The most common access point for Old Snowy Mountain is via the Snowgrass Flats Trailhead.

Other less common access points might exist, but Snowgrass Flats is generally considered the main starting point for summit attempts.
Yes, visitors to the Goat Rocks Wilderness, including Old Snowy Mountain, typically need a Northwest Forest Pass or an equivalent interagency pass for parking at trailheads. Additionally, a Wilderness Permit is required for both day use and overnight stays within the Goat Rocks Wilderness. These permits are usually self-issued at the trailhead registration boxes.
While the intro mentions summer and early fall as the best times, Old Snowy Mountain presents significant challenges in winter. The area receives heavy snowfall, making trails impassable without specialized gear like snowshoes or skis, and avalanche risk is high. Winter ascents are generally reserved for experienced mountaineers with proper training and equipment. Most hikers visit between July and October.
Reaching the summit of Old Snowy Mountain is a long and strenuous endeavor. While the round-trip distance is 14-17 miles, the significant elevation gain and varied terrain mean it typically takes 10-14 hours for a day hike. Many hikers opt for a multi-day backpacking trip, camping along the Pacific Crest Trail, to make the experience more enjoyable and allow for ample time to explore.
Yes, dogs are generally allowed in the Goat Rocks Wilderness, including the trails leading to Old Snowy Mountain. However, they must be kept on a leash at all times to protect wildlife and ensure a pleasant experience for all visitors. Please remember to pack out all pet waste.
The full summit hike to Old Snowy Mountain is considered challenging and not suitable for young children or beginner hikers due to its length, elevation gain, and rugged terrain. However, there are shorter, less strenuous trails in the broader Goat Rocks Wilderness area, such as sections of the Snowgrass Flats Trail that don't go all the way to the summit, which could be more suitable for families or those seeking a milder experience.
The Goat Rocks Wilderness is home to diverse wildlife. Hikers frequently report sightings of mountain goats, especially near the higher elevations and rocky outcrops. Other common sightings include marmots, pikas, and various bird species. Keep an eye out for deer and elk in the lower meadows, and occasionally, black bears or cougars, though these are rarer.
The main parking area for Old Snowy Mountain is at the Snowgrass Flats Trailhead. This lot can fill up quickly, especially on summer weekends and holidays, so arriving early in the morning is highly recommended. A Northwest Forest Pass or equivalent is required for parking. There are no public transport options directly to the trailhead, so personal vehicle access is essential.
Beyond the summit views, hikers will encounter several striking features. The McCall Glacier and Packwood Glacier are visible from the slopes. The trail also traverses sections of the Pacific Crest Trail (PCT), offering a glimpse into this iconic long-distance route. Near the summit, there's a distinctive natural rock arch, and the rugged, eroded remnants of the ancient stratovolcano are evident in the landscape.
