Grand Pass - 11.9 Miles Round-Trip

Grand Pass is located 5.95 miles from Obstruction Point in Olympic National Park. It spans a divisive ridge between the Grand, Lillian River and Cameron Creek valleys with some of the best views in the park. The trail begins at 6,125' in open tundra before dropping into the valley just above Grand Lake. It continues by Moose Lake, Gladys Lake and a link of tarns, streams and snowfields up to the pass:

The Lillian Ridge Trail heads south from Obstruction Point and rolls moderately through open tundra with spectacular vistas and easy access to several perennial snowfields.

It crests at .7 miles (6,350') and drops steeply to a razor-thin ridge with rangy views down the Badger and Lillian River valleys (1.3 miles : 6,310').

The trail rises back up to a saddle (1.65 miles : 6,435'), where it shades east and drops precipitously down steep, barren slopes. Grand Lake soon comes in to view on the rapid descent.

The trail shifts quickly through pockets of krummholz as the forest gradually reconstitutes at lower elevations (2.65 miles : 5,400'). Open scree slopes give way to grassy meadows leading to a small creek (3.05 miles : 5,065'), where travel eases into a broad meadow at the Grand Pass - Grand Lake Trail split (3.5 miles : 4,945').

The Grand Pass Trail turns up valley to the wooded north edge of Moose Lake (3.85 miles : 5,045'), and emerges in a rolling meadow on its west shore where campsites are located (4.2 miles).

The trail continues above Moose Lake through the last of treeline to a spur for Gladys Lake (4.65 miles : 5,375'), located a few steps off the main trail. Gladys Lake is more aptly described as a pair of large, shapely ponds. It sees fewer day-hikers than the other two lakes, which may appeal to backpackers during peak season.

The trail clears treeline as the valley opens above Gladys Lake. Wildflowers are notably abundant along a network of braided, snow-fed streams in the upper valley.

The trail crosses a creek and makes a decisive turn (east) across the valley (5.1 miles : 5,555'), beginning a progressively - and at times prohibitively - steep push for the pass. Anticipate rugged conditions and several major snowfields on this section.

Travel moderates around a tarn (5.9 miles : 6,380') and up to Grand Pass (5.95 miles : 6,488'). The pass itself offers little room to maneuver, but a marked spur climbs 253' in just .25 miles up a razor-thin ridge to Grandview Peak (6,701') with panoramas that extend across much of the Park.

Worth Noting

  • Snow may linger and obscure portions of the trail well into summer, especially between Gladys Lake and Grand Pass. Technical skills and equipment may be required into early summer to reach the pass. Only experienced hikers / climbers should attempt the pass under such conditions.

  • The majority of the hike to Grand Pass is challenging and exposed in both directions. Plan around good weather with a very early start. Be mindful of changing weather and aim for safe terrain before storms develop.

  • Moose and Gladys lakes are especially attractive areas that warrant exploration if time permits. Grand Lake is visible for much of the descent into the valley, and requires additional effort to reach from the main trail. Day hikers may opt to skip Grand Lake in favor of more compelling destinations ahead.

  • Obstruction Point Road is subject to weather and damage closures without notice. Always call ahead for road conditions. The road sees heavy traffic when open, especially on weekends. The road is narrow with steep drop-offs in places. Weekday travel is preferable during peak season.

"Still some big snowfields above Gladys up to the pass, but very doable with a little effort. Traction of some kind is advisable though. The descent to Grand Valley is clear. The flowers are not quite there, but I imagine they'll be popping in 2-3 weeks."
