El Morro Castle is beautiful! There is another smaller castle that we did not do. I cannot remember the name. We also went over to the Bacardi Rum Distillery. I would not do that again, it was not bad, just one of those things where you been there, done that. The streets are beautiful too. There is a lot of shopping not to far from the port. We got into San Juan at night and pulling into port was Beautiful. El Morro Castle can be seen when coming in as was all lit up. I am sure it is just a pretty coming in during the day if that is when you will be arriving.
