Wilderness AreaBudgetDark sky 5/5

Wood Buffalo National Park earned its dark-sky preserve designation from the Royal Astronomical Society of Canada in 2013 specifically because of how little artificial light exists across its 44,741 km2 — an area larger than Switzerland. The park's boreal-grassland ecosystem and Peace-Athabasca Delta are UNESCO-listed for their biodiversity, but for aurora travelers the headline is simply uninterrupted dark sky at a latitude (60°N) that sits comfortably under the auroral oval.
