Lac Stukely is a natural lake of approximately 4 square kilometres located in the Eastern Townships region of Quebec, Canada. It measures 5.3 km in length and up to 1.6 km in width, with a maximum depth of 32 metres. The lake sits at an elevation of 285 metres and is bordered by the municipalities of Orford, Bonsecours, and Eastman. A substantial portion of its eastern shoreline — roughly 12 km — falls within Parc national du Mont-Orford, which encompasses two sectors: the Lac-Stukely sector and the Jouvence sector. The lake is framed by the Mont Orford and Mont Chauve ranges, providing panoramic views from the water.

The primary access point for paddlers is the Plage du Lac Stukely within the Lac-Stukely sector of the park. A drop-off zone with 10- and 15-minute parking is located at the end of the parking area near the lake. Water access is via the beach, outside the supervised swimming zone, near the Bonnallie service centre. A boat launch for small craft is also available within the park. Entry requires a SEPAQ access pass, which can be reserved online in advance, along with a parking vignette — both are recommended during busy periods. The beach area has a capacity of 2,500 people and frequently reaches it, so advance reservation is advisable.

On-site facilities at the Bonnallie service centre include washrooms, Wi-Fi, a convenience store, and a boutique. Boat rentals are available, including canoes, kayaks, pedalos, SUP paddleboards, and small boats, with daily rental prices ranging from approximately $40 to $65. The campground within the Lac-Stukely sector offers 358 sites, some of which are lakeside, making it a practical base for multi-day paddling trips. Dogs are not permitted at the picnic area or on the supervised beach, though they are allowed on a leash on the boat rental side of the lake.

The lake lies at the head of the Saumon River watershed, which gives it a relatively long water retention time for its size. The surrounding park also offers extensive hiking trail networks, with trailheads accessible from the same service area used by paddlers.
