Introduction:

On the island of La Palma, at 2,396 meters of altitude, is situated the Astronomical Observatory of El Roque de Los Muchachos (ORM): a worldwide prestigious scientific research center, housing an advanced set of telescopes, among which the Gran Telescopio Canarias is the main highlight, currently the largest optical-infrared telescope in the world.

Guided tours are carried out into one of the telescopes, only in the mornings. Prior booking is strictly required. Night-time tours are not allowed at ORM. For stargazing tours with amateur telescopes from astronomical viewpoints on the island, please click on this link.

What to bring on the tour:
  • It is not necessary to print your ticket (please, show it to the guide from your mobile phone).
  • At the ORM there are no shops or vending machines to buy any water or food. We recommend you bring snacks or nuts and plenty of water or juice to avoid dehydration, due to low humidity levels at this altitude.
  • Comfortable clothes and shoes are recommended (avoid sandals and high-heeled shoes). Climatic conditions could be extreme, moreover, inside the dome of the telescopes the temperature is quite low (a thermal conditioning system is used at any time of the year), therefore a coat is required even in summer.
  • A cap and sun cream is recommended, especially in summer.
Visitors health:

The Astronomical Observatory is situated at 2,400 meters a.s.l., consequently oxygen level is lower than the AT sea-level. For this reason, we do not recommend this tour to babies, people with anaemia, heart diseases, breathing problems and people over 70.
In case of appearing symptoms of dizziness, nausea, shortness of breath or headache, please inform your guide immediately.
Medical assistance is NOT available at the ORM.
We are not responsible for any health damage as a consequence of altitude or non-observance of our recommendations.

Warnings:
  • Remember to check your email and mobile phone on the same day of the tour before going to the Observatory, in case of last minute notice.
  • For your own safety, please follow your guide's instructions all the time.
  • Punctuality is required. If you are late, you might miss the tour and your ticket will not be refunded. Please, calculate the required transfer time: LP-4 is a tortuous mountain road, so possibly you will need to make some stops along the way, in case of dizziness due to altitude and pressure change. Anyway, maximise precautions and drive carefully.
  • It generally takes:
    1h 15m from Santo Domingo de Garafía, Puntagorda and Santa Cruz de La Palma.
    1h 30m from Los Cancajos, Parador Nacional de Turismo, Los Llanos de Aridane, Tazacorte and Barlovento.
    1h 45m from El Paso, San Andrés y Sauces and Villa de Mazo.
    2h from Puerto Naos.
    2h 15m from Fuencaliente.
  • There are no gasoline pumps at the ORM, so it is recommended to fill the tank before the trip. Please, take into account that the fuel consumption is usually bigger at 2,400 meters a.s.l. than the sea level.
  • Smoking is not permitted inside the buildings and in public areas.
  • Be respectful with the environment: do not litter, please use containers provided.
