Grand Lake - 7.6 Miles Round-Trip

Grand Lake (4,755') is located 3.8 miles from Obstruction Point in Olympic National Park. This popular lake sits just below treeline at the foot of Grand Valley, one of Olympic's most scenic and celebrated alpine destinations. While the lake is exceptional, the hike itself is equally compelling.

The trail begins at 6,125' and traverses open tundra for 1.65 miles before dropping into the valley. Views extend to Mt Olympus and across several distinct ranges and valleys.

Marmot, grouse, deer and mountain goat are common, and wildflowers rival any in the Park. The Grand Pass Trail continues up valley to Moose Lake, Gladys Lake and Grand Pass:

The Lillian Ridge Trail heads south from Obstruction Point across open tundra with panoramic views and easy access to perennial snow fields.

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 to a saddle (1.65 miles : 6,435'), where it shades east and drops sharply down steep, barren slopes. Grand Lake soon comes in to view on this very fast descent.

The trail shifts quickly through patches of krummholz as the forest reconstitutes at lower elevations (2.65 miles : 5,400').

Open rocky slopes give way to grassy meadows leading to a small creek (3.1 miles : 5,065'), where grades level into a broad meadow at the Grand Pass - Grand Lake Trail split (3.6 miles : 4,945').

The Grand Lake Trail switchbacks down to the west shore of Grand Lake (3.8 miles : 4,755'). The lake is ringed by thick timber, but with ample openings for anglers and exploration.

Access the north shore via the Badger Valley Trail (an alternative route to Grand Lake from Obstruction Point), or continue across the inlet to designated campsites.

Those with time should consider continuing on to Moose Lake (5,045') and Gladys Lake (5,372'), .7 miles and 1.2 miles from he Grand Lake Trail split, respectively.

Both lie in significantly wider berths in the valley with rangier views and rolling meadows to explore. The trail continues up to Grand Pass (6,450'), 1.45 miles from Gladys.

Worth Noting

  • Consider returning via the Badger Valley Trail, a longer but milder climb back to Obstruction Point. It receives lighter use and maintenance, so basic route finding skills may be necessary when overgrown.

  • Grand Lake and Moose Lake generally see much heavier day and overnight traffic than Gladys Lake, which is located 1.2 miles from the Grand Lake split. Backpackers should consider Gladys Lake for significantly more privacy with a competitive aesthetic.

  • Snow may linger and obscure portions of the trail well into summer. Steep, north facing slopes are a particular concern to hikers. Call ahead for trail conditions.

  • 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.
