Au Diable Vert is a four-season mountain resort and campground near Glen Sutton in southern Quebec's Eastern Townships, situated in the North Missisquoi River Valley between the summits of Round Top and Jay Peak.

Its 19 rustic campsites are spread well apart and accessible only on foot, each equipped with a sand or wood platform, fire ring, and picnic table. Views stretch across the Missisquoi Valley to Vermont's Green Mountains.

Water, sanitary facilities, wood, and ice are available on site. Designated a Dark-Sky Preserve in 2018, the property protects mature maple groves older than 80 years and lies within the range of one of Quebec's largest populations of threatened wood turtles.

Outdoor activities include stillwater kayaking on the Missisquoi River, hiking, snowshoeing, and the VéloVolant — a treetop pedal-powered aerial course billed as the highest of its kind in the world.
