Arecibo Observatory Science and Visitor Center
Observatorio de Arecibo
Once home to the world’s largest single-dish radio telescope. After its reflector collapsed in 2020, the site became a science and education center where visitors can tour the exhibits.
The Arecibo Observatory was built inside a karst sinkhole. Its 305-meter radio telescope was once the world’s largest, and it appeared in the films GoldenEye and Contact. In December 2020, the receiver platform fell and was damaged. Today the site operates as a science and education center. The visitor center presents the history and scientific achievements of the observatory, and the viewing platforms overlook the sinkhole and the remaining structures. Opening dates and booking arrangements change frequently, so check the official website before you go. It is about 1.5 hours’ drive from San Juan and can be combined with the Río Camuy Cave Park and Cueva Ventana on the same day.
