The Arecibo Observatory And The Rio Camuy Caves In Puerto Rico

The Arecibo Obseratory

The Arecibo Observatory


The Arecibo Observatory is the world’s largest single aperture telescope ever constructed. Scientists who want to use the telescope must submit proposals and those are evaluated by an independent board.

Puerto Rico’s location near the equator allows the telescope to view all of the planets in the solar system. The telescope was opened in 1963. There have been many significant scientific discoveries made using this telescope. It has been used for military intelligence, too. The United States was able to locate Soviet radar installations by detecting their signals bouncing off the moon!

There's a chance you've seen the Arecibo radio telescope, even if you've never been to Puerto Rico before. In the climactic last scene in the James Bond movie Goldeneye, the showdown between 007 and the bad guy takes place right here.

The Rio Camuy Caves In Puerto Rico


The Rio Camuy Caves contain the third-largest underground river in the world. The river runs through a network of caves, canyons, and sinkholes that have been cut through the island’s limestone base over the course of millions of years. Known to the pre-Columbian Taino peoples, the caves came to the attention of speleologists in the 1950’s when they were led to the site by local boys who were familiar with some of the entrances to the system.

Apparently, these caves were a popular place for the boys to explore.

The caves were opened to the public in 1986. A trolley takes visitors to the entrance to the caves. A well constructed concrete path leads down to the caves. This path is very slippery, but there were guard rails to hold onto. It is a fascinating underworld of stalactites and sculpted cavern walls. One of the sinkholes is 65 feet wide and 400 feet deep! It takes about two full hours to explore this wonderland.

Take Some Time To Visit The Arecibo Observatory And The Rio Camuy Caves

When you come to Puerto Rico, make some time in your day to visit the Arecibo Observatory and the Rio Camuy Caves. This is truly a natural wonder. You will be so glad you took the time to do these two tours.

There are so many other wonderful adventures you can take while in Puerto Rico, and it is hard to decide just what to do while you are on the Enchanted Island.

I would highly recommend this day tour.

I think it is so cool that I get to see the world and never leave my writing studio. I have Hubbers like you who will show me all the sites for free.

Another wonderful tour of sites yet unseen. Thank you Mary!

Wow Mary, I was there with you ladies, under God's creation. Never heard of the Arecibo Observatory, but it looks like they mean serious business. love that Coqui, that only lives at the Island...as they say. What a big treat Courtesy of Cornell University. I reminds me when I was inside the Statue Of Liberty, and skipped the line, as a short cut to the top. :D Love the pictures and feel happy for you and your daughters. The caves are perfect for another out of this world scary movie. Though I would see stalactites, but they look like quaternary aged basalt. Wonderful trolleys! That's better than a made up cave from a Disney Theme! Congrats Mary!

Mary,

That was an awesome journey for you, and I know you enjoyed it. Because I enjoyed it with you just now. What a great trip to share with your family, and to be nice enough to share with us.

I voted everyway I could for this one.

Your Hub Friend,

BobbiPurvis

Hi, billybuc. Yes, just come along with me and my two daughters and we'll take you all over Puerto Rico! We'll even take you to Costa Rica if you want to go there, too.

Thanks for reading and taking the time to comment.

Hi, Lord. Thanks for taking the time from your busy day to read and comment on our trip to the observatory and the Camuy Caves. I enjoy all of our day tours, but this one was outstanding. I loved those spooky caves. Yes, that little Coqui frog sings all night long!

I'll be boring you with yet another day in PR.

Goodnight, Lord

Hi BobbiPurvis. Yes, this trip was a once in a lifetime trip for me and my two daughters to Puerto Rico. I did go back alone this past winter for 3 weeks (wrote a Hub about that trip, too). I just love PR. I'd like to live there.

Thanks for the vote, I appreciate that.\

Goodnight, Mary

I'm familiar with Arecibo and hope to visit it some day but did not know about the caves. It would be fun to combine a visit to a high tech wonder and a natural wonder in one day. Voting this Up and Useful.

Wow, am I tired, mary. I just took all those tours with you three and I'm exhausted. Your photos and descriptions are excellent and definitely make readers feel that they are right there with you. So happy you are enjoying yourselves. Bet you slept well that night.

Hi, alocsin. How are you familiar with Arecibo? This truly was a wonderful day doing both these tours.

Thanks for reading and commenting, and for the votes, too.

Goodnight, Mary

Hi jpcmc. Nice to see you! Yes, it was a great adventure. Puerto Rico is full of wonderful adventures; too many to see in one trip, really. I did go back by myself (wrote a Hub about that) and spent 3 weeks.

Yes, we just mingled with the crowd and got a fantastic lunch.

Hey there, drbj. I'm so happy you are following along with us on our trip to Puerto Rico by reading my Hubs. Wish you could have been with us in person! My description can not do this place justice, though. As you can tell by now: I love Puerto Rico!

Goodnight, Mary

Mary,

This place seems beautiful! I voted yes for sure! Didn't even have to think about it! :) I loved your pictures, and that lunch looked fantastic! Do you have some leftovers for me? :)

That bronze statue was pretty cool too! All in all, an excellent place and review! You did great here! The pictures, the clarity and the informative approach! Thanks for sharing Mary and take care!

