South Bruce Peninsula.

South Bruce Peninsula occupies the south end of the Bruce Peninsula between Lake Huron and Georgian Bay, anchored by Wiarton on Colpoy's Bay and Sauble Beach on the Lake Huron shore. Sauble Beach runs roughly 11 km of sand along the Lake Huron coast — widely cited as one of the longest freshwater beaches in the world — with formally protected piping plover nesting habitat in the dunes.

Inland and to the north, the Bruce Trail's Peninsula Section climbs the Niagara Escarpment cliffs above Colpoy's Bay through Spirit Rock Conservation Area, where a stairway descent passes the 1881 Corran estate ruins. Sauble Falls Provincial Park protects a stepped limestone cascade on the Sauble River where Chinook salmon spawn in September and October.

Bluewater Park on the Wiarton waterfront hosts the annual Wiarton Willie groundhog ceremony every February 2. The town sits within Saugeen Ojibway Nation traditional territory; a few hours from the GTA via the major highway corridor through Owen Sound.
