The Badger Valley Trail is located in the NE corner of Olympic National Park. This trail starts at the Obstruction Point Trailhead and trends down into Badger Valley to end at Grand Lake.
Start out traversing steep open slopes for 0.3 miles on the Deer Ridge Trail before descending at a quicker clip on several switchbacks on the official Badger Valley Trail. The trail then levels off to traverse the slopes above the valley, following it downhill.
At the bottom, the route hangs a right and follows Grand Creek to Grand Lake, crossing the creek a couple times along the way. At Grand Lake you can continue on to two other lakes, Moose and Gladys, another mile farther.
The Badger Valley Trail officially ends at the outlet of Grand Lake. Hikers can turn around here and head back the way they came or return via the Grand Pass Trail on the Grand Valley Loop.
