San Juan is a charming city, lying south of Atlantic Ocean. Beautiful weather, rich history and breathtaking views make a difficult 24 hour destination - however, there are three places you simply can't skip 1.Start with Casa Bacardí - a gorgeous Bacardí facility producing 85% of world's Bacardí rum. It offers tours every day from 9 to 4 (10 to 4 on Sundays), and at $12 you get a fun tour and quick history of the facility and Bacardí in general, and a welcome cocktail - which, in my vocabulary translates to "a fun place to start a day". Count on at least an hour to get there and back, and another hour for the tour (unless you get carried away with the cocktails...), but it is surely a great way to start the day of exploring this wonderful city 2. Now that you have got you have had your pump of happy juice it is time to explore the heart and soul of the city - Old San Juan. First destination here - Castillo San Felipe del Morro. Also known as Fort San Felipe del Morro or Morro Castle, is a 16th-century citadel was designed to guard the entrance to the San Juan Bay, and defend the Spanish colonial port city of San Juan from seaborne enemies. It is now a historic site and at $5 is open for public every day from 9 am to 6 pm. 3. Walking distance from the castle is Old San Juan - oldest settlement within Puerto Rico. With its adorable colorful architecture, lots of local and international shopping and a variety of great restarts to chose from - it is truly one of the most beautiful and popular places in all Puerto Rico. It is famous for its colorful houses, fountains and statues, as well as countless stores and restaurants and you might want to spend most of your day here.
