What To Expect
Vega Baja
Get ready to be amazed, get wet and enjoy some adrenaline almost as soon as this adventure starts. After a few minutes of walking downhill, we will encounter the river where it forms beautiful greenish blue pools and start swimming through a breathtaking small canyon carved by the passing of the river for thousands of years. The rock formations are amazing, unique looking and there will lazily float through the canyon admiring this nature’s gift and later do some river trekking. The more adventurous will have a chance of some optional cliff jumping in areas ranging to 8 to 20 feet and rock boulder to access the upper part of the canyon. Afterwards we will hike through an off the beaten path trail to access some incredible caves where we will swim through them surrounded by stunning flowstone rock formations, bats and a beautiful waterfall. Good physical condition and basic swimming skills are required to complete these activities.

Amazing experience

5.00This was such an unforgettable and fun experience! The water was definitely cold (as expected in the river and caves), but that actually made it even more exciting and refreshing. We swam through the river wearing life jackets, walked through the water, explored multiple caves, and even jumped into the water at certain spots. There were waterfalls inside the caves, which was absolutely beautiful and unique. Our guide, Yamile, was amazing. She was very friendly, patient, and professional, and made everyone feel safe and comfortable the entire time. She guided us carefully through the water, explained everything clearly, and kept the atmosphere fun and relaxed. You can really tell she cares about her guests and loves what she does. This tour was adventurous, well organized, and suitable even if you’re not an experienced swimmer because of the life jackets and guidance. I highly recommend this tour to anyone visiting Puerto Rico — it’s a perfect mix of adventure, nature, and fun. Thank you, Yamile, for such a great day!
Wonderful time!

5.00If you are looking for a water/hiking adventure to get you out of the San Juan metro area for the day look NO FURTHER. You found it!!! Yamile was the ultimate tour guide. She truly went above and beyond in her communication, time management, hospitality, and spirit! Some parts of the trail you do have to go slow and be careful, but Yamile gave very good directions and never made anyone feel rushed. Also the rocky trails are part of the fun!! Just make sure to wear water shoes with a good grip and be okay with some steep incline. In addition to the wonderful river caves we were taken to a local spot for lunch which was incredible like seriously top 5 meals of my life I will never forget you pork ribs❤️❤️ and, like the rest of the trip, Yamile has the coordination for ordering down to a T, which was very helpful for me considering I am terrible at Spanish. We also took a nature walk after eating and saw a beautiful crystal clear water hole. I also appreciate that the van has giant windows so you can appreciate the island's beauty, coming from someone who has never been here before! And the cherry on top was that she took many many photos and sent them to us FOR FREE!!! 10/10 I'd literally do this once a week if I could. Thank you again Yamile 🙏 🙏🙏
Absolutely unforgettable experience, Yamile is the best!

5.00This was honestly one of the highlights of our entire Puerto Rico trip, truly so, so good. Our guide Yamile was hands down the best, sweetest, and most caring guide we’ve ever had. We were staying in Brenas, which is outside of the official pickup area, but she still went out of her way to arrange a convenient pickup point along her route so we could join , which already meant a lot. What made it even more special is that we almost had to cancel because a last-minute meeting came up. The night before, Yamile actually called us and spoke with such warmth, enthusiasm, and sincerity that she convinced us not to miss it, and we are so grateful we listened. It truly felt like she genuinely cared about us having this experience. Her van was very clean and comfortable, and the drive included narrow, winding mountain roads, but she drove extremely carefully and confidently, which made us feel very safe. She also provided everything we needed: life jackets, water, and all the gear, so we could just relax and enjoy the day. Along the way, Yamile shared so much about the local history, culture, scenery, and tropical plants. It never felt scripted, it was engaging and you could tell she really loves what she does. The tour itself was incredible: waterfalls, hiking, climbing, caves, rainforest, canyon views, cliff jumping, and floating through the river. The part where you just drift in the water was especially refreshing and peaceful, it felt like a reset. Yamile also took tons of beautiful photos for us, with great angles and timing, so we could fully enjoy the experience without worrying about capturing everything ourselves. She then brought us to a very local, delicious lunch spot, not touristy at all , such a nice touch. From 7 a.m. to around 3 p.m., it felt like a full day of adventure with someone who truly cared about making it special. We honestly didn’t want it to end. We had done an El Yunque tour last year, and this experience was on a completely different level, more fun, more varied, and with a guide who was far more engaging, attentive, and thoughtful. Highly, highly recommend booking with Yamile. If you’re choosing between tours, choose hers. You won’t regret it.
A wonderful day of exploration on land and in cool water!

5.00This was an amazing day of adventure! Yamille was a fantastic guide- so knowledgeable about fauna & flora as we hiked, climbed and swam through caves. She went above and beyond to assist members of our group in traversing the sometimes difficult terrain, advising on foot and hand holds and sharing the history of the area. I would go on any tour led by her! ‘Yami’ further assisted and accommodated participants with suggestions regarding other activities and places to go in PR. Her kindness, experience and knowledge were appreciated by all in our tour!
The best way to see the caves

5.00My family had a great time on the tour with Yamile. It was nice to get away from San Juan and see other parts of the island. Swimming in the river was fabulous though as others have noted, you need to be somewhat physically fit maneuvering around and over rocks. Lunch was delicious and Yamile helped us with the ordering as our Spanish was a little rusty. After lunch we had a short hike to a spring which was really beautiful. Yamile was an awesome guide, don't hesitate to book this trip.
Great family experience

5.00Absolutely excellent!! Jamile was a wonderful guide; friendly, knowledgeable and helpful. Tour was excellent and our family’s favourite of our time in PR (2 adults, 12yr and 9yr) Reconsider if you have knee problems as it requires maneuvering uphill and over significant rocks but otherwise don’t hesitate to book this one! Communication beforehand was excellent and tour ran on time.
Yamile was awesome. Best...
