Hiking West Maroon Pass: Trail Map, Weather, Gear, Camping

The West Maroon Pass Trail is a classic high‐alpine route between Aspen and Crested Butte. It climbs from the Maroon Lake trailhead (≈9,580 ft) over a 12,500 ft pass and down into the CB area. Hikers can expect ~10.5–11 miles one-way (≈21–22 mi round-trip) with roughly +3,000 ft elevation gain from Aspen (and ~2,350 ft gain from CB). It’s rated strenuous (steep rocky trails and river crossings). Most parties take 6–10+ hours one-way. The trail traverses Maroon Bells–Snowmass Wilderness, so careful planning (shuttles, permits, weather) is essential.

How long and difficult is the West Maroon Pass hike?

 

One-way it’s about 10.5–11 miles (≈17 km) between Maroon Lake (Aspen side) and Schofield Park (CB side). Starting at 9,580 ft it climbs roughly +3,000 ft to 12,500 ft at the pass (Aspen→CB), then descends ~2,300 ft. From CB to Aspen the ascent is ~+2,357 ft. The trail is classified strenuous, with steep pitches (especially the final mile) and two major creek crossings (on the Aspen side). Most hikers need 6–10 hours one-way, so allow a full day each way (a back-and-forth would be 12–16+ hours).

 

 

When is the best time to hike, and what weather should I expect?

 

The trail is snow-free and safe roughly late June/early July through mid-October. Peak wildflowers bloom in mid-July–August, and fall aspens glow in late September. Morning starts are critical: afternoon thunderstorms are common at high elevation. Plan to summit by late morning and descend by early afternoon. Spring (snowmelt) can leave deep snowfields and high, fast creeks. Always check current snow and weather reports before heading out.

 

What gear is needed for day hikes vs. overnight trips?

 

For a day hike pack: sturdy boots, rain jacket and warm layers (temps can drop quickly), sun protection, at least 3–4 L of water, snacks, map/GPS, and a first-aid kit. Trekking poles and waterproof shoes are highly recommended for the creek crossings. For an overnight backpack: add a lightweight tent, warm sleeping bag, camp stove (fires prohibited above tree line), and a bear‐proof food container (required in this wilderness). Early-season hikers should carry micro spikes or crampons in case of snow patches, and always pack out all trash and waste.

 

 

Do I need permits or passes?

 

Yes. The Aspen trailhead is in the Maroon Bells–Snowmass Wilderness and Maroon Bells Scenic Area. Parking/shuttle reservations ($10/vehicle) are required at Maroon Lake from mid-May to Oct 31. A Pitkin County bus or parking permit is needed to access Maroon Lake (cars are barred 8 am–5 pm). For backcountry camping, overnight permits are required year-round in the Maroon Bells Wilderness. Some zones (e.g. Crater Lake, Capitol Lake) have reserved campsites; elsewhere you may use any established site at least 70 big steps from water/trails.

 

 

What shuttle and transport options exist?

 

Since this is a one-way hike, plan transportation carefully. Pitkin County’s Maroon Bells Shuttle runs 8 am–3 pm from Aspen Highlands to Maroon Lake for \$16 one-way. Alternatively, friends can drop you off at Maroon Lake between 6–8 am (no vehicle permit needed then); after 8 am they must buy a one-way ($16) shuttle ticket to return. From Crested Butte, private van shuttles (Dolly’s Mountain Shuttle or Alpine Express) will drive you to the West Maroon trailhead (Schofield Park). Expect ≈\$55 per person or a \$220 minimum fare. Both services also offer pick-ups at Schofield Park at day’s end. Reservations are advised well in advance.

 

 

Where can I camp along the trail, and what rules apply?

 

There are no developed campgrounds on the trail, but primitive backcountry sites exist. On the Aspen side, designated tent sites are at Crater Lake (permit zone); otherwise, you can camp near West Maroon Creek once past Crater Lake (keep 100 ft from water/trails). On the Crested Butte side, campsites dot the woods around the West Maroon trailhead and along the East Fork valley (near Frigid Air cabin). If the trailhead sites fill, you can drive a few miles up the old road to the Paradise Divide area for dispersed sites (4WD required). Remember Leave-No-Trace: pack out waste, bury human waste 6–8″ deep at least 100 ft from water/trail, and use a camp stove (no campfires above tree line). Certified bear canisters are mandatory for overnight trips.

