Cala d'Hort observatory

The Ses Païsses de Cala d'Hort Astronomy Observatory sits in Sant Josep de sa Talaia, on the island of Ibiza, Spain, close to the famous Es Vedrà islet.

About Cala d'Hort Observatory

The observatory was adapted from existing installations at the Ses Païsses de Cala d'Hort Ethnographic Museum. It is managed by the Ibiza Astronomy Group, while the Island Council, the Consell d'Eivissa, handled its construction and operation, making it a genuinely public facility on the island.

Telescopes & research

The site houses three telescopes, including a 0.5-metre aperture instrument acquired in 2020, capable of showing visitors galaxies, nebulae, and planets alongside more familiar targets. An electronically operated sliding ceiling opens the dome to the sky, and two dedicated cameras are used to observe and detect meteors.

Location & getting there

Cala d'Hort Observatory is located in Sant Josep de sa Talaia municipality, in southwestern Ibiza, near the striking silhouette of the Es Vedrà islet just offshore — one of the most photographed viewpoints on the island.

Visiting Cala d'Hort Observatory

Observation sessions are free, though pre-registration is mandatory, and each session is capped at a maximum of 30 people. Check current schedules through the Ibiza Astronomy Group or the island's tourism channels before planning a visit, as sessions fill up.
