A complete loop of Thetis Lake can be completed in around 1 hour on foot, assuming ground conditions are good.
Located 10 kilometres (or 6.5 miles) west of Victoria, BC, Thetis Lake is split into Upper Thetis Lake and Lower Thetis Lake, connected by a narrow culvert. The 4.8 kilometre (or 3 mile) long main trail encircles both lakes, beginning and ending at the main beach near the parking area.
The trail can be shortened to a circuit of just one of the two lakes by returning via the Trillium Trail which intersects the middle of the lake.
