The Sphinx Mountain Trail is rated as difficult due to its significant elevation gain, which can range from 4,470 to 5,000 feet, and its strenuous terrain. Beyond the initial maintained section, hikers encounter a steep gully, loose scree, and rocky trails, especially in the upper sections. The total round-trip distance is typically 12 to 14 miles, taking 5 to 8 hours to complete.
The first five miles of the trail are generally well-maintained, leading to a saddle between the Helmet and Sphinx Mountain. After this point, the terrain becomes much more demanding, featuring a steep gully, loose scree, and rocky scree trails. Closer to the summit, you'll navigate open, semi-steep slopes and distinctive conglomerate steps and slabs. Early in the season, snow may still be present in the main drainage.
From the summit of Sphinx Mountain, you'll be rewarded with breathtaking panoramic views. These include expansive vistas of the Madison Valley, the Spanish Peaks, Buck Ridge, and Cedar Mountain, stretching across mountains, canyons, and valleys in every direction. The mountain itself, with its unique 'blob-like' shape and reddish-brown conglomerate rock, is also a striking feature.
Wildlife sightings are common on this route, with bears and goats frequently observed. It is highly recommended to carry bear spray and know how to use it. Always maintain a safe distance from all wildlife.
The Sphinx Mountain Trail typically starts from a designated trailhead in the Madison Range. While specific parking details can vary, it's generally advisable to arrive early, especially during peak season, to secure a spot. Always check local regulations for trailhead access and parking availability before your visit.
The best time to hike the Sphinx Mountain Trail is generally from late spring through early fall. However, be aware that snow can persist in the main drainage to the summit during the early season. Always check current trail conditions and weather forecasts before planning your trip.
Yes, dogs are generally allowed on the Sphinx Mountain Trail. However, as the trail is located within the Lee Metcalf Wilderness, specific regulations apply. Dogs must be kept under control at all times, and it's best practice to keep them on a leash to protect wildlife and ensure a pleasant experience for all hikers. Please pack out all waste.
The Sphinx Mountain Trail is located within the Lee Metcalf Wilderness. Generally, there are no entrance fees or permits required for day hiking in this wilderness area. However, all visitors are expected to adhere to Leave No Trace principles and wilderness regulations to preserve the natural environment.
Yes, the route primarily follows the Sphinx Mountain Trail for a significant portion. It also intersects with sections of the Bear Creek Trail and Bear Creek.
No, the Sphinx Mountain Trail is rated as difficult and is not recommended for beginners or families with young children. Its strenuous nature, significant elevation gain, and challenging terrain, including steep gully sections and loose scree, require a high level of fitness and experience. There are many other family-friendly options in the broader Madison Range area for those seeking less demanding hikes.
Given the trail's difficulty and remote nature, essential gear includes plenty of water, high-energy snacks, sturdy hiking boots, layers of clothing for changing weather, navigation tools (map, compass, or GPS), and a first-aid kit. Due to the presence of wildlife, carrying bear spray is highly recommended. Trekking poles can also be very helpful for navigating the steep and loose terrain.
