The Palomino Islands form a small volcanic archipelago located approximately ten kilometers from the port of Callao, off the coast of Lima. Sheer cliffs, barren rock, cold Pacific waters: this chain of rocky outcrops concentrates one of the largest sea lion colonies on the Peruvian coast and offers one of the most accessible half-day excursions from the capital.

Why visit the Palomino Islands

The archipelago's primary appeal lies in its wildlife density. A colony estimated between 7,000 and 8,000 sea lions permanently occupy the rocks of the main island; adult males can weigh up to 400 kg. Operators permit supervised swimming in proximity to the colony, in waters that remain cool year-round due to the Humboldt Current.

Beyond the sea lions, the cliffs serve as nesting grounds for pelicans, cormorants, gulls, and various Pacific boobies. The fertile waters attract dolphins, Humboldt penguins, and occasionally during austral winter, passing whales. The ensemble was integrated in 2019 into the National System of Islands, Islets and Guano Points, a reserve status that regulates approach and landing.

History of the archipelago

Each island in the group bears a particular human trace, even though Palomino itself has remained largely uninhabited.

San Lorenzo, the largest, served as a cemetery for pre-Columbian peoples, then as a stone quarry during the colonial period: its blocks supplied the construction of Callao's prison and the Real Felipe fortress. It was subsequently used as a Peruvian military base.

El Frontón houses the ruins of a prison opened in 1917, intended for inmates considered the most dangerous. The island is associated with the 1986 hostage-taking led by Shining Path, a violently suppressed episode that remains a sensitive point in recent Peruvian history.

Camotal, nicknamed "Peru's Atlantis," appears only in summer at low tide. The islet was partially submerged following the 1746 earthquake that killed approximately 800 people in Callao, followed by a devastating tsunami.

Local accounts of pirates and smugglers using these rocks as hideouts circulate, but rest on fragmentary sources rather than documented evidence.

What to see and do on site

Swimming with sea lions

Operators typically provide a wetsuit, essential as water temperature rarely exceeds 18-20 °C in summer. Swimming takes place at a respectful distance from the colony: young sea lions, curious by nature, approach swimmers of their own accord. Touching the animals is prohibited.

Bird watching

The cliffs offer close-range observation of seabird colonies. A pair of binoculars and a camera with telephoto lens are useful; the boat does not land, observation takes place from the deck.

Tour of neighboring islands

Combined outings of 3 to 4 hours include a passage past San Lorenzo, El Frontón, and Cavinzas, nicknamed "the island of skulls" for its sea caves. Landing is rarely authorized: the visit remains maritime.

Practical information

• Excursion duration: 3 to 4 hours round trip from Callao, including approximately 1.5 to 2 hours of cumulative navigation.
• Price: moderate, generally higher for outings that include swimming with wetsuit provided.
• Equipment to bring: windbreaker, sun protection, non-slip shoes, swimsuit and towel if swimming, seasickness medication in case of rough seas.
• Supervision: guide mandatory, strict conservation guidelines (do not feed or touch wildlife, leave no litter, limit noise).
• Audience: suitable for families, but the sea can be rough and cold water deters some swimmers.

When to visit

The archipelago can be visited year-round, but Lima's dry and sunny season, from December to April, offers the best conditions for navigation and swimming. It's also the only period when Camotal reappears at low tide. From June to October, Lima's coast is covered by garúa, a persistent fog that reduces visibility, but cetacean passages are more frequent. The sea is calmer in the morning; most departures leave in early or mid-morning.

How to get there

All excursions depart from Callao's fishing port or La Punta marina, accessible from central Lima by taxi or ride-share in 30 to 45 minutes depending on traffic. No direct public transport serves the embarkation dock. Prior booking with an accredited agency is essential: departures are conditional on weather and may be cancelled in case of rough seas.

To combine in the region

The Palomino Islands excursion naturally extends to a visit of Lima's historic center and the neighborhoods of Miraflores and Barranco. For travelers continuing south to the Andes, the logical next step is via Arequipa and the Salinas and Aguada Blanca reserve, or via the Pampa Cañahuas National Reserve on the route to Colca. The Sacred Valley, with the Ollantaytambo ruins, rounds out a classic coast-to-Andes itinerary.
