Mount Aix Trail

This is a very strenuous and hard hike. It involves a substantial elevation gain of 4,200 to 4,425 feet over a 12-mile round trip. The ascent is quick and steady with few breaks until Nelson Ridge. The upper sections feature loose, rocky terrain and can be narrow with steep, exposed slopes. It's recommended for experienced hikers with good stamina.

The trail starts on a dusty path through a moderately thick forest, with an easy stream crossing early on. It then becomes steep with switchbacks. Above the treeline, around 7,150 feet, the terrain changes dramatically to loose, rocky, and unstable slopes (talus/scree). Some sections, especially in the forest, can be eroded, and the ridge can be narrow with steep drops.

The trail begins at an elevation of approximately 3,700 feet. Parking is available at the trailhead. It's always a good idea to arrive early, especially on busy days, to secure a spot.

Yes, you will need a Northwest Forest Pass to park at the trailhead. Additionally, a self-issued wilderness permit is required for hiking within the William O. Douglas Wilderness. These permits are typically available at the trailhead.

Yes, dogs are allowed on the trail, but they must be kept on a leash at all times. Please remember to pack out all pet waste to help preserve the wilderness.

Due to its southwest exposure, the upper elevations of the trail tend to melt out earlier than other high-elevation trails. This makes it one of the first higher-elevation trails in the region to become accessible in the early season. However, always check current conditions with the U.S. Forest Service before planning your trip, especially after events like the Wildcat Fire.

From the exposed ridges and especially the summit, you'll be treated to expansive panoramic views of prominent Cascade Range peaks. These include Mount Adams, Mount St. Helens, the Goat Rocks, Mount Rainier, and the Stuart Range. The highlight View of Mount Rainier from Mount Aix offers a glimpse of what awaits.

There is an easy stream crossing early in the hike, which might be the only reliable water source, especially in late summer. It's crucial to carry enough water for the entire duration of this strenuous hike, as higher elevations may not have water.

There are two main options for the final push to the summit. One is a short, steep scramble gaining about 300 feet in roughly an eighth of a mile, which can involve hands-on sections and exposure. The other is a longer, official route (0.65 miles) that traverses a loose, rocky slope before climbing an exposed rocky rib. Both involve loose rock, but the longer route is generally considered less technical.

Yes, the Mount Aix Trail is part of a larger network. It connects to the Nelson Ridge Trail (#984) and the Richmond Mine Trail (#983). These can be combined to form a longer, approximately 17-mile loop that largely stays above 4,400 feet. Be aware that this loop is less frequently used and may require good route-finding skills.

As of recent reports (2024), the trail has experienced closures due to events like the Wildcat Fire. It is essential to check current conditions and any closure notices with the U.S. Forest Service before planning your trip to ensure safe and legal access.
