Sea lions right up close, in cold Pacific water. This Callao Palomino Island tour turns a normal boat ride into a hands-on wildlife moment, with neoprene suits and a guide steering you through the colony while you also spot Humboldt penguins and lots of seabirds on the way. I like how it feels well organized for something that’s genuinely wild, and I like the wildlife focus beyond just the swim. One possible drawback: water can be very cold, and the time in the water can feel short depending on conditions and how the group manages it.

I also like the way the crew builds in time to enjoy the scenery—starting with the sail past San Lorenzo Island and the underwater pass through El Camotal—so you’re not staring at a sea-sickness horizon for the whole trip. If you’re prone to motion sickness, take that seriously before you go.

Key things to know before you go

• Palomino Island swim stop centers the day on a big sea lion colony, with neoprene suits and life vests provided
• Bird and penguin spotting happens on the sail over, so you get wildlife even if you skip swimming
• El Camotal underwater route and the pass by San Lorenzo Island make the boat portion feel more than transit
• Short, clear snack timing: water and juice plus a light snack help you recover after the swim
• Photos are built in on some departures, and at least one guide has shared GoPro files right after

Meeting at El Mirador and the sail through El Camotal

The day starts at El Mirador, where you meet the crew and get geared up before heading out. It’s a straightforward setup, but it’s still a real timing game: get there early so you’re not rushed when it’s time to put on your suit.

Then you’re off by boat, moving through the Callao area while the route includes a pass through something they call El Camotal (an underwater stretch), plus open sea and a view-by of San Lorenzo Island. Practically, this matters because it breaks up the trip. You’re not just sitting and waiting for the swim. You’re watching, listening, and getting your bearings for what comes next.

Also, note that a ride from Miraflores to Callao isn’t spelled out for you here. If you’re staying in Miraflores, ask about the safety transfer option ahead of time. That one small question can save you a stressful scramble on departure day.

Palomino Island swim: neoprene suits, life vests, and sea lion etiquette

Palomino Island is the main event, reached around 11:30 AM. This is where you go to a large colony of sea lions—so large that you can quickly lose the feeling that you’re visiting a zoo. You’re in their space, and they’re curious about your presence.

You’ll swim wearing a neoprene suit and with a life vest. That gear is the difference between feeling brave and feeling miserable. Multiple people specifically called out how cold the water is, and how the wet suits help. Even with the suit, plan for chilly water and a “shock” moment when you first get in.

What it feels like in the water

Expect playful, inquisitive animals that often approach you at close range. Several guides and passengers highlighted how friendly and curious the sea lions can be, even swapping the usual wild-animal distance for a very up-close experience. That’s the appeal. You’re not watching from a boat. You’re sharing a few moments of ocean with them.

Etiquette matters more than you’d think

You’re given instructions for what to do and what not to do, and you’ll want to listen closely. In one account, the guide was in the water helping with photos and keeping everyone safe, which tells you the operator treats this as more than a quick splash.

One caution: you’re not guaranteed a touch. Even though the animals may be very curious, the interaction can still depend on the water, the group, and where the colony chooses to swim that day. If you’re going in expecting guaranteed contact, you’ll be disappointed. If you’re going in expecting a close swim-with-animal experience, you’ll likely be thrilled.

Guides can make or break the vibe

The strongest praise in the feedback isn’t just about the animals. It’s about the guides’ attention. People named guides like Ricardo and Fernando, Alex, Julio, and Rodrigo—and consistently mentioned clear safety instructions, helpful guidance, and real enthusiasm.

One standout detail: a guide used a GoPro to make videos and take pictures with customers, then sent the files afterward. If you don’t have waterproof equipment, that kind of service can add real value. If you do bring a device, you’ll want a waterproof sleeve.

Wildlife on the way: penguins, pelicans, and seabird spotting

This isn’t a one-note tour. On the sail out, the guide points out wildlife, especially seabirds. You can see Humboldt penguins and a lot of other birds during the trip, and it’s not just a random sighting—it’s guided so you actually know what you’re looking at.

A few species were specifically mentioned in the feedback, including pelicans and other seabirds like cormorants and terns. Even if you’re not a hardcore birder, the guidance makes the boat portion more rewarding. It turns the trip into a moving wildlife viewpoint instead of a long wait.

