Welcome to Mar Adentro Excursiones

Mar Adentro Excursions, is a company dedicated to marine adventure. Our desires are to show the nature specifically in the islands of Callao especially the great colony of sea lions, penguins and guano birds. For which it has modern speed boats where you will make excursions and other nautical activities.


The ideal of Mar In Excursions, is to generate interest for the sea, through excursions that integrate you with the marine environment beyond the line of the beach. This contributes to their protection, avoiding the deterioration of coastal marine areas, which day by day degrade, not by negative feelings towards the sea, but by ignorance and the consequent lack of interest towards the sea.

“Fantastic experience and well worth the $. The sea lions will kiss your feet. Relax let go of your fears and let nature do the rest.”

“This is one of the most unique experiences my husband and I have ever done. It was absolutely incredible to see all of the sea lions and how inquisitive they are of us. The staff was amazing and fun! Not only did they take us to see the sea lions, but they gave us opportunities to take great pictures! You have to do this!”

“It was really a fun experience. I personally did not swim with the sea lion because I worry that the water was too cold for me. But some other young people went down and really enjoyed the experience. There were thousands of sea lions on the island and in the water, so it was a Magnificent sight even by seeing them. Our guide Julio was very nice. The sea was a little rough and a choppy when we were passing between the islands, but it was OK. I highly recommend this experience”

“So much fun. I took our 12 year old son and he loved it, not scary at all. After a short boat ride past a couple coastal islands, you arrive at the one with a gazillion sea lions. immediately they slide into the water. You go in as a group wearing life preservers so you're head is above water the whole time. The sea lions are both wary and curious, so they're close but not touching...unless they nibble your toes a bit.”

“Exceptional experience, unlike any we’ve experienced before. Swimming with hundreds of sea lions in their natural habitat! I still can’t believe it!! The team is also great - organized, patient, funny, and considerate. Many thanks for the great time!”

“Incredible. I cannot reccomend this enough. Our guide was kind and funny. The scenery is like something out of NatGeo. The experience itself is truly wild. You may be thinking " Oh swimming with a few Sea Lions, thats nice." IT IS HUNDREDS. The sea boils with them. The only thing that could make it better is having David Attenborough himself as you guide.”

“Amazing experience!! Highly recommended. Word to the wise: if you've ever gotten motion sickness ever in your life, bring anti-nausea medication. Clothing-wise: be sure to have your swimsuit on when you get onto the boat, under your clothes. Also be aware that there's no room to change out of your swimsuit on the boat. Ladies, wear a dress or something else that's easy to slip on and off and that you don't mind getting damp.”


Roynel Watson

“Very clean and neat. And very helpfully staff bellboy were helpful. Good location”


Laura Kumpuniemi

“Swimming with sea lions was great! The staff was friendly and the animals amazing. If you have any bad experiences with motion sickness, prepare yourself with medication for that because the sea might get rough. Also the smell of the sea lions isn't very pleasant, so also expect that. Otherwise, I totally recommend this experience!”

“The boat tour and sea lions were even better than I expected! It was different than anything else I experienced in Lima. The tour was well operated and the guide was very friendly and professional.”


Caitlin Hall

Aylmer, Ontario, Canada

“Our tour and swim with the sea lions was great! There were so many sea lions and they were very curious about us. Some of them swam close enough to touch us. Our guide was Julio and he was amazing. He was very knowledgeable about the area and the animals and birds . This is a must do if you are in Lima.”

“Una experiencia genial, les recomiendo vivirla!!! eine tolle Erfahrung, empfehle ich es zu erleben!!!”


Raeesa Ebrahim

Dallas, Texas, United States

“This was an incredible experience, and I would highly recommend it. We were a bit late because of Lima traffic, but the tour waited for us. There was a quick safety briefing, and then about 20 people got into the boat. The tour itself was very educational, and the guide and captain both spoke English and Spanish. The water did get a bit rough at times but very few people were seasick. The boat got very close to the islands so we were able to spot many of the species that were discussed beforehand. The company provided wetsuits which were necessary for the cold water, guidance on how to behave around the sea lions, and snacks for the return trip. This was a highlight of our trip to Lima, and we'd definitely do this again.”


Mariel Beausejour

“I have traveled my whole life, to 6 continents, 17 countries, and over 5 years spent outside of the US and Canada. This was the best travel experience of my life. it was AMAZING. I couldn't BELIEVE my eyes and my ears. The Sea Lions swam up to us, and under us, and kissed our feet. They are friendly and curious. The water was a bit cold, but who cares?!”


Miguel Rodriguez

“Simply amazing. You can get the nearest you can to the sea lions with this experience. You will also get thorough explanations about the islands in Callao. Make sure to bring a towel with you and a camera you can swim with /// Simplemente asombroso. Puedes acercaste lo más que puedas a los leones marinos con esta experiencia.

Theresa Csuk

“Great experience!!!! We loved it!!!! Everything was perfectly organized. We got picked up at the meeting point on time. While waiting for the boat to leave, Coffee was offered. We saw a lot of wild birds, crabs AND the sea lions. They gave us wetsuits and life jackets to swim with them. There were so many sea lions, it was amazing!! I never felt unsave, it was such a nice experience to see these animals close and swim with them. Our guide Julio was very friendly and he explained us a lot of things about the different animals. In the water he took fotos. Back on the boat we got Snacks and Drinks. :D I would really recommend this experience!! It made our stay in Lima unforgettable!!”

“Swimming with seals was an extraordinary experience. Eduardo & Fernando were really great. I took advantage of their additional pick up service which was punctual and comfortable. If you can handle wetsuits and the water you should not miss this opportunity.”
