High Divide Loop (Seven Lakes Basin)

Start at Sol Duc Falls Trailhead and follow the well-maintained path through old-growth forest to the falls, then turn onto Deer Lake Trail. This first stretch is shaded and forested, with a few creek crossings. Deer Lake sits in the woods about 2.9 miles beyond the falls; it is a natural place to pause before the sustained climb. The trail then heads south through subalpine vegetation toward the divide. Expect the grade to shift from moderate to steep, with views opening as you leave the trees.

At the high junction, take the short spur down into Seven Lakes Basin, then climb back to the divide to continue the loop. The spur is about half a mile each way and adds roughly a mile if you walk it both ways. It is the best place to look down over the basin's lakes, meadows, and dark conifer bands. Despite the name, eight or more lakes are scattered through the basin. If the clouds lift, frame the blue water below with Mount Olympus and the Bailey Range beyond it.

The High Divide is the exposed heart of the hike, with views toward Bogachiel Peak, the Hoh Valley, the Bailey Range, and Sol Duc Valley. The tread is well maintained overall, but the high route is not forgiving when snow-covered: steep snow slopes and ice can persist into early or mid-July, especially around Bogachiel Peak. The most reliable hiking window is mid-July through September. Wet, cool weather is possible even in season.

Continue east on High Divide to Heart Lake, then descend on Sol Duc River Trail to close the circuit at the falls access. The downhill leg is a long forest return, not a quick finish; keep time and energy for the walk back to the parking area. A few creek crossings are part of the route. Water comes from the river, streams, and lakes, but it must be treated. There is little water between Heart Lake and Deer Lake, so plan that stretch rather than assuming a source will be flowing.

Elk and bears are commonly seen in the Seven Lakes Basin area, and mountain goats are reported on the basin slopes; give wildlife room and keep food secured. Fishing is popular in many of the lakes, though Heart Lake and several of the smaller unnamed lakes have no fish. If you camp, sites are limited to designated areas and permits are limited year-round. A park-approved bear canister is required for food, garbage, and scented items. Vault toilets are available at Sol Duc Park, Heart Lake, Lunch Lake, and Deer Lake. Dogs are not allowed on this backcountry trail.
