Foley Lake serves as an alternative starting point for hikers attempting the Williamson Lake Trail in British Columbia's Cheam Range, near Chilliwack Lake Provincial Park.

Drivers without a 4x4 or high-clearance vehicle can park near Foley Lake and cover the additional distance on foot to reach the official trailhead, which sits at the end of Foley Creek FSR.

The trail itself is a challenging out-and-back route of roughly 6 kilometres, climbing steep terrain through forest and alpine meadows before arriving at Williamson Lake. The best conditions are typically found between July and September.
