Lac Carré is located in the Laurentians region of Quebec, situated at the heart of the village of Mont-Blanc. The lake sits within fishing zone 9 and is known to support lake trout (touladi), indicating reasonably good water quality and depth typical of Laurentian lakes.

The municipal beach on Lac Carré provides the primary public access point for paddlers. A boat launch ramp is available on site, accommodating both motorized and non-motorized watercraft. A boat and watercraft washing station is also present at the launch area. The beach facility offers free parking, a picnic area, toilets, and potable water on site. Access to the beach and launch is free of charge.

Kayaks and stand-up paddleboards are available for loan or rental at the beach, though this service operates on Fridays, Saturdays, and Sundays only, with conditions applying — paddlers should confirm details directly with lifeguards on site. The beach is staffed with lifeguards from noon to 6 p.m., seven days a week, from late June through Labour Day (early September). Supervision is not provided during poor weather conditions.

The lake is accessible for paddling during the summer season, with the municipal facilities operational from late June to early September. Paddlers bringing their own craft can use the boat launch independently of the rental schedule. The presence of a fishing boat launch suggests the lake accommodates a range of watercraft sizes, though paddlers should be aware that motorized boats may also be using the water.

Given its location within a village and its role as a community beach, the lake sees regular recreational use during summer months, particularly on weekends.
