I have seen better caves, but then, I have travelled to many places in the world. The cave tour was professionally done, no complaints.

The visit to the Arecibo observatory was interesting, but I wish they had announced clearly when the viewing of the film was about to start!!

Our guide from Castillo was friendly, helpful, he gave us ample time to have lunch in a nice restaurant after the visits.

I took this trip the day after my arrival in Puerto Rico, and this was a wonderful introduction to my stay. The rain forest is beautiful and impressive, I really enjoyed the walking.

Our guide Robert explained so much about Puerto Rico itself: its economy, its government, its politics. He was so interesting and enthusiastic that his talking alone would have made the trip worthwhile.
