Ireland's dark sky preservation is amongst the best in the world.
Atlantic Clarity: The air coming off the Atlantic is exceptionally clean, though the accompanying clouds can be a challenge. Persistence is key. The Dark Sky Reserves: Ireland is home to two of the world's few Gold-Tier International Dark Sky Reserves—Kerry and Mayo. These offer skies as dark as the middle of the ocean.
