Mt. Bretherton is located in the southeast corner of Olympic National Park in the Olympic Mountain range. Mount Bretherton is situated one mile south of Upper Lena Lake. While not of serious climbing importance, the summit offers good views of The Brothers approximately 5 miles to the northeast, Mt. Stone 4 miles west, Mt. Lena 2 miles north on the opposite shore of Upper Lena Lake, and many other peaks of the southeastern corner of the range. The peak was named in 1890 for B.J. Bretherton who was a naturalist and member of the Lt. O'Neil Olympic Mountain Exploring Expedition.
From Highway 101, follow the Hamma Hamma River Road to the Lena Lake Trail (trailhead elevation ~ 700 ft). Hike 3 miles along the trail until reaching Lena Lake at about 1800 ft. At the lake the trail splits, the right taking you to the lake and to The Brothers route, the left continues upward along trail to Upper Lena Lake at about 7 miles and 4600 feet elevation and good campsites around the lake. Mt. Bretherton is the peak above the south shore of this lake. From Upper Lena Lake follow a path south to Milk Lake to gain access to a ridge to the summit. There is loose sedimentary and rock and shale on this scramble.
Refer to Olympic Mountains: A Climbing Guide, by Olympic Mountain Rescue, for information on the established climbing routes on Mount Bretherton.
