A 90-minute tour in one of the Roque de Los Muchachos telescopes with an official Starlight guide.

The tour takes place in two languages, normally Spanish and English.

The tours take place on TUESDAY, THURSDAY, FRIDAY and SUNDAY in the Roque de Los Muchachos in the municipality of Garafia at an altitude of 2400 meters.

After a brief presentation of the various telescopes and the quality of the sky on the island of La Palma, we will move to the assigned telescope: on Thursdays, we visit one of the English telescopes (WHT or INT), while the other tours are made in the Gran Telescopio Canarias (GTC). The official Starlight guide will explain the operation of the telescopes in La Palma, their main features, tools, scientific discoveries, maintenance work, some technical data and interesting news.
