Puerto Rico Part Six.
I am not much of an outdoorsy person and definitely would never describe myself as very adventurous, but I felt like a real Indiana Jones when we went exploring the Cuevas de Camuy, or the caves of Camuy. We went down a mountain into one of the longest chains of natural caves in the world, carved out by the Camuy River. It was so cool to be inside a cave looking up at all the beautiful foliage and seeing how plant life adapts to darkness.
After exploring the caves for a while we decided to head over to Arecibo to see the Arecibo Observatory which is an enormous single aperture telescope. I remember seeing this huge thing in the movie Contact and most vividly from an episode of X Files. It sits on top of a mountain in a rather remote location. The structure is HUGE. To give you an idea of scale, that arm looking thing that leads you out to the receiving head of the telescope is a walkway for people. Yeah. It's pretty big.
