“Trek the Enchanted Valley-LaCrosse Basin Loop, an epic 83 km journey through Olympic National Park's diverse wilderness.”
Embarking on the Enchanted Valley - LaCrosse Basin Loop is a journey through the heart of Olympic National Park's rugged wilderness. This approximately 83 km (52 miles) trek with an elevation gain of around 3100 meters (10,170 feet) is a challenging adventure that will take you through diverse landscapes, from lush rainforests to alpine meadows.
Getting to the Trailhead
The trailhead is accessible near Jefferson County, Washington. If you're driving, you can reach it by taking US Highway 101 to the Graves Creek turnoff, which is located just past the Quinault Rain Forest Ranger Station. Follow the road to its end, where you'll find the parking area for the trailhead. For those relying on public transportation, options are limited, but during the summer months, there may be shuttle services available from nearby towns to the Quinault area.
The Journey Begins
As you set out from the trailhead, you'll initially follow the East Fork Quinault River through old-growth temperate rainforest, home to towering Douglas firs and western hemlocks. The first 21 km (13 miles) to Enchanted Valley is relatively moderate, with an elevation gain of about 600 meters (1,968 feet). This valley, often referred to as the "Valley of 10,000 Waterfalls," is especially stunning in the spring when snowmelt feeds the numerous cascades.
Historical Significance
The Enchanted Valley also holds historical significance, as it is the site of the Enchanted Valley Chalet, a backcountry lodge built in the 1930s. While the chalet no longer operates as a lodge, it stands as a testament to the early recreational use of the park.
Ascending to LaCrosse Basin
Beyond Enchanted Valley, the trail becomes more strenuous. You'll ascend steeply to Anderson Pass, which is about 10 km (6 miles) from the valley, gaining roughly 900 meters (2,953 feet) in elevation. From Anderson Pass, you have the option to take a side trip to the Anderson Glacier, which adds about 3 km (2 miles) to your journey.
Continuing on the loop, you'll traverse the high alpine terrain of LaCrosse Basin, a stark contrast to the lush valley below. This area is dotted with pristine lakes and offers a chance to spot mountain goats and black bears, so be sure to practice safe wildlife viewing and food storage.
Navigating the Loop
For navigation throughout the hike, HiiKER is an excellent tool to keep you on track. The app provides detailed maps and trail information that can be invaluable in the remote sections of the park where the path may be less defined.
Descending Back to the Trailhead
The final leg of the loop will take you down through the Dosewallips River drainage, with a steady descent back towards the Quinault River. This section is approximately 32 km (20 miles) and completes the loop back to the trailhead.
Preparation and Safety
Given the trail's difficulty, it's essential to be well-prepared with the appropriate gear, including a map, compass, and GPS device. Weather can change rapidly in the mountains, so pack for all conditions. It's also crucial to have a bear canister for food storage, as bears are active in the area.
Permits are required for overnight stays in Olympic National Park, and it's wise to check in with the ranger station for the latest trail conditions and bear activity. Always leave a detailed trip plan with someone before heading out, and be prepared for a challenging but rewarding experience in one of the Pacific Northwest's most beautiful landscapes.

The usual start for the Enchanted Valley - LaCrosse Basin Loop is the Graves Creek Trailhead in the Quinault area of Olympic National Park. There is a parking area at the end of Graves Creek Road, but access can change when road damage or bridge work affects the corridor, so current road status matters for whether the trailhead is reachable.

The East Fork Quinault River corridor and Enchanted Valley are managed with overnight quotas, so permits can be limited during the main hiking season.
No. The Enchanted Valley - LaCrosse Basin Loop is inside Olympic National Park, where dogs and other pets are not permitted on most park trails, and there is no backpacking route within the park where dogs are allowed. That makes this loop unsuitable for anyone planning to hike with a dog.
