The Grand Canyon became an International Dark Sky Park in 2019, and it's one of the great stargazing experiences anywhere — the same rim that gives you a two-billion-year view down into the canyon by day gives you an equally deep view up into the sky by night.
Drive from Toronto: Fly into Phoenix or Las Vegas, then drive 3.5–4.5 hours to the South Rim (Flagstaff is the closer regional hub).
Best time of year: New moon, especially during the park's annual summer Star Party.
