Know More about this tour

After pickup from your hotel head to your first stop: Rio Camuy Cave Park, where youll enjoy a guided tour of this marvel of nature. In the park, 3 crater-like sinkholes and 1 cave are open to the public.Youll encounter sinkholes and cathedral-like caverns, eons-old stalactites and stalagmites, and a mysterious underground river. There are a few cave systems in the world that are as massive or dramatic as the Rio Camuy Cave Park, and no other has a thundering tropical river traversing countless miles of underground channels.

After exploring the cave system, your tour continues to the Arecibo Observatory. Nestled in the mountains of northern Puerto Rico, the observatory is home to the world's largest radar/radio telescope.Scientists from around the world make use of the giant 1,000 foot-diameter dish to listen to the universe. Youll have views of the huge telescope from an observation platform, where its austere metallic symmetry shimmers in dramatic contrast to the dense, green, tropical landscape.

You'll spend about 1 hour walking inside, highlights include:
  • Going through the dense tropical vegetation down the mouth of Clara cave.
  • Stop at the 650 ft. wide Tres Pueblos sinkhole, where special platforms allow visitors to view the river passing 400 feet below from one cave to another.
  • Stop by the Espiral Sinkhole, where visitors can actually descend some 205 steps to reach its striking entrance.

After the Camuy Caves, we'll go to one of Puerto Rico's most recognizable landmarks, the Arecibo Ionospheric Observatory. Built in 1963, it is a very important part of investigations of inter-spatial communications in the US. The radio telescope's dish measures an amazing 20 acres, the largest in the world.Once we get to the observatory, we'll walk up a fairly steep hill to get to the observatory itself. The walkway is a combination of steps and an inclined sidewalk, but the observatory offers a free ride to the entrance for elderly & handicapped guests.

You'll have an opportunity to see more than 25 various exhibits and see the dish! In addition, you will get to:
  • Learn about the Earth and our solar system.
  • Learn about our neighboring stars and galaxies
  • Learn about technology used in studying these natural sciences.
  • See meteors on display
  • Watch a short movie called "A Day at the Telescope"

  • This was a great tour! Our guide, Omar from Bespoke Lifestyle Management local tour operator was fully knowledgeable not only about the specific destinations but about all of Puerto Rico. It was around a two hour drive from San Juan to Rio Camuy Caves and he kept us informed the entire time about local towns, their industries and history. He also pointed out the flora and fauna we saw along the way. He left us so we could join the tour group for the cave, then re-met with us to continue on to Arecibo Observatory - Very Fascinating!! Highly recommend this tour and tour guide.

  • Really enjoyed this trip. The guide was wonderful. She was enthusiastic and knowledgeable. It was nice to get out of the city and see some of the countryside. I was really interested to see the telescope and it is amazing. I am a scientist and found this site was informative and entertaining. The caves were impressive, lots of bat pooh. Joking aside, plenty of time to see the caves , the guide was excellent. Not strenuous at all. We would recommend this tour

  • The local company that took us was Bespoke Life Style Management. Estrella picked us up at the hotel. She was great. She was friendly , knowledgeable and easily approachable. She started giving us information as we drove to the caves. The caves were very interesting. They have their own tour guide. You need to wear footwear with good traction. The trails are cement and rock. A good part of the trial is wet and the rock parts are a little slippery but manageable. From there we drove to the observatory. Here too, Estrella gave us information along the way. There wasn't as much to see at the observatory as I thought. You don't spend that much time there. But, the cave more than make up for the fun you don't get at the observatory.

  • Our Driver was excellent and the Camuy Caves part of the tour was great, but unfortunately we were unable to see the Observatory because it was close. The tour company was very accommodating in
    giving us options for this. Highly recommend .

  • Wonderful tour! Our guide Jesus was terrific and we enjoyed his humor and stories throughout the day. The caves are beautful and a very easy walk. The visit to Arecibo was fascinating. As a space buff, seeing the radio telescope and hearing the science being done there was a wonderful experience for me. Well worth a visit!
