Lac Provost is located within Parc National du Mont-Tremblant in Quebec's Laurentides region, approximately 1.5 hours by car from Montreal. The lake covers roughly 616 acres with about 8.8 miles of shoreline, placing it in the Matawinie district near communities such as Saint-Donat-de-Montcalm. The water is reported to be clean and clear, with no current, as expected of a lake environment.

Motorized boats are not permitted on Lac Provost, which keeps conditions calm and makes it well-suited for paddling at all skill levels. The main Lac Provost Beach — offers a sandy launch point along with picnic tables, seasonal bathrooms, and a rental center where kayaks, canoes, SUPs, and pedalos are available. A second access point, Plage du Domaine Rouge, provides an additional launch option. A smaller, quieter beach also exists near the "Les Chalets en Nature" area, listed on Paddling.com as a sandy beach launch with free parking. Park entry fees apply through SEPAQ (the provincial parks authority); as of recent reports, adult entry is around $10, which covers access to the broader Mont-Tremblant National Park network. Paddle board rentals, if needed, run approximately $50 for a full day.

The lake is surrounded by forested terrain typical of the Laurentians, and wildlife sightings — including loons and beavers — are commonly reported. The absence of motorized watercraft contributes to a quieter paddling environment. The main beach area is supervised and sees regular visitor traffic, particularly in summer, while the smaller beach near Les Chalets en Nature tends to be less crowded.

Because Lac Provost sits within a national park managed by SEPAQ, paddlers should verify current park regulations and any seasonal access restrictions before visiting. No restaurants are located directly at Lac Provost Beach, though dining options exist in the surrounding area. Paddlers bringing their own craft should confirm current rules regarding personal watercraft, as park policies can change.
