The Top of the Rock offers the top sights of Gibraltar when you embark on a three-hour walking tour with a knowledgeable guide. Begin your adventure with a motorcoach ride that takes you around the Rock to view the huge catchment area and Catalan Bay. Then head up to the Upper Rock for your first stop of the day, a visit to St Michael's Cave. Here, you'll walk through a dramatic network of limestone caves located deep within the Upper Rock Nature Reserve. Legend tells that the first monkeys found their way to Gibraltar through a tunnel that linked these caves to Africa. You'll learn more about the famed Barbary apes on your next stop at the Apes' Den. Finally visit the Great Siege Tunnels, where you can walk in the footsteps of the leaders and soldiers who fought bravely for their country. You'll pass the Moorish castle and enter the heart of the city. You may choose to stay in town and do some duty­free shopping then return to the ship on your own.
