Hikers can climb up to the ridge between the East and West Lion peaks using either the Binkert Trail leading up from Lions Bay, or the Howe Sound Crest Trail. The Binkert Trail, named after Paul Binkert of the British Columbia Mountaineering Club, is one of the most popular in the Lower Mainland. Hiking to the ridge from Lions Bay takes approximately four hours and gains in elevation. Most hikers stop there as both the East and West Lion peaks require rock climbing equipment and expertise. The East Lion is out-of-bounds for climbing as it is located in the Greater Vancouver watershed.
Early ascents
According, to an article by Steven Threndyle in The Greater Vancouver Book, "the earliest recorded climb of the West Lion in 1889 happened almost by accident. A group of hunters following a herd of goats found themselves at the top with no place to go but down. The hunting party was guided by Squamish First Nations Chief Joe Capilano. One of the members of the hunting team was Doctor Henry Bell-Irving, who asked Chief Capilano if he could time one of the chief's young natives to see how long it would take him to run from the base of the West Lion to the summit. The youth stripped completely naked, made the round trip ascent and descent in under 20 minutes. With its steep granitic face, the East Lion was believed to be impossible to scale. That did not deter John Latta and his two brothers from setting out to climb the East Lion in 1903. Hearing that climbers often used ropes for mountaineering ascents, they packed one along but actually had no idea of how to use it. Their technique was to grasp the small shrubs and bushes growing out of the cracks in the rock. The Latta brothers also climbed the West Lion on their way out.
"The Sisters"
The Indigenous Squamish people named these two prominent peaks "Ch'ich'iyúy Elxwíkn". These mountains remain sacred for their legal marker of a peace treaty, family lineage histories, and spiritual value. The two peaks were transformed by the Sky Brothers, or Transformers, after twin sisters that had married with Haida twins created the path for the war to end between the Squamish and Haida people. The families that made the Peace Treaty and married together still live in the Squamish and Haida Nations. Sometime around 1890, Judge John Hamilton Gray proposed that Canada rename the mountain peaks to lions couchant from heraldry.
