What to bring on the tour:
  • 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 altitud.
  • Comfortable clothes and shoes are recommended (avoid sandals and high-heeled shoes). Climatic conditions could be extreme, moreover inside the telescopes the temperature is usually cold, therefore a coat is required even in summer.
  • A cap and sun cream are recommended, especially in summer.
Visitors health:

The Astronomical Observatory is situated at 2,400 m 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 anemia, 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 consequence of altitude or non-observance of our recommendations.

  • For your own safety, please follow your guide’s instructions all the time.
  • Punctuality is required. If you are late, you might lose 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 altitud 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.

  • 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 m a.s.l. than the sea level.

  • Be respectful with the environment: do not litter, please use containers provided.
