The northern Gulf area forms an impressive desert-coast ecosystem, and scientists conduct research programs at the Intercultural Center for the Study of Desert and Oceans (known as CEDO, its acronym in Spanish), about 3 km (2 mi) east of town on Fremont Boulevard in the Fraccionamiento Las Conchas neighborhood. You can take an English-language tour of the facility to learn about the ecology of the area and its history, or just pick up a tide calendar (useful if you're planning beach activities) or field guide from the gift shop. Talks and nature outings—including tide-pool walks, Pinacate volcano excursions, and kayaking expeditions of area estuaries—are on offer.
Turn onto Blvd. Fremont at municipal building and follow signs for Las Conchas Beach and CEDO, Puerto Peñasco, Sonora, 83550, Mexico