I have never had to opportunity to visit Puerto Rico...yet but your hub and photos are a great place to start. Well done. I can't wait to actually experience Arecibo for myself. Thanks again. Voted this hub up!

Hi Mary,

You have me up after midnight watching all of these great videos. I was hoping that you would have visited those Camuy Caves. Have read about them and they look fantastic. So different from Carlsbad Caverns in New Mexico which is all underground. Getting to see daylight and even waterfalls with that large sink hole makes this cave truly unique. The Arecibo Observatory looks really interesting. Lots of steps getting to the actual dome which I am sure tourists only view from a distance. Thanks for another great tour of portions of Puerto Rico. You and your daughters have enjoyed some fantastic vacation experiences together. Nice! Lots of up votes and sharing.

Hi Josh, thanks for reading and commenting. The bronze Coqui frog honors the little frog that seems to only live on the island of Puerto Rico. He sings all night. Multiply that by thousands of sounds!

Thanks for the vote, and the nice compliment on my Hub,

Mary

Hi pointtomake. Nice to see you today! If you ever have the chance to go to Puerto Rico, please go. You will not be disappointed. They have so many things to see and do. It is indeed, the Enchanted Island.

Thanks for the vote, I appreciate that.

Bye for now, Mary

Hi Peggy W, thanks for taking the time to read and leave such a nice comment on the Arecibo Observatory and Rio Camuy Caves. These caves are just one of many natural wonders in Puerto Rico. What an adventure that was going down into the caves. I had read about the observatory, and was anxious to see that. No, visitors are not allowed on the actual platform, but I thought it was interesting to see the workers walking along.

Thanks so much for the vote and the share!

Have a great day, my friend, Mary

Mary, the more of your journey I see the more I want to visit Puerto Rico. The observatory looks very interesting but the Camuy Caves would be an absolute must for me - so cool!

Hi, Mike. Thanks for coming along with us to the Observatory and the Camuy Caves in Puerto Rico. I hope you will go to Puerto Rico, and enjoy all the wonders there. I loved it (can you tell by my Hubs on PR?)

So good to see you today, Mary

Mary, I never get bored reading about great vacations :o) - I read your cruise hub as well and the next time I went to look for it, it was unpublished! Is it back on HP yet?


mary615 profile image

mary615 4 years ago from Florida Author

Hi, Jools99. Thanks so much for coming along with us on our six day vacation in Puerto Rico. Yes, the cruise was on Day three, and it's back. You will find the link here on this Hub. I had a little problem with HP on that one, but it was republished. It was my fault, NOT theirs. I'm trying to make links between the days as they are published. Day 5 of our zipling tour will be published soon. Thanks again for reading about our adventures in Puerto Rico.

This is another enjoyable travel hub, Mary. What wonderful luck that you visited the observatory on the day of a celebration and got to eat a great meal! I love the photos of the caves. There are so many places that I would like to visit, but I know I won't make it to all of them. I'm very happy to be a virtual traveler and explore the world by reading hubs like yours.

mary615 4 years ago from Florida Author

Hi, Alicia C I'm so glad you found my Hub enjoyable. Just put Puerto Rico on your "bucket list". It is truly a wonderful, beautiful island. This day we spent at the Arecibo Observatory was very educational and the visit to the Camuy Caves was too.

Thanks for reading and commenting.

Goodnight, Mary

Hi, teaches12345. Yes, we had a lot of fun in Puerto Rico. I'm anxious to go back this coming winter. This tour of the observatory and the Camuy Caves was very educational. You would enjoy this one a lot.

Puerto Rico has so much to offer in the way of beauty and just natural wonders.

Thanks for reading and commenting today, Mary

I can't believe this was only a six day vacation...you packed in two weeks worth of activities it seems. It also seems you didn't miss much. Like Bill I have to say thank you for taking us along.

Your hubs have been so descriptive and your pictures so beautiful it made me feel like I was there with you! Thank you.

Voted up, useful, beautiful and interesting.

mary615 4 years ago from Florida Author

Hi, iamaudraleigh. When you go back to Puerto Rico, I'd suggest buying a copy of Frommer's travel guide to PR. That was our Bible! I am looking forward to returning this next winter.

Thanks for reading, and by the way, you did a good Hub on your vacation to Puerto Rico!

Thanks so much for the share, Mary

mary615 4 years ago from Florida Author

Good Morning, tillsontitan, thanks for going along with us on our vacation to Puerto Rico. This day touring the Arecibo Observatory and those Camuy Caves was an outstanding day for us.

I think you could spend three weeks in Puerto Rico and not see everything PR has to offer.

Thanks for the votes; I appreciate that, Mary

I would love to see the Arecibo Observatory! So glad to referenced it's starring role in 007 Goldeneye. One of my fave Bond flicks! It was also featured in the X-Files (I think it was the Little Green Men episode).

Wasn't familiar with the caves. Incredible photos! Thanks for sharing. Voted up, beautiful, interesting & awesome!
