Cap Bon-Ami

At the far eastern reach of the Gaspé Peninsula in Quebec, Canada, the Appalachian Mountains crumble into the sea at white cliffs similar to Dover, England. This dramatic shoreline is literally the edge of the continent.
Housed inside the Parc National Forillon, it is protected by the Canadian Government and offers camping and hiking nearby. Climbing is prohibited but swimming is allowed, if you're willing to brave to cold northern waters.
