Le Castor is a campground located within Mont-Tremblant National Park in Quebec, situated near Lac Monroe at an elevation of roughly 1,150 feet.

The campground offers 61 dirt-pad sites, accommodates tents, and is open seasonally from late April through October. Reservations are accepted.

Sites are set among a thick canopy of trees with densely forested buffers between them, providing a notably private and quiet atmosphere. The proximity to Lac Monroe makes it easy to access the beach and catch sunrise over the water.

The surrounding park offers ample opportunities for hiking, kayaking, and mountain biking.
