Know More about this tour

After pickup from your hotel we will embark on a drive towards the Northern Karst zone of Puerto Rico.

Put on your helmet, grab your flash light (provided on tour) and head to Cueva Ventana. Window cave, as it is also known, is a series of caves located on top of a limestone cliff that leads to a panoramic, jaw-dropping view of the Rio Grande de Arecibo Valley. Originally a spot discovered and visited by locals, now accessible to everyone since 2012. During this moderate walk you will learn about its fauna, stalagmite and stalactite formations, and much more! The visit cannot end without the fabulous picture opportunities this natural cave opening offers.

After exploring Cueva Ventana, we'll go to the Arecibo Ionospheric Observatory. Built in 1963, it is a very important part of investigations of inter-spatial communications in the US. Nestled in the mountains, the observatory is home to the world's largest single dish radar/radio telescope.Scientists from around the world make use of the giant 1,000 foot-diameter dish to listen to the universe. 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 will 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 will also have an opportunity to see more than 25 various exhibits and see the dish!
