Arecibo Observatory

The Arecibo Observatory was the world's largest radar radio telescope for over 60 years, until in 2016 a larger one was constructed in China. It was operated by the National Astronomy and Ionosphere Center of Cornell University for many years, and today makes for a great visit for science enthusiasts.

Do & See

San Juan’s perfect mix of old and new sets the stage for an unforgettable trip. The starting point should be Old San Juan, where walking is the norm, but free trolleys are available to take visitors from one site to the next. Nobody who visits the island should leave without seeing the forts, the churches and the cobblestone streets of Old San Juan.
