Gibraltar, Gibraltar

This British Overseas Territory on Spain’s southern coast is dominated by the Rock of Gibraltar, fondly called The Rock. For spectacular views, take a six-minute cable car ride to the top, where you can see two continents, two bodies of water and three countries. A short walk brings you to the Gibraltar Nature Reserve and the cheeky Barbary macaques, the famous monkeys that roam freely here. Other highlights include the illuminated stalagmites of St. Michael’s Cave and the Great Siege Tunnels, a maze of defensive fortifications carved into the rock in the 18th century and extended to an underground city during World War II, housing the garrison, canons, artillery and food. Another cave adventure is the Gorham’s Cave Complex, a UNESCO World Heritage site where rock carvings provide evidence of Neanderthal man dating back 120,000 years.
