National Parks in Puerto Rico
National Historic Site, San Juan, PR
The massive fortifications, cannons, dungeons and turrets overlooking the azure Caribbean are a sight to behold, but there’s more hidden underground. A network of “secret” defensive tunnels runs below the fortifications of Castillo San Cristobal, and only two 15-person tours are given every weekend to those who sign up first.
