Car Rental Gibraltar - Exploring Gibraltar
All of Gibraltar can be covered on foot, and much of it (including the upper Rock) by car or motorcycle. You can also ascend the rock by cable car.
A short drive, and well worth a wander, are The Great Siege Tunnels which were gun emplacements hand carved by the British during the 1779-83 siege.
Nearby is the Tower of Homage, the last vestige of Gibraltar's Muslim castle built in 1333. To get to the tunnels, walk to Princess Caroline's battery from the top of cable-car station on the Rock, passing as you go the Military Heritage Centre.
Another must see is St Michael's Cave, an impressive natural grotto that was once home to Neolithic inhabitants of the Rock but is today used for concerts and plays.
Many of the graves in the Trafalgar Cemetery are of British sailors who died at Gibraltar after the Battle of Trafalgar. From here head to Europa Point, the southern tip of Gibraltar, where there's a lighthouse, the Christian Shrine of Our Lady of Europe, and a handsome new mosque.
Upper Rock Nature Reserve, starting just above the town, has spectacular views and several interesting spots to visit. The Rock is home to 600 plants species and is often a fine spot for observing migrations of birds between Africa and Europe.
The Rock's most famous inhabitants are its colony of Barbary macaques, the only wild primates in Europe. Legend has it that when the apes disappear from Gibraltar, so will the British!