For bird lovers, this matters because it can feel like the day is about more than the swim. You can still get a strong wildlife payoff even if you don’t go in (some people chose not to swim and still enjoyed the birding and scenery).

Returning through cliffs and islets, plus the snack stop

The schedule is built to keep things tight and efficient. You start heading back around 12:35 PM and should reach the pier in Callao by about 1:00 PM.

The return route includes impressively shaped cliffs and islets, which is a nice bonus if you like seeing the coast rather than just the open water. You also get a snack and drink on board, which helps because you’ll likely be cold and a bit tired after the swim portion.

One small reality check: changing can be awkward. Some feedback noted bathrooms at the dock for changing back, while others mentioned you can also change on the boat with limited privacy. Bring a plan for quick changing and keep your personal items stored safely.

Cold water, sea-sickness risk, and boat comfort you should expect

Let’s talk comfort, because this is where expectations can go sideways.

Water temperature

Even with neoprene suits, the cold is real. People explicitly said the water was very cold and that the smell can be strong when you’re near the colony. That’s normal. It’s also part of the authenticity. You’re swimming with wild animals, not in a resort lagoon.

Motion sickness

If you’re sensitive to waves, take it seriously. At least one person recommended taking motion-sickness tablets ahead of time after experiencing sea sickness in the group. The boat ride does include waves, and you can’t count on a perfectly smooth ocean.

Boat size and movement

One review noted the boat felt small and that there wasn’t much space to move around. So, if you need to stretch, pick a spot where you can handle sitting for a bit without feeling trapped.

Price and value: what $76 really buys you

At $76 per person for about 150 minutes, you’re paying for three things: a guided wildlife boat trip, the specialized swim setup, and the logistics that get you to Palomino Island.

Here’s what’s included:

• Tour around the islands of Callao
• English and Spanish speaking guide
• Neoprene suit and life vest
• Swimming with sea lions
• Snacks and water or juice
• Insurance against personal accidents on board

What’s not included:

• Natural Reserve Protection and conservation fee
• Binoculars
• Outerwear/raincoats
• Sunscreen, masks, fins
• Towel

Is it worth it?

For me, the value comes from the mix: the swim isn’t just the headline, it’s supported by safety gear, a guide in the water, and a timed wildlife route that includes penguins and birds. If you’re only after a boat ride, it’s probably pricey. If you want a real wildlife interaction that’s structured and safe enough for a first-timer, the price can feel fair.

One more value point: some departures include photo/video help, which reduces the need to buy or rent waterproof gear.

What to bring (and what to skip)

Here’s your simple packing list, based on what the operator expects:

• Towel (not provided)
• Change of clothes
• Sunscreen

Also useful based on how people described the day:

• A waterproof way to protect your phone or camera if you want it in the water
• Motion-sickness medicine if you’re prone
• Something you can manage quickly for changing, since privacy may be limited depending on how the crew handles suit changes

What not to bring:

• Pets
• Drones

Who this tour suits best in Lima’s Callao region

This is best for:

• People who love wildlife and want close-range interaction (with guidance and gear)
• Bird lovers who want Humboldt penguins and seabird spotting on the boat ride
• First-time swimmers who want a guided, controlled setup with neoprene suits

You should think twice if:

• You have heart problems, you’re dealing with a cold, or you have pre-existing medical conditions
• You’re uncomfortable with cold water and don’t want to be cold before and after the swim

If you’re traveling as a couple or solo, this can be a great way to do one intense wildlife moment without spending a whole day on a long expedition. It’s also a strong option for limited time in Lima.

Should you book Callao sea lions at Palomino Island?

Book it if you want the kind of experience that feels rare and real: sea lions close enough that you remember the sound, the curiosity, and the ocean setting. The guided wildlife element, including penguins and lots of birds, makes it more complete than a pure swim-and-leave situation.

Skip it if cold water and limited comfort are dealbreakers, or if you have medical concerns that match the tour’s non-suitable list. And if you’re expecting a guaranteed touch, adjust your mindset: the plan is a close swim alongside the colony, not a controlled interaction on demand.

If you do book, I’d plan around three things: get to El Mirador early, bring a way to handle cold and changing, and consider motion-sickness support if waves normally get to you.
