Swan Lake Christmas Hill Nature Sanctuary is a nature reserve located in Saanich, British Columbia.[1] The sanctuary includes a lake, adjacent marshy lowlands, and the Nature House, as well as a good part of the summit regions of Christmas Hill.
The nature sanctuary consists of two physically and ecologically distinct areas: the low wetland area surrounding Swan Lake, and the rocky Garry oak-forested hilltop of Christmas Hill. The two areas are joined by a connecting corridor trail along the Nelthorpe Road allowance, crossing McKenzie Avenue at a pedestrian-controlled crosswalk. Portions of the corridor trail are on the roadside, and are identified by signs with a hiker symbol and arrow to indicate the direction.
The sanctuary land surrounding the lake covers 43.4 hectares (107 acres) in addition to the 9.4-hectare (23-acre) lake. In the winter flooding stage, the lake can cover up to 32.4 hectares (80 acres) of the low-lying lands around the lake.