 

 

What are the top scenic highlights and photo spots?

 

There are many. At the trail’s start, Maroon Lake (9,580 ft) offers the quintessential view of North and South Maroon (the Bells) reflected in the water. At 3.5 mi the Crater Lake basin sits at the Bells’ base (10,141 ft) – a gorgeous alpine lake at the foot of the peaks. Above treeline, the wide West Maroon valley blooms with wildflowers (especially mid-July–Aug). The panorama from West Maroon Pass itself (12,500 ft) looks down into the Purity Basin and the rugged Elk Range. On descent, the view unfolds into a broad U-shaped valley (“like the Swiss Alps”) leading toward Crested Butte, with Pyramid Peak and others filling the skyline.

 

 

What attractions are near the Aspen (west) trailhead?

 

The Aspen trailhead is at Maroon Lake in the Maroon Bells area. It’s famous for the Maroon Bells (two 14ers), one of Colorado’s most photographed scenes. The Crater Lake trail (3.5 mi round-trip) leads to the base of the Bells. Other nearby hikes include the Conundrum Hot Springs/Buckskin Pass trail and any segment of the Four Pass Loop. Note: parking beyond 8 am requires a $10 reservation or shuttle.

 

 

What attractions are near the Crested Butte (east) trailhead?

 

The trail emerges on Gothic Road, 14 mi north of Crested Butte town. Along this road you pass Emerald Lake and the ghost town of Gothic before reaching Schofield Park. The town of Crested Butte (≈11 mi further) is a lively mountain town with shops, dining and a ski resort. Nearby is scenic Kebler Pass (famous for aspens in fall) and Slate River/Lost Lake near Crested Butte. The Schofield trailhead itself has parking and vault toilets, but camping there is primitive.

 

 

What general tips apply to alpine hikes like West Maroon Pass?

 

High‐altitude passes demand respect. Start very early, carry multiple warm/dry layers, and monitor weather closely – Colorado mountains are notorious for afternoon storms. Bring navigation tools (maps/GPS) and stay hydrating. Trekking poles help balance, especially at stream crossings. If snowfields or heavy runoff remain (often into July), know how to ford creeks safely or consider turning back. Always inform someone of your plan and pack a flashlight (finish before dark). In short, treat it like a true alpine adventure: early start, light pack, and cautious planning.

 

 

What are some easier alpine pass hikes in Colorado?

 

One example is the Monarch Pass Loop (Salida): about 3.2 mi with ~488 ft gain, rated easy. (Most “passes” are higher and steeper, but the Monarch trail is a good easy alpine-altitude trek.)

Which part of West Maroon Pass is hardest?

 

The two creek crossings on the Aspen side and the final climb’s steep switchbacks are the most challenging sections.

Do I need a permit to hike West Maroon Pass?

 

Overnight: Yes – camping in the Maroon Bells–Snowmass Wilderness requires a backcountry permit. Day-use: Vehicles/people need the Aspen Maroon Lake reservation/fee ($10) or shuttle pass during summer.

 

 

What is the difference between West and East Maroon Pass?

 

West Maroon is shorter (~12 mi one-way) but steeper, with higher trail traffic. East Maroon is longer (~15 mi), has fewer hikers and gentler grades. Both traverse the Elk Range but via different valleys.

Are dogs allowed on the trail?

 

Yes – dogs are permitted but must be kept on leash at all times. They should be fit for long alpine hikes, and owners must pack out all pet waste.

Which shuttle services run Aspen–Crested Butte?

 

The Pitkin County Maroon Bells Shuttle runs Aspen Maroon Lake ($16 one-way). Private shuttles (Dolly’s Mountain Shuttle, Alpine Express) meet hikers at Schofield Park and connect to Aspen or Crested Butte. Expect ≈\$55 per person one-way. Always book these shuttles well in advance.
