    Directions to Trailhead

    Grand Pass Trail is a beast of a day hike, with over 22.0 km to cover across varied, steep terrain. This is a spectacular, hard day trip or a gorgeous backpacking adventure. Know that many day hikers complete a portion of this trail, often turning back before the steep descent (and subsequent ascent) into the valley at the end of the trail. This still allows you to enjoy the lakes dotted alongside the route and the changing terrain and views that make this trail enjoyable.

    Come prepared with lots of water, food, and good boots and poles.

    Route Description for Grand Pass Trail

    Grand Pass Trail is a jaw-dropping trek through Olympic National Park, passing deep blue lakes, mountains, and vibrant forest. It’s a demanding day trip, so most hikers either backpack it or shave off the trip into the valley at the end of the trail.

    Begin from the trailhead at the end of Obstruction Point Road. Take the trail on the right here, quickly climbing on top of a ridge. The terrain and views slowly evolve as you trek to the first junction, where you’ll stay left.

    Descend down to Grand Lake and Moose Lake, a popular spot for a mid-hike cooldown swim. Climb past little Gladys Lake and then ascend to one of the most difficult ridges of the hike. This section is boulder-clad and a bit tough to get through. On the other side of this ridge is a steep descent into the river valley. This is normally where day hikers call it quits, and if you want to continue, make sure you have lots of gas in the tank for the steep, rocky ascent back up from the valley floor.

    Retrace your steps to your campsite or the trailhead.
