Northumberland National Park, U.K.

Northumberland National Park is home to some of England’s cleanest rivers, clearest air, and darkest skies, located in Northumberland, just 56 miles (90 km) southeast of Edinburgh, Scotland, and about 60 miles northwest of Newcastle-upon-Tyne, England. It’s an accredited dark sky park, called “a bulwark against the incursion of harmful light pollution” by the International Dark Sky Association. Frequent public stargazing events organized by park authorities or run by local astronomical societies are hosted here; the semiannual Kielder Starcamp attracts many amateur astronomers. Please note that while camping is allowed, there are a variety of esteemed dark sky sites to choose from. For reservations, visit online or call 44 (0)1434 605555.
