Poisson-Blanc Regional Park, Regional park in Notre-Dame-du-Laus, Canada.

Poisson-Blanc Regional Park is a protected area in the Laurentian Mountains featuring a large reservoir surrounded by forested shores, rocky cliffs, and scattered islands. The water is the focal point, with peninsulas and islands creating a complex landscape of bays and passages to explore.

In 2002 the creation of a regional park at Notre-Dame-du-Laus was already under study, and the Corporation du Parc du Poisson Blanc was formed in 2005. Organizers drafted a plan to develop the lake's islands, and in 2006-2007 three technicians coordinated a cleanup that removed about two tons of waste left on the islands, installing latrines on several of them. The park was officially created in 2008, island campsite reservations began in 2009, canoe and kayak rentals were added in 2010, and the Le Bastion reception pavilion opened at the start of the 2012 season.

The park's name comes from the white fish caught in the lake and river. Since 2009, campers have reserved sites on the islands, and the park maintains 17 picnic stops there. Canoe, kayak and paddleboard rentals started in 2010 at Le Bastion pavilion.

The park is open year-round. Hiking trails on Fort Mountain are reachable by car from the Rapide-du-Fort and Lac Cuillèrier parking areas, while island trails require a boat. Canoe, kayak and paddleboard rentals are available at the Le Bastion reception pavilion in Notre-Dame-du-Laus; access from the south is via Bowman/Denholm, where boats can be rented at the Air-Eau-Bois outdoor base.

The park features a network of isolated camping spots distributed across multiple islands, reachable only by water from the mainland. These island camps offer a rare chance to spend several days completely surrounded by water and forest with no road access.
