Two Oceans, One Day: Snorkeling Sea Lions and Swimming with Whale Sharks off Espiritu Santo
9 hours • Ages 5+ for public tours • All ages for private tours
The boat slips away from Marina La Paz at first light and the city folds into the horizon like a watercolor left to dry. Salt and diesel mix on the breeze; the captain steers a line of white toward the islands that puncture the Sea of Cortez. For the next nine hours you’ll move between two very different currents of life: a frenetic colony of sea lions that treats the ocean like a playground, and the slow, deliberate world of the whale shark, whose stripe-patterned flank glides beneath you like a moving reef. This is the rhythm of the Combo Tour — a day designed to deliver close encounters without crowding the animals.
Trail Wisdom
Arrive Early
Parking at Marina La Paz fills quickly; arrive 30–45 minutes before departure to check in and get fitted for gear.
Bring Reef-Safe Sunscreen
Although biodegradable sunscreen is provided, bring your own if you have a preferred brand to protect coral and skin.
Practice Your Snorkel Skills
Spend a few minutes in shallow water to remove mask fog and practice breathing—confidence in the water improves your encounter.
Respect Distance Rules
Only enter the water when instructed and keep the mandated distances from animals to avoid stressing wildlife.
