Swim with the magnificent whale shark in the beautiful turquoise waters of the Caribbean Sea. The world’s largest species of fish, with their impressive size, create a visual spectacle as their dark grey bodies glide through the water. While swimming with these wonderful animals, you may see hundred-pound sea turtles, manta rays up to twenty feet and three species of dolphins, entertaining you with their playful swimming and corkscrew jumps.

Jacques Cousteau and John Steinbeck saw the magic that the Sea of Cortez has to offer. Jacques Cousteau called the Sea of Cortez “the worlds aquarium.” John Steinbeck wrote "The Log of the Sea of Cortez" a journey through a remote and beautiful corner of the world, a diary filled with the daily excitements and triumphs of skillful and energetic men. It is also an invitation to see the world anew from a fresh vantage point and perhaps with a broader and more understanding spirit. Dolphins, sea lions, pilot whales, humpback whale, blue fin whales, orca and sperm whales. Flying mantas, blue and brown footed boobie birds, cormorants, frigate birds and the endemic yellow footed gulls.

California’s Channel Islands offers some of the best natural beauty the world has to offer. Sunlight filtered by the canopy becomes an array of thin green-yellow splinters illuminating kelp fronds and fish immediately below. Juvenile calico bass and small kelpfish are well-camouflaged between brown kelp stripes and tangled blades. Small groups of sardines, almost invisible against the blue sky above, dart inches beneath the surface where the canopy clears. Slight surge rocks the entire forest gently back and forth.
