Board a Bertram yacht in Callao for a three-hour outing to the Palomino Islets, where regulated 15–20 minute swims put you face-to-face with sea lions. Expect cold Pacific water, expert guides, wetsuit availability and onboard photos and snacks.
More ways to explore the area's outdoor wonders
The yacht slips past a working harbor into cold Pacific swell, and within minutes the shoreline of Callao shrinks into a ribbon of warehouses and watchtowers. Offshore, jagged islets—Palomino, El Frontón, San Lorenzo—rise raw and wind-sculpted; the Bertram moves into the shallows and the ocean’s life stakes its claim: barking sea lions, black-backed seabirds and the occasional flash of penguin.

Wildlife
History
The Callao archipelago sits near Peru’s oldest port; islands once factored into guano and fishing economies and are now managed for conservation under SERNANP.
Conservation
SERNANP regulates swim time and entry; visitors should avoid touching wildlife, pack out waste, and use reef-safe products to reduce impact.
Reserve your spot on the Palomino Islands Yacht Tour for Swimming with Sea Lions today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Respect the 15–20 minute swim window
SERNANP and guides enforce short, supervised swims to minimize stress on the sea lions—plan for a quick, controlled water experience.
Bring reef-safe sunscreen and a wind shell
The sun reflects strongly off the water and the ocean breeze cuts through layers; use reef-safe SPF and a light jacket for comfort.
Wear non-slip water shoes
Boarding and exiting the yacht and scrambling on rocky landing areas can be slippery—water shoes improve traction and protect your feet.
Don’t touch or chase wildlife
Sea lions can be curious but are wild—maintain distance, follow guide directions, and avoid physical contact for safety.
Swimsuit and quick-dry towel
You’ll swim briefly with sea lions and need a towel for the return to the yacht.
