Acadia National Park runs an annual multi-day Night Sky Festival, with a signature star party on Cadillac Mountain — one of the first places to see sunrise in the US, and, on the right nights, a genuinely dark spot on the Maine coast.

Drive from Toronto: Via ME-3 onto Mount Desert Island, near Bar Harbor, ME.

Best time of year: The Acadia Night Sky Festival runs each fall (typically September); outside the festival, check current Park Loop Road access hours before planning a summit visit.
