      Highly Recommend!
      Angel was an amazing tour guide. He was very knowledgeable of not only Cueva Del Indio, but of the Island’s history and its landmarks on the drive there. It was a small group of 4 of us and he was very attentive and made sure we all felt safe and comfortable! He also took us to a local restaurant in Arecibo after the excursion and it was amazing. Highly recommend Angel and this excursion to everyone. 10/10

      THE HIGHLIGHT OF OUR TRIP
      The tour guide Angel was truly an Angel! He guided us through the whole tour and ensured that we had a blast and were safe! I can be a little unsteady on my feet so I was nervous but he completely made sure I didn’t fall. We learned so much about Puerto Rican history, even things that weren’t right there at the tour. He was super funny and made us feel very welcome! He answered all of my questions about Puerto Rico and encouraged us like a cheerleader. The scenery will speak for itself and the drone photos made everything sweeter!

      Best way to experience the whole island on a budget
      We've been to Puerto Rico many times and learned even more during this trip! Our guides were amazing and took us to see both popular tourist attractions and hidden gems. When they say you go around the island, they mean you go all around the island in one day! We got to stop for some fruit- the best pineapple and mango we've ever had. There is a set itinerary, but if you want to stop and take pics of something else along the way, they're also flexible. Wear comfy shoes because you'll be hopping on and off the van throughout the day, and exploring some great spots during the trip.

      Best Tour Ever!!!
      This was our best tour during our trip to PR. The views were to die for and truly one of a kind. Our tour guide Angel was spectacular! He was very personable, kept you laughing, incredibly knowledgeable, and ensured our safety was in tact! Going through the hole to get into the cave could be quite scary, but Angel made sure to have each person comfortable and safe in the upmost respectful way! This trip was for my 21st birthday and was truly magical! Thank you Angel!!

      An Amazing Experience
      We went on a girls trip and Angel was absolutely amazing! Best tour guide ever! Angel provided lots of information and took us to the places along the way. He allowed us time to take pictures and didn’t rush us. He was very funny, down to earth, and personable. The views from in the cave and from above were absolutely breathtaking. He showed us where parts of Pirates of the Caribbean were filmed and allowed us to take pictures at those spots. He also takes pictures of everyone with his drone which is cool as he gets a better view and the pictures came out amazing!! It was quite the exercise during the climb in and out of the cave but Angel is very good about making sure everyone feels safe. It was definitely a great way to start our trip. I highly recommend this excursion during your trip.

      Some of the best views in PR!
      This was an amazing experience. Angel was our guide and he was very knowledgeable of the area. This trip also has some of the best views I’ve seen in PR! I would 10/10 recommend this experience. I would recommend wearing some good hiking shoes as there are some sharp, steep rocks.

      AMAZING!!
      The perfect amount of adventure and culture. This was one of the only excursions we planned for our visit in Puerto Rico, and it was everything we hoped for! Our guide Angel could not have been better, showing us all the best things that the cliffs and caves have to offer. Also the ride there was perfect, with quick stops at unique areas. Angel kept us well hydrated, fed, and comfortable. I will be highly recommending this for anyone visiting PR. Thank you Angel!

      Best Way to See the Island
      I cannot say enough about how great Angel and Mariela were. They managed to pack in a trip around the island in one day where we saw and learned a lot about Puerto Rico. Angel has a great sense of humor as well as abundant knowledge of his beautiful island home. Both were friendly, helpful, generous and kind. Even though it was a long day, it was well worth it. The multiple stops made it a great way to get a lot of pictures and hear about Puerto Rico’s history. From Old San Juan to Ponce with numerous coastal towns in between, you won’t find any other tour with all they offer. They even stopped for an impromptu coffee break when I asked! We stopped for a great lunch and snack, and they made us feel welcome, like part of their family! Thank you for the memories! I highly recommend this for anyone who wants a fun day of learning about this great island with great people!

      Worth every penny !
      The tour was excellent. We were a very small Group, only three people plus the guide, Mariela, who really enjoys explaining about her land. We went around all the island stopping in many interesting towns. Mariela is very knowledgeable and answered all our questions and more !!! We spend a great day together!! Worth taking this tour, definitely in your list.

      You must do this tour!
      This tour was incredible! Our tour guide, Angel, is the nicest guy, very informative, and took lots of pictures of us with his drone! He took us to a beach with magnetic sand, gave us a first-hand account of Hurricane Maria, and led us on an amazing cave tour where we saw petroglyphs and unbelievable views. Even though the climbing required more agility than I was prepared for, he helped us through and I never felt in danger. This cave tour is a must-do!!!

    This tour turned out to be great, despite the fact that the Arecibo Observatory was closed for safety inspection after the earthquake. Everyone who booked this tour cancelled except us. Angel Diaz gave my husband and I the tour anyway - even though this was probably not profitable for him. He gave us lots of information about the history and political situation in Puerto Rico. Highly recommend this enthusiastic and helpful guide!
