Gibraltar is a British Overseas Territory located at the entrance of the Mediterranean on the southern end of the Iberian Peninsula. Most visitors arriving by sea are impressed by the rock’s huge visual impact. Only covering an area of 2.3 square miles (6.0 sq. km.) there’s several sites that need to be seen. Some of the “can’t miss” options include the Great Siege Tunnels, St. Michael’s Cave, The Moorish Castle, The Lighthouse at Europa Point and shopping – yes shopping. SeaDream docks at the passenger terminal and has the coaches for the land adventures just outside. It is an easy walk downtown to the duty free area. Bikes are available should you want to bike up the rock.
