Welcome to the Intercultural Center for the Study of Deserts and Oceans.

Join us to explore, understand, and protect the natural resources and cultures of the Sonoran Desert and Sea of Cortez. Our mission is to bring together people, knowledge and solutions for vibrant communities AND resilient ecosystems, in the northern Gulf of California and beyond.

By promoting environmental awareness, disseminating knowledge and encouraging civic participation, CEDO is a fundamental force driving civic dialogue and transparent decision-making. CEDO has been the promoter of a vision:  the vision of an open, participatory society  consciously building its own future.

CEDO Nature Talk @ CEDO Intercultural
Aug 27 @ 2:00 pm – 3:30 pm

A well-known local tradition since the 1980’s, CEDO holds a natural history talk and exhibits tour every Tuesday and Saturday. This is a perfect opportunity to answer your questions about the local environment. Bring your family to learn about the Gulf of California’s extreme tides, the endangered vaquita porpoise and CEDO’s current projects.


Tidepool Exploration / Exploración a las Pozas de Marea
Aug 31 @ 7:00 am – 10:00 am

When tides are at their lowest, a vast and dynamic ecosystem gets exposed.

Tidepooling during a full moon is the perfect opportunity to both be amazed by the nocturnal sky’s beauty and discover very unique hidden creatures during low tide. Join us as we explore the rocky intertidal reefs of Puerto Peñasco in search of marine invertebrates like sea slugs, sea hares, starfish, sea anemonies, pistol shrimp, and many more mysterious species that get caught in these pools of saltwater as the tides recede while the full moon shines brightly in the dark sky.

For more information please check our EcoTour calendar @www.cedo.org, email us at info@cedo.org, or call us at +01 52 (683) 638-0113.


¡Cuando la marea baja un mundo queda al descubierto!

Acompáñanos a descubrir la asombrosa variedad de organismos que habitan en una de las zonas intermareales de puerto peñasco en búsqueda de especies como peces, cangrejos, estrellas de mar, anemonas ¡y mucho más!

En el tour estarás siempre acompañado por un guía naturalista experto, quien te enseñará sobre el comportamiento de estas maravillosas criaturas, la importancia de su ecosistema y los factores asociados a las mareas extremas, en donde las interacciones entre el Sol, la Luna y la Tierra juegan un rol muy importante.
