Snowdonia National Park, the largest of its kind in Wales, is also a recognized Dark Sky Reserve with out-of-this-world views. No, really—the Milky Way, vibrant nebulas, shooting stars, and a veritable constellation of other celestial bodies are all visible from this vast Welsh park. Once you’re done gazing at the heavens from Llyn Geirionnydd, Tŷ Cipar, or Bwlch y Groes, return by day to summit Snowdon, go castle-hopping, or visit the park’s other top sights.
