CEDO, the Intercultural Center for the Study of Deserts and Oceans, sits on a bluff over Las Conchas beach in Puerto Peñasco and combines a small natural history museum with active marine research and conservation programs focused on the northern Gulf of California. The free exhibit hall covers the ecology of the Sonoran Desert and the Sea of Cortez, including displays on the endangered vaquita porpoise and the intertidal life found on the nearby rocky shore, while the center's scientists lead scheduled guided tours of the tidepools and the estuary at low tide, pointing out species and explaining the tidal dynamics that make this stretch of coastline unusually productive. A visit runs one to two hours for the museum alone, or longer when combined with a guided tidepool walk, which typically takes 90 minutes and follows the tide chart rather than a fixed daily time. The center is best experienced by checking the posted tide schedule in advance and timing arrival to catch a low-tide tour, since the tidepools are only exposed and safely walkable during that window. Weekday visits tend to be less crowded than weekend mornings, when local families and visiting groups from Puerto Peñasco hotels often book the tours. CEDO also runs sea kayaking and full moon tours seasonally, which can be booked directly through the center.
