From hiking to boating to biking to camping, the Grand Canyon National Park is as astonishing as it gets. Descend below the rim and the sense of awe only grows. Stargazing in the Grand Canyon is also a special experience. In summer 2019, the park was designated as an International Dark Sky Park by the International Dark-Sky Association. Every June the national park hosts &lsquostar parties&rsquo with telescopes set for free use, in addition to astronomer talks and photo workshops.
