Let yourself be guided across celestial wonders. All you have to do is look up. Whether you’re interested in an introduction to astronomy or you are an experienced observer, join us where the earth meets the sky.

Céus do Sul is a mobile astronomical observatory that travels along the dark skies of Portugal’s Algarve and Alentejo regions, well worth a night out. With a latitude of 37º the Algarve exposes constellations that are not visible from more northern horizons. Spend your holidays stargazing with us!
