Tahla Lake is a small backcountry lake in British Columbia's Kane Valley area near Merritt, sitting at roughly 3,370 feet elevation.

It is home to a provincial recreation site offering around five primitive campsites with tables and pit toilets, suited for tent camping with a maximum 14-day stay. The lake is popular for rainbow trout fishing and connects to nearby hiking trails.

Two main access routes serve the site: one via Highway 97C to Coalmont Road and then Voght Valley Road, passing Davis Lake and Boss Lake before reaching the Tahla Lake turnoff; the other via the Coldwater exit off Highway 5, then Kane Valley Road and Voght Valley Road to the same destination.
