• 5Yamile made this even more amazing

  Yamile was absolutely amazing!! Great conversation and so knowledgeable about the island!! She was super sweet and made us feel like one big family all day!! She safely navigated us through the waters and climbing up rocks, it was a good amount of physical exertion but it flew by with how much fun we were having with her!! If you’re in Puerto Rico you HAVE to book this. The caves and all the nature surrounding it was absolutely breathtaking! 100/10 recommend!!!

  I went with my friend, and the pick-up was right on time. The drive to the caves was fun, and Yamille shared very interesting insights about Puerto Rico along the way. When we arrived at Cuevas Arenales, she explained the activity very well and made sure we understood everything. My friend was afraid of rivers because of a past experience, but Yamille made her feel comfortable and supported her throughout the experience. With Yamille’s help, my friend was able to overcome her fear and complete the tour. The experience at Cueva Arenales is truly unique. You get to witness a place that has existed for centuries and appreciate its natural beauty. I highly recommend this activity!

• 5GREAT for solo travelers!!! You will have a BLAST!! GRACIAS PRIMA!!

  YAMILE IS AMAZING!!! So, I went to PR for a week and went completely alone and without any plans. I had no idea what I would do so I had an open mind to whatever happened! I came across this and saw the plenty of reviews so I decided to give it a shot. Signed up although I did so the night before the event, I was worried I wouldn't hear much or get information quickly but minutes after booking she was reaching out to me with a very welcome message. We even had a lengthy phone call where she replied to all my questions and gave me an extreme thorough explanation of how everything would go. Being a solo traveler I was very much put at ease and went in ready for the next morning. She showed up promptly to pick me up and we waited for the others in the tour. It was myself and another family so it wasn't as big of a group but it made for a more intimate experience where she gave us all great attention. The drive isn't crazy long and she makes it engaging all throughout as well as getting to know everyone in the group. She has a thing where she calls you her family, funny thing is that she does take care of you like family. She's funny, VERY sweet and kind while having a great level of energy. you can ABSOLUTELY tell that she actually is passionate about this and it isn't just another job. I do not regret this trip WHATSOEVER, in fact, I would love to bring more people to experience what I did. After the trip she takes us all to a local restaurant where you know that it's local as everyone who is there you can tell is puerto rican and not just a bunch of tourists. She also took photos of everyone all thorough in addition to videos too. At the end she just sends it through airdrop so you also leave with several HUNDRED pics and videos too. OVERALL I give her a full 5 start experience and am so thankful that she made this trip even better than i could have EVER IMAGINED!!!

• 5Highlight of my trip!

  Yamile was the best tour guide ever 💕 her love of Puerto Rico showed with how much she taught us about the local habitat for every place we saw throughout the tour. She lead us through the forest and river with so much passion, even making sure to leave enough time for good picture opportunities. Not only did we leave this tour with an amazing experience, but we also got to learn while doing so. If given the opportunity I'd definitely book with her again!

• 5Absolutely Unforgettable Adventure!

  Yamile have us one of the best experiences of our trip to Puerto Rico! From start to finish, the entire day was an incredible adventure filled with breathtaking scenery, exciting hiking, river trekking, swimming through crystal-clear waters, and exploring spectacular caves and limestone canyons. Every part of the journey felt like discovering a hidden paradise! Our guide was fantastic—knowledgeable, professional, friendly, and genuinely passionate about sharing the beauty and history of the island. The small-group experience made the trip feel much more personal, safe, and enjoyable, and we never felt rushed. The scenery was absolutely stunning, from the lush tropical forest and waterfalls to the beautiful blue-green water and incredible rock formations. We also loved getting to enjoy authentic Puerto Rican food and ending the day at the peaceful hidden natural spring—it was the perfect finishing touch to an already amazing adventure. If you’re looking for an exciting, immersive, and truly unforgettable day in Puerto Rico, do not hesitate to book this tour. Worth every penny and then some! We made incredible memories and would absolutely do it again. Highly, highly recommended! ⭐⭐⭐⭐⭐
