Through a Glass, Darkly: Typical city skies rate an 8 or 9 on the Bortle Dark-Sky Scale, the astronomer’s yardstick of darkness. Jasper National Park ranks as a 1 or 2, which means that features usually seen only through a telescope become visible with the naked eye, such as the Andromeda galaxy and all seven sisters of the Pleiades star cluster.
From Dawn to Dusk: When you’re not stargazing, try your luck at wildlife watching (including caribou) along more than 600 miles of hiking trails at the park. Feeling brave? Take a stroll on the new glass-bottom Glacier Skywalk that’s suspended 918 feet above a canyon.
Go: Jasper National Park Dark Sky Preserve is about 200 miles west of Edmonton and the nearest commercial airport. There’s also train service to Jasper from Vancouver and Edmonton, if you want to travel the scenic way. For those without a car, Tourism Jasper offers free shuttles from town to some of the festival’s events. Just make sure to bundle up: October nighttime temperatures can dip below freezing.
Go Deeper: Want more? Whether daytime sightseeing or nighttime stargazing, take a drive to Pyramid Island, Maligne Lake or Athabasca Glacier. Just make sure to check the astronomer’s forecast for “Jasper Maligne Lake” or “Jasper Athabasca Glacier” for a peek at cloud cover and transparency, as well as sun and moon data, before you set out.
