The Bacardi rum distillery was fun & interesting! Located 15 min from San Juan, you need a car or hire a cab to get there.
The Arecibo observatory is the largest radio telescope in the world and they have been analyzing radio signals from outer space since 1963! It was hard to get to, but I am happy I saw it.
Our trip was good, but we ate lots of fast food and I feel that it was very expensive for what we got.
