“Embark on the High Divide Loop, a scenic but strenuous odyssey through Olympic National Park's rugged beauty.”
The High Divide Loop, nestled in the heart of the Olympic National Park near Clallam County, Washington, is a challenging yet rewarding trek that spans approximately 35 kilometers (about 22 miles) with an elevation gain of roughly 1700 meters (approximately 5,577 feet). This loop trail is renowned for its stunning vistas, including the 7 Lakes Basin, and is rated as extra difficult due to its steep ascents and rugged terrain.
Getting to the Trailhead To reach the trailhead, hikers can drive to the Sol Duc Valley, which is accessible via Sol Duc Hot Springs Road off Highway 101. The nearest significant landmark is the Sol Duc Hot Springs Resort. For those relying on public transportation, options are limited, but during the summer season, there may be shuttle services available from nearby towns such as Port Angeles.
Navigating the Trail The journey begins at the Sol Duc Trailhead, where hikers will embark on a steady climb through old-growth forests. The ascent is gradual at first but becomes more challenging as you approach the junction with the Deer Lake Trail, about 4.2 kilometers (2.6 miles) in. Deer Lake, sitting at an elevation of 1,067 meters (3,500 feet), is a perfect spot to rest and enjoy the serene alpine environment.
Continuing on, the trail becomes steeper and more strenuous as you approach the High Divide. This section, approximately 11 kilometers (7 miles) from the trailhead, offers panoramic views of the Olympic Mountains and the chance to spot wildlife such as black bears and elk. Hikers should be well-prepared with navigation tools like HiiKER to ensure they stay on the correct path.
Landmarks and Wildlife As you traverse the High Divide, you'll reach the 7 Lakes Basin, a series of subalpine lakes that are a highlight of the loop. This area is approximately 14 kilometers (8.7 miles) from the trailhead and sits at an elevation of around 1,524 meters (5,000 feet). The basin is not only a visual spectacle but also a habitat for a diverse array of wildlife, including mountain goats and marmots.
Historical Significance The Olympic National Park, established in 1938, is a UNESCO World Heritage Site and an International Biosphere Reserve. The park's history is rich with Native American heritage, and the High Divide Loop traverses areas that were once hunting and fishing grounds for various tribes.
Preparation and Safety Given the trail's difficulty, hikers should be in good physical condition and have experience with backcountry navigation and camping if they plan to complete the loop over several days. Weather conditions can change rapidly, so it's essential to pack appropriate gear for cold and wet weather, even in the summer months.
Environmental Considerations As with any wilderness hike, it's crucial to practice Leave No Trace principles to preserve the beauty and ecological integrity of the area. Hikers should plan to pack out all trash and minimize their impact on the fragile alpine environment.
By preparing adequately and respecting the natural and historical significance of the High Divide Loop, hikers can enjoy a truly memorable experience in one of Washington's most breathtaking landscapes.
