The 140 metre long Swan Lake and Brett trestles are railway bridges, which span a flood plain and a creek that joins Blenkinsop and Swan Lakes.

Built between 1915 and 1917, the Swan Lake and Brett trestles are valued as two of the few remaining trestles on southern Vancouver Island, and the last in Saanich. As such, they represent a unique and significant part of Saanich's industrial heritage, and are physical reminders of the role that the Victoria and Sidney Railway, B.C. Electric Railway, and the Canadian Northern Pacific Railway had in establishing many of the communities throughout the Saanich Peninsula.

The Lochside Trail is a picturesque 29 kilometre multi–use trail, a formerly a railway line that stretches from Swartz Bay to Victoria, past beaches, farmland, and wetlands, down country lanes and beside suburban backyards. The trail has a more civilized personality than its more rural cousin, the Galloping Goose Regional Trail. While some parts of the Lochside Trail are off-road and others downright pastoral, in some places trail visitors must share paved or gravel public roads with motor vehicles and farm vehicles.

The Lochside Trail intersects with the Galloping Goose Regional Trail and Trans Canada Trail just north of Victoria. They continue the tradition of a regional transportation network from the core of Saanich to downtown Victoria.
