Thetis Lake is a name that refers to two freshwater lakes (Upper and Lower Thetis) connected by a narrow culvert in the 834-hectare (2,060-acre) Thetis Lake Regional Park outside Victoria, British Columbia, about 12 km (7.5 mi) from the city centre. The lake was likely named for the frigate HMS Thetis,[2] which had been assigned to Esquimalt as part of the Royal Navy's Pacific Squadron. The two lakes are extremely popular as a swimming destination in the summer.
It was established as Canada's first nature sanctuary in 1958. The park's facilities include several beaches, kilometres of forest trails, parking, washrooms and a change room. The area features many Garry oak and Douglas fir trees. [3]
