Built with salvaged timber, Lake Huron's two-year-old, six-suite E'Terra Inn is almost as pristine as its Georgian Bay surroundings. The LEED Gold–certified resort sits on the eastern shore of Lake Huron, in the Niagara Escarpment Biosphere Reserve. The water in the bay is so clean that guests drink it regularly, and kayakers can see 20 feet to the lake floor.
The resort is entirely free of electromagnetic fields (read: there's no Wi-Fi or cell service).
Three hours from Toronto. Doubles, $430; eterra.ca
