Arecibo Observatory

Nestled in the mountains of northern Puerto Rico, about 30 minutes from Arecibo, is the world's largest radar/radio telescope. Here scientists from all over the world use a 20 acre and 1,000 feet diameter dish to listen to the universe. Visitors view the huge telescope from an observation platform, where its austere metallic symmetry shimmers in dramatic contrast with the dense green tropical landscape.

The Observatory is part of the National Astronomy and Ionosphere Center operated by Cornell University under a cooperative agreement with the National Science Foundation.

From Arecibo take Road 129 to 134, then Road 635 to 625, which ends at the observatory.
