Arecibo
Nature Preserve/Wildlife Refuge

The 268-acre Parque de las Cavernas del Río Camuy contains one of the world’s largest cave networks. A tram takes you down a trail shaded by bamboo and banana trees to Cueva Clara, where stalactites and stalagmites turn the entrance into a toothy grin. Hour-long guided tours in English and Spanish lead you on foot through the 180-foot-high cave, which is teeming with wildlife. You’re likely to see blue-eyed river crabs and long-legged tarantulas. More elusive are the more than 100,000 bats that make their home in the cave; they don’t come out until dark, but you can feel the heat they generate at the cave’s entrance (not to mention smell their presence). The visit ends with a tram ride to Tres Pueblos sinkhole, where you can see the third-longest underground river in the world pass from one cave to another. Tours are first-come, first-served; plan to arrive early on weekends, when local families join the crowds. Tours are sometimes canceled if it’s raining, as the steep walkways can…

There’s a picnic area, cafeteria, and gift shop. The caverns have been closed due to heavy damage from Hurricane María in 2017; do not visit unless you have verified that they have reopened.

  Bring a flashlight! This was a wonderful experience, but Hurricane Maria wiped out all the lights inside. There is no illumination inside the cave except for cell phone light. It is dark and slippery. Not recommended if you have any fear of darkness.
  Also, the trolley is not functioning. There is a 20 minute walk to and from the cave. I would recommend for older children (above 7) and physically fit adults.
  We brought a 10 year old, 13 year old and 16 year old. They loved the caves, but the 10 year old had a hard time walking back. The cave spiders were amazing to see! Our tour guide was great… fluent in both Spanish and English.

  A must see place just a bit over an hour west from San Juan. If you arrive with a small group by 9 you might be able to get a small tour but even the tour with twenty or so is pleasant.
  The guide was very knowledgeable of the cave system, history, of the flora, and the fauna.
  If you walk the whole thing, the tour is about 90 minutes. It’s easy going down and hilly coming up so be prepared with good walking shoes with grip. Your essentially in a rain forest going into a cave system.
  The caves themselves are impressive and beautiful. They’ve been here for millions of years before us and will be here for millions of years after us.
  Hurricane Maria destroyed part of the cave trail, and that part is closed off. But the rest of it is intact, minus lighting. Be sure to bring a flashlight 🔦 or use your phone 📱 as a flashlight. Charge your phone before you go because of that and all the potential pictures.

  So glad this is open again. Best to make reservations via email and be prepared for a hike to the caves n back up. Wear proper hiking shoes and bring a water bottle. You WILL need it. If you do have an issue making it back up the hill your guide will call for a ride if need be. Helps to be in shape 😀

  google.com/maps/place/?q=place_id:ChIJv5p9ebnEAowR0aLuhiqGvLM»>What an adventure. A lot of walking so be prepared. Take some good shoes, with grip. It’s VERY SLIPPERY in there. Let me repeat, VERY SLIPPERY. many people in my group slipped. There is railing but people don’t use it until they slip, then it’s too late.
  Tour guide with good. Informative, tried to be too funny, would have enjoyed more info. Can be dark in places. Take a flashlight if you have one.
  $18 for adults. $4 parking. Not bad. Didn’t expect this type of adventure in Puerto Rico

  The park is nice. Unfortunately the caves were damaged due to hurricane Maria that passed by the island and flooded the caves killing 99% of the bat population. The tour can only take you to a certain point thru the caves. The path was cut short and closed off because of what looked like a mudslide or rocks that tumbled onto it. In my opinion, the use of some lights would accentuate more of the rocks formations. It looks like there was a light system in place from before but the lights were out. The tour guide brought some lights and we were able to use the lights on our phones. Come with a full battery. In general, the experience was good, the vegetation is beautiful and the tour is very informative. It’s safe and good for older kids. I recommend to make a reservation or you might have to wait a couple of hours.
