The Marine Sanctuary of Lima
Escape the city and embark on a thrilling half-day marine wildlife expedition into the nutrient-rich waters of the Pacific Ocean. Just off the coast of Lima and the historic port of Callao lies the protected Cavinzas and Palomino Islands National Reserve—an extraordinary marine sanctuary ideal for couples, families, and wildlife enthusiasts.
Departing from Callao Harbor aboard a stable cruiser yacht, you will navigate past San Lorenzo Island toward the rocky outcrops of the Palomino Islands. Along the way, your naturalist guide will point out colonies of Peruvian boobies, Guanay cormorants, Inca terns, and endangered Humboldt penguins. At the Palomino Islands, equipped with a thermal neoprene wetsuit and lifejacket, you will have the unforgettable opportunity to enter the ocean and swim safely alongside thousands of playful, wild South American sea lions. Combine this morning ocean adventure with an afternoon Historic Lima City Tour, our Larco Museum & Huaca Pucllana Experience, or continue south to Paracas & the Ballestas Islands.
