Aurora Ridge Trail

Aurora Ridge Trail is a 16.9-mile, one-way route from Sol Duc Road to the Happy Lake Ridge Trail junction. It climbs through old-growth forest onto a high, mostly forested ridge, then continues past the Eagle Lakes spur and Sourdough Mountain junction. Allow about 12 hours for the full traverse, and plan the continuation or return before you start; this is a serious backcountry route, not a casual day hike. Published mileage differs: current trail conditions give 16.9 miles to the junction, while another park page lists 15.1 miles without specifying the endpoint or whether it is one-way. This record follows the longer point-to-point route.

The first 2.5 miles climb steeply through old-growth forest. Once the route reaches the ridge, the grade eases and the tread becomes less consistently maintained. Small views open gradually, but expect a long stretch of trees and uneven ground rather than continuous panoramas. The change from a steep forest climb to a quieter ridge walk is the appeal; the early climb is the price of getting there.

Around mile five, a separate trail drops about half a mile to the small, tree-ringed Eagle Lakes. It is an optional spur, not part of the stored main route, and a good place to pause for birds. About three miles farther, the Sourdough Mountain junction leads to a short, steep climb to Sourdough Peak, roughly 300 feet above the ridge. From the 4,610-foot summit, the view can take in Lake Crescent, Ediz Hook, Mount Baker, Mount Olympus and Glacier Peak. The main route continues toward Happy Lake Ridge; neither spur is required to follow it.

The small trailhead is on the left along Sol Duc Hot Springs Road, roughly two to two-and-a-half miles from Highway 101; it holds about five vehicles and has no toilet. There is no food service at the trailhead or along the route, so carry what you need. Water is scarce after the first mile except at Eagle Lakes; treat any stream water before drinking. Some meadow sections are difficult to follow, so bring a map and compass and know how to use them. Snow can cover the high route in any season. Overnight trips require a wilderness permit and bear canisters; campfires are prohibited above 3,500 feet.

A shorter Aurora Ridge outing turns around at Sourdough Peak and returns the same way. That version is listed at about 16.8 miles round trip and is still a full-day hike; it is different from this record's one-way route to Happy Lake Ridge. The Eagle Lakes spur can also be visited from the same approach, but its distance is not part of the 16.9-mile main route.
