Dedicated to the conservation of the upper Gulf of California and surrounding Desierto Sonorense, CEDO has a visitor center where it hosts free natural-history talks in English at 2pm Tuesdays and 4pm Saturdays. CEDO also runs a fascinating program of nature tours, some in collaboration with local cooperatives.

Tours include tidepool walks (US$30), kayaking on Morúa estuary (US$75), snorkeling trips to Isla San Jorge (US$150) and excursions to El Pinacate Biosphere Reserve with an English-speaking naturalist (US$80).
