Don't Miss This One!
This was the highlight of our vacation! The natural waterslide, pools, and scenery...oh my! Brian, our tour guide's passion for giving tours, knowledge of the rainforest, and preservation of the flora and fauna was very evident. He was very encouraging and kept safety in the forefront at all times. You can't beat having a small group of 6 as it made for more intimate experience and worry-free transportation. Lunch at Luquillo was perfect and a great ending to an amazing day. I would do this again in a heartbeat! I do recommend that participants have good balance and leg strength to handle the more strenuous parts of the tour.

Wonderful
This was an incredible experience. Guides were knowledgeable, kind, patient, and took great photos! The hike wasn't too difficult and there's plenty of time to recover at the water before heading back. Apply sunscreen, but don't bring anything with you on the hike. It's easier if you have your hands free. Phones/Cameras are not necessary as the guides take plenty of photos - of the people on the hike, and of nature itself.

Well worth it! From...
Well worth it! From picking us up at our hotel, to the knowledge that Brandon our tour guide had, everything was great. We shopped at a local boutique and had wonderful Mofongo at Raíces.
The best part honestly was Brandon..he was funny, kind and made the day perfect!

Fantastic Experience!
This excursion was a fantastic experience! Great hiking, floating, and a beautiful location! The Able and his team were phenomenal: kind, helpful, funny, and knowledgeable. It’s not *just* a relaxing time on the river: be prepared to hike trails, walk through water anywhere from ankle to waist deep, enjoy a waterfall, and maybe even pretend you are Mario or Luigi! We would definitely do this adventure again!

Book it.
Very convenient, they pick you up and drive you back, take care of your ferry tickets. No need to call and wait for Uber for the same price, even higher. You’ll be in Flamenco beach from 11a-4p which I think is more than enough time to enjoy the place.

Highly recommend this fun...
Highly recommend this fun excursion. Got to see some amazing beaches with our knowledgeable guide, Rafael. He was very helpful in every way possible, friendly, fun and gave clear instructions. I couldn’t have asked for better. Bio Bay was amazing. They pair you with another amazing company. Very organized and a good time. Would do this again with them.

BOOK IT!! Highlight of my trip!!
Incredible experience!! The crew takes care of you completely, food, drinks, activities. They sometimes go to Culebrita island instead of Flamenco beach if the weather has caused a lot of seaweed so we ended up going to Culebrita and I am SO GLAD!!! It was Stunning!! I ended up getting a little sea sick on the way there (normal for me) and the crew was so sweet and helpful providing sea sickness bags, ice to put on my head, lots of water and checked in on me. I will definitely be back to book with them and try the snorkeling tour!

Nice and easy
This was a wonderful, low stress, and low-intensity half-day experience in El Yunque. I did not want to miss the opportunity to visit the rainforest and booked this at the very last minute as it was one of a few that offered transportation; I appreciate that Isaac and Fernando were able to pick me up at a nearby meeting spot. We got to spend just enough time at one of the rivers/watering holes and I enjoyed the lunch spot we stopped at. An overall engaging experience that capped off my trip nicely. Thank you!

Great for a solo snorkeling trip
I had a wonderful time. I did come prepared which helped. You should know how to swim for this tour or bring your own life jacket. But the staff is very friendly and accommodating. The boat was fun and the music play list was banging. I was able see a lot of fish at both locations and the sandwiches and drinks were good. I would highly recommend.
