Expect a full-day boat trip from Lima’s port out to the Palomino Islands (part of the Guanera Islands reserve). The ride takes about two hours each way on a speedboat that can get choppy. Once there you’ll see huge colonies of sea lions hauled out on the rocks, seabirds everywhere, and then you jump in the water with a wetsuit and snorkel gear to swim near them. The sea lions are wild and curious; they often zoom past you underwater or play around the group. It’s impressive but not a petting zoo—keep your distance and let them approach. The water is cold (around 60°F/15°C) even with a 5mm wetsuit, and visibility is usually decent but not Caribbean-clear.
Best time is December through March when the water is slightly warmer and the Humboldt current is calmer. The rest of the year it’s still doable but rougher and colder. Expect to pay around $80–$130 per person for a standard tour that includes transport, wetsuit, snacks, and a guide. Private or smaller yacht options push toward the higher end.
Pick a morning departure that actually stops for a proper swim at Palomino rather than just a quick look-and-go. Skip the big party boats that blast music the whole way; they’re stressful for the animals and less enjoyable. Bring your own towel, motion-sickness meds if you need them, and a dry bag for your phone.
