Observatory Science and Visitor Center
This scientific haven was once attached to the world's largest radio telescope, which has sadly been pronounced defunct recently. However, over 100,000 visitors check out the science center every year, with information about the radio telescope's history, accomplishment, and ultimate ending. Besides all the valuable information here, the way up to the center is a steep climb with some of the most beautiful views Arecibo has to offer. This is a must-do for folks in STEM and for families with children interested in the field!
