Roque de Los Muchachos Astrophysical Observatory

Roque de los Muchachos Astrophysical Observatory sits high above La Palma’s cloud layer, with far-reaching views across the island and, on clear days, the Atlantic and neighbouring islands. See the astronomy instruments and learn about their history and purpose at the information center. A trail along the ridge adds a roughly three-hour walk beside views of the caldera. The observatory is a working research site, so access to telescopes can depend on conditions and activity.

At the observatory

The observatory is a research site for optical and infrared astronomy. Its telescopes include the Isaac Newton Telescope, the Swedish Solar Telescope and the Telescopio Nazionale Galileo. The information center explains the history and function of the instruments, giving you context for the facilities on the mountain.

This is an active observatory, so seeing a telescope in operation or getting access to particular areas depends on conditions and activity. Visitor access is also weather-dependent. Check conditions before making the trip.

Views from the ridge

A walking trail follows the ridge beside the observatory, with views down into the caldera. Allow about three hours for the hike and wear suitable shoes. On clear days, the views extend across the Atlantic towards Tenerife, La Gomera and El Hierro.

The drive up follows a narrow, winding road. Take care on the approach and allow time for the journey. Weather can change the experience at the summit, so check the forecast before setting out.
