Editor's note: Founded in 1521, it’s one of the oldest cities in the Americas and a paradise for history and architecture buffs alike. And when you’ve had enough delicious food and shopping, El Yunque National Forest is a quick forty-minute drive from the city. It’s the only rainforest in the U.S. forest system, and can offer a nice respite from San Juan’s busy pace. Enjoy some cool San Juan wallpapers that show all that this accessible city has to offer!
