La Société d'aménagement de la baie Lavallière
This non-profit society provides an excellent introduction to the Lac St-Pierre archipelago. Guided excursions on board a motorized canoe allow you to observe the reserve's amazing biodiversity in the company of a naturalist. Tours last at least two hours and depart from the Maison du Marais. Reservations required. In operation from late May through late August.
