Roque de los Muchachos and La Palma

The Roque De Los Muchachos Observatory At 2,400 Metres, Opened 1985, On La Palma A UNESCO Biosphere Reserve And The World'S First Starlight Reserve, Protected By Spain'S 1988 Sky Law · Garafia, Canary Islands

One of the best places on earth to look at the sky, and protected by law for it. La Palma sits far enough out in the Atlantic to escape almost all light pollution, and the trade-wind inversion layer parks a sea of cloud a thousand metres below the summit, so the observatory on the Roque de los Muchachos at 2,400 metres is above the weather for most of the year. That combination is rare enough that a dozen countries have built telescopes here, including one of the largest optical telescopes in the world. Spain passed a Sky Law in 1988 to protect the seeing, which restricts lighting across the island, and La Palma was the first Starlight Reserve anywhere. The rest of the island is a steep, wet, green volcanic ridge with a vast erosion caldera in the middle. In 2021 the Tajogaite eruption ran for eighty-five days and buried villages on the western slope, which is recent, visible and should be treated as a living place rather than a viewpoint.
