Mingan Archipelago National Park Reserve protects a chain of limestone islands and granite islets just offshore from Havre-Saint-Pierre. The famous shapes are the monoliths: pale sea-stacks carved by waves and frost, standing above low spruce, shore plants, and cold Gulf water.
This is the one sight here that is worth planning around. Boat excursions reach different islands depending on weather and season; the best trips give you time to walk among the monoliths, watch seabirds, and understand why the landscape feels more northern than the map first suggests.
