opens and the Needle Mountains come into view. The trail climbs steadily for 7 miles total, gaining 3,200 feet to the basin. Plan 4 to 5 hours hiking time.
Camp in Chicago BasinEstablished sites · Needle Creek · 11,400 ft · CampSet up camp at an established site along Needle Creek in the upper basin at 11,400 ft. The most popular sites are in the flat, grassy areas between the lower and upper basin. A bear canister is required and enforced. Filter all water from the creek, and spend the evening watching the sun set on Eolus, Windom, and Sunlight above.

Summit Windom Peak (14,087 ft)
Start before 7am. Windom Peak is the most straightforward of the three Chicago Basin 14ers, a Class 2 route with no technical moves, though the altitude and long approach require genuine fitness.

- Windom Peak (14,087 ft)
Class 2 · be off the ridge by noon · HikeStart before 7am. Windom Peak is the most straightforward of the three Chicago Basin 14ers, a Class 2 route with no technical moves, though the altitude and long approach require genuine fitness. From camp, follow the trail past the upper basin toward the Twin Lakes, then veer southeast up the broad talus toward the Windom-Sunlight saddle and the rocky upper ridge.
Twin Lakes & Windom-Sunlight saddleUpper basin talus approach · ViewpointThe route past the upper basin runs by the Twin Lakes, then climbs the broad talus slopes toward the Windom-Sunlight saddle. The upper ridge to Windom is a straightforward rocky walk with increasingly dramatic views of the Needle Mountains and the San Juan backcountry.
SFC H / CC BY 3.0Second night in Chicago BasinSame base · rest and refuel · CampReturn to camp by early afternoon. Rest, filter water, and eat a real meal. Your legs will thank you the next day. Keeping the same base means no packing up between summit days, and the basin night sky at 11,400 ft with no artificial light is extraordinary.

Sunlight Peak or basin exploration
Option A, Sunlight Peak (14,059 ft, Class 3): Sunlight is the technical challenge of the three. The standard route follows the same approach as Windom to the Windom-Sunlight saddle, then traverses northwest along the ridge to the summit block. The final move to the true summit involves a Class 3 step across an exposed notch, manageable for experienced scramblers, not recommended for those uncomfortable with exposure. Do not attempt in wet or stormy conditions.

Twin Lakes & upper basin · Option B~12,500 ft · half-day · no summit push · ViewpointThe Twin Lakes above camp at around 12,500 ft are a rewarding half-day objective that doesn't require a summit push: crystal-clear high-alpine lakes surrounded by talus, wildflowers in July, and views back down the basin to the valley below. This is the right call if weather is uncertain or your legs are still recovering.
Last night in Chicago BasinSit with the silence · CampReturn to camp by early afternoon. This is your last full night in the basin, so take an hour to sit with the silence. At 11,400 feet with no artificial light, the night sky here is extraordinary.

Hike out to Needleton, train to Durango
The return train from Needleton to Durango typically departs between 3:30 and 4pm, so confirm the exact schedule when you buy tickets, as it varies by date.

What we actually learned in the basin.
Book the train months ahead
The Durango & Silverton Narrow Gauge Railroad runs round trip for about $110 to $130 and sells out months in advance for summer weekends. Backpacker tickets are the same price as regular tourist tickets. Tell the conductor when you board that you're getting off at Needleton, and confirm the once-daily return schedule when you book.
A bear canister is mandatory
No wilderness permit is required for the Weminuche Wilderness, but a bear canister is required and actively enforced by rangers. Campsites are first-come, first-served, and established sites in Chicago Basin fill fast on July and August weekends. No campfires above 11,000 ft.
Filter everything from Needle Creek
Water from Needle Creek and the snowmelt streams throughout the basin is plentiful, so filter everything. Camp at established sites in the flat, grassy areas between the lower and upper basin to keep the heavily used basin pristine.
Expect zero cell service
Cell service is nonexistent across the wilderness. Download offline maps, screenshot the trail and the train schedule, and tell someone your plan before you board. There are no facilities at the Needleton whistle stop.
Be off the summits by noon
Afternoon thunderstorms develop rapidly in the San Juans, and the exposed 14er ridgelines are dangerous in lightning. Start summit days before 7am and be off the ridge by noon. Do not attempt Sunlight's exposed Class 3 move in wet or stormy conditions.
Go mid-July through September
July brings wildflowers and the most dramatic snowmelt streams, but snow can still cover upper routes early in the month. August is peak season with the best conditions and the most crowds. September offers solitude, stable weather, and golden aspen. Upper basin trails are often snow-covered before mid-July.
Pack thermal layers and a rain hardshell
The San Juan routes above the basin are exceptionally steep and top out over 12,000 feet, where afternoon monsoon storms roll in hard and cold with intense lightning. Pack high-quality thermal layers and a proper rain hardshell, not just a wind shell, and plan your daily miles so you are back in camp below timberline by about 1pm, before the storms build.
Everything you'll actually want to know.
