Uncompahgre Peak via Nellie Creek

This trail is generally rated as strenuous-difficult. It involves significant elevation gain over a moderate distance at high altitude, making it an endurance challenge. The final push to the summit includes a Class 2 scramble over loose rock, requiring the use of hands for balance. It's not highly technical but demands good physical conditioning and experience with high-altitude hiking.

There are two main starting points. The primary trailhead, known as the 4WD trailhead, is located at the end of the rough, narrow 4-mile Nellie Creek Road. A high-clearance 4WD vehicle is essential to reach this point. If you don't have such a vehicle, you'll need to start from the 2WD trailhead further down the road, which adds an extra 8 miles and 2,115 feet of elevation gain to your hike.

No, there are no specific permits or entrance fees required to hike Uncompahgre Peak via Nellie Creek. The trail is located within the Uncompahgre Wilderness, which is managed by the U.S. Forest Service. While no fees are required, always practice Leave No Trace principles to protect the fragile alpine environment.

Yes, dogs are generally allowed on this trail. However, it's crucial to keep them on a leash to protect wildlife and the delicate alpine ecosystem. Be mindful of the challenging terrain, high altitude, and potential for loose rock, which can be difficult for some dogs. Always pack out all pet waste.

The best time to hike is typically from late June through September, after the snow has melted and before new snow arrives. July and August offer the best chances for wildflowers. Always check the weather forecast before you go, as afternoon thunderstorms are common in the San Juan Mountains during summer, and conditions can change rapidly at high altitudes.

The trail offers continuous, spectacular views of the San Juan Mountain range, including Matterhorn and Wetterhorn Peaks. You'll pass through meadows, spruce-fir forests, and high-elevation alpine tundra with sparkling streams and ponds. The distinctive 'lopsided wedding cake' summit block of Uncompahgre Peak becomes increasingly visible. From the summit, you'll be rewarded with breathtaking 360-degree vistas. Keep an eye out for wildflowers and potential wildlife sightings like elk.

The trail starts with a gentle ascent through meadows and forest, then enters a rocky gully with switchbacks. It opens into picturesque meadows before transitioning to alpine tundra. Closer to the summit, you'll encounter steep switchbacks up a rocky hillside, a narrow traverse with some exposure, and a challenging 125-foot scramble over loose rock to reach the top. You'll also cross Nellie Creek, which is usually shallow enough to walk through.

Given the high altitude and challenging terrain, you should bring plenty of water, high-energy snacks, sturdy hiking boots with good ankle support, layers of clothing (including rain gear), sun protection (hat, sunglasses, sunscreen), a map and compass or GPS device, and a first-aid kit. Trekking poles can be very helpful for stability, especially on the descent and during the scramble sections.

The Uncompahgre Peak via Nellie Creek route is an out-and-back trail. You will return along the same path you ascended.

Yes, the route primarily follows sections of the Uncompahgre Peak Trail 239. It also briefly intersects with an Informal Connector and the Ridge Stock Driveway Trail 233.

Beyond general hiking safety, be prepared for rapidly changing weather, especially afternoon thunderstorms common in summer. Start early to be off the summit before noon. The high altitude can cause acute mountain sickness, so ascend slowly and hydrate well. The final scramble involves loose rock and exposure, requiring careful footing. Always inform someone of your plans and expected return time.
