Things to Do in San Carlos
The Sea of Cortez is a marine biosphere. The desert has canyons with palm oases. The mountains have trails with panoramic views. San Carlos keeps finding new ways to earn the Cousteau quote.
San Carlos is not just pretty beaches. It is the world's aquarium according to Jacques Cousteau, with marine biodiversity that competes with the best dive destinations on the planet. But there are also desert canyons with palm oases, peaks with panoramic views, and world-class sport fishing.
The most efficient half-day in San Carlos: hike Nacapule Canyon in the morning (start before 8 AM, finish by 11 AM before the heat peaks), then drive 10 minutes to Bahía San Francisco for snorkeling and lunch. Two completely different ecosystems — desert oasis and turquoise sea — back to back. Nobody who does this regrets it. .
