Swimming with Giants: Whale Sharks and Sea Lions in Espiritu Santo
7 - 8 Hours • All Ages • Starting at $250 USD (converted to Pesos at checkout)
The boat slips away from La Paz’s crescent bay before sunrise and the city’s pastel buildings blur into the long, calm throat of the Gulf of California. Salt tastes fresh on your lips, the engine hums into a steady rhythm, and the first gift of the morning arrives—a spray of flying fish rebounding off the bow as if to test your resolve. Out here, the water is a phenomenon in motion: glassy flats give way to pockets of turquoise and almost-electric blue where currents upwell, and the horizon is the promise of animals you’ve only seen in documentaries.
