Marmot Pass - Tubal Cain - 16.0 Miles Round-Trip
Marmot Pass (5,950') is located on the south shoulder of Buckhorn Mountain (6,988') along a divisive ridge between the Big Quilcene River headwaters (east) and Dungeness River (west). The pass is accessible by routes of varying distance and difficulty from the Upper Big Quilcene, Upper Dungeness and Tubal Cain trailheads in the Buckhorn Wilderness.
The Tubal Cain Trail runs south through the Copper Creek Valley up to Buckhorn Pass (5,865'), then wraps around the west side of Buckhorn Mountain to Marmot Pass. This longer but more moderate route features lengthy alpine ridges, airy meadows and access to Buckhorn Lake:
The Tubal Cain Trail heads south past several backcountry campsites and the Silver Creek Shelter before turning west and south again into Copper Creek Valley (.5 miles : 3,395').
Travel and trail conditions change little over the next 2.5 miles up the east side of Copper Creek. This well-maintained segment runs under a moss-draped canopy lined by dense rhododendron and salal. Views are quite limited, but occasional breaks offer a glimpse of things to come.
IMPORTANT: The trail reaches a major unmarked split at the 3.0 mile mark (4,240'). Stay right to remain on the Tubal Cain Trail; the left fork leads into a confusing plot of campsites and on to an historic mining area.
Stay right and cross the creek to the west side of the valley (3.2 miles : 4,290'). The correct path continues past a small campsite on the right once over the creek.
Steep switchbacks rise up the west valley wall (3.5 miles : 4,470') as montane forests give way to open slopes and meadows (4.0 miles : 4,750'). Keep straight at the split for Buckhorn Lake (5.0 miles : 5,185').
The trail scales another set of switchbacks along exposed, east-facing slopes (5.5 miles : 5,480') before moderating on the final push to Buckhorn Pass (6.2 miles 5,865').
It continues south over Buckhorn Pass and rises steeply up the west side of Buckhorn Mountain (7.5 miles 6,515'). The final segment, which is fully exposed and subject to strong winds and white out conditions, drops over 500' to Marmot Pass (8.0 miles : 5,950').
Visible peaks include Mount Deception, Mount Mystery and Mount Fricaba. The trail continues down the pass to a connection with the Dungeness River Trail, and across the Olympic National Park Boundary to Home Lake and Constance Pass.

Worth Noting
- Fires are not permitted at Buckhorn Lake, and there are no reliable water sources above the lake. Consider water access when planning your trip.
- Mountain Goats inhabit the Buckhorn Wilderness, and are attracted to salty smells like sweaty clothing and human waste. Keep a clean camp, follow waste disposal guidelines and maintain a safe, respectful distance from wildlife.
- The trail continues over Marmot Pass into Olympic National Park. NPS rules and camping permit requirements apply within park boundaries, regardless of your starting point.
