A few months ago, the towers of San Marcos were opened to the public. Climbing them allows you to see Salamanca in a very special light: there aren't many cities with such spectacular views to offer. I recommend the towers to visitors, not just for the views, but also for the panels that explain the local history. Once at the top, it's easy to pick out the different landmarks thanks to the information panels. It's not expensive, and really is a must-see in the city. Hours: January, February and March from 10:00 to 18:00 (last entry is at 17:15). From April to December 10:00 to 20:00 (last entry is at 19:15).
