Stargazing in Lisbon, Portugal

The Alqueva Dark Sky Reserve in the Alentejo (2 hours east) is one of the world's first certified Starlight Tourism Destinations. Lisbon's Bortle 6–7 skies improve heading south into the Algarve or east into rural Alentejo. Portugal's southern latitude (38.7°N) and generally dry conditions make it one of western Europe's better observing locations.
