La Palma is an island of considerable ecological interest with over 20 protected areas, including one of the Canary Islands’ four national parks, an extensive marine reserve, natural reserves, and sites of special scientific interest.
Those fond of astronomical navigation may well be pleased to hear that La Palma is one of the world’s best locations for stargazing and home to the world’s first international Starlight certification (as both a Starlight Reserve and Tourist Destination). The “Sky Law”, in place now for over 30 years and also the first of its kind, protects the quality of the night sky, mitigating light and atmospheric pollution around the island and reducing the harmful effects of nocturnal illumination on birds, animals and insects.

A visit up to the Roque de los Muchachos, the island’s highest peak at over 2426m, offers spectacular views of the interior of the Caldera de Taburiente, as well as renowned international astronomy site, the Roque de los Muchachos Observatory. The impressive array of equipment includes the Gran Telescopio Canarias (GTC), and the Large Size Telescopes Chernenkov LST-1 in place since 2018, amidst some twenty other telescopes from a wide variety of international institutions. Visits to some of the facilities are possible using official guides. Follow this link for more information https://www.iac.es/en/observatorios-de-canarias/roque-de-los-muchachos-observatory
