The Palomino Islands lie off the coast near the port of Callao, a short boat ride from the Lima mainland, and they are home to a large colony of South American sea lions. Seabirds crowd the rocks, and on a good day you may also see Humboldt penguins and other wildlife that thrives in the cold, rich waters of the Humboldt Current. The headline experience is a swim with the sea lions, in which you slip into the water in a wetsuit and life jacket while the animals swim and play around the boat. For those who prefer to stay dry, the boat itself gets close enough to watch the colony from a safe distance. The product on offer is the Palomino Islands Speedboat Tour and Swim with Sea Lions, which departs from the Callao area and typically lasts a few hours in total. It is the easiest wildlife encounter you can reach from central Lima, and it is much shorter than the Paracas day trip, which makes it a good alternative if you want sea lions without a very long day.
Why it matters
Wildlife encounters near a capital city are rare, and this one is relatively intimate. Seeing a sea lion glide past underwater is a vivid memory, and the colony is a reminder that the cold Pacific here is one of the richest marine environments on earth. For many visitors it is also a welcome contrast with the cultural sights that dominate a Lima itinerary.
How to see it
The tour meets at a marina or pier in Callao, and many operators arrange transfers from Miraflores and nearby districts, so confirm your pickup. The speedboat takes around half an hour to reach the islands, where the guides brief the group on safe behaviour before anyone enters the water. Wetsuits, life jackets and masks are usually supplied, but check what is included. Bring a towel, a change of clothes, sunscreen and a light jacket for the boat, because the wind and spray are cold even when the sun is out.
Good to know
The water is cold, so the wetsuit is essential, and the sea can be rough, which means departures can be delayed or cancelled when conditions are poor. The wildlife is unpredictable, so no operator can guarantee close encounters. Rules about minimum age and swimming ability vary by operator, so ask in advance. Never touch or chase the animals, and follow the guide's instructions. Summer, from December to March, is usually the most comfortable season for swimming, and mornings tend to be calmer than afternoons. Check the tour details for your date.
Making the most of it
Listen carefully to the guide's briefing, because the animals are wild and the rules protect both you and them. Enter the water calmly, keep a respectful distance and let the sea lions come to you, as they are often curious and will circle if you stay still.
A waterproof phone pouch or a small action camera adds to the memory, though salt water and cold fingers make photography harder than you expect. Afterwards, a hot drink and a plate of fresh ceviche at one of the Callao or Chorrillos seafront restaurants is a fine way to warm up and finish the outing.

Good questions
Can anyone swim with the sea lions?+
Rules vary by operator. Most require basic swimming ability, and minimum ages differ, so ask when you book.
Is the swim cold?+
Yes, the water is cold all year, which is why wetsuits are usually supplied. Bring a towel and a warm layer for the boat.
Will I definitely see sea lions?+
The colony is large and sightings are very likely, but wildlife cannot be guaranteed. Penguins and other seabirds are a bonus.
What if the sea is rough?+
Trips can be delayed or cancelled in poor conditions. Ask the operator about its policy before you book.
How does this compare with Paracas?+
Palomino is much shorter and closer, so it suits a half day. Paracas and the Ballestas Islands offer more variety but take a full day.
