The Garibaldi Ranges are the next-to-southwesternmost subdivision of the Pacific Ranges of the Coast Mountains; only the North Shore Mountains are farther southwest. They lie between the valley formed by the pass between the Cheakamus River and Green River on the west (the location of the Resort Municipality of Whistler) and the valley of the Lillooet River on the east, and extend south into Maple Ridge, an eastern suburb of Vancouver, and the northern District of Mission.
