Details and Pricing

Lift your eyes towards the sky and let the canopy of stars inspire your journey!

Recently certified as a Canadian Dark Sky Preserve, the enchanting Au Diable Vert site allows you to discover the canopy of stars. Located in Glen Sutton, come discover a novel and intriguing world through this innovative activity, that combines the technology of several cutting-edge companies from around the globe.

Cradled in heated stadium seats, and perched at over 1,000 feet of altitude, this open air spectacle takes place in a multilevel mountain side amphitheater in Quebec’s newest Dark Sky Preserve at Au Diable Vert in Sutton, Quebec.

Every guest will get to use a newly developed augmented reality headset created by Aryzon in the Netherlands, which will allow them to see the actual night sky, with a digital overlay of the constellations and the names of stars and planets.

Combine your tour through the sky with a stay in one of Au Diable Vert mountain view suites, rustic cabins or tree houses and enjoy some of the other activities like kayaking or VeloVolant.
