There are likely few places in the world that you enter by walking or driving across an airport runway, but that's what happens in Gibraltar. First you show your passport; then you make your way out onto the narrow strip of land linking Spain's La Linea with Britain's Rock. Unless you have a good reason to take your car—such as loading up on cheap gas or duty-free goodies—you're best off leaving it in a guarded parking area in La Linea, the Spanish border town. Don't bother hanging around here; it's a seedy place. In Gibraltar you can hop on buses and take taxis that expertly maneuver the narrow, congested streets. The Official Rock Tour—conducted either by minibus or, at a greater cost, taxi—takes about 90 minutes and includes all the major sights, allowing you to choose where to come back and linger later.
In 2013, tensions between Gibraltar and Spain ramped up yet again, and as a result, lines for leaving the colony, both via car and on foot, are long—it can take up to three hours to cross the border into Spain. This is likely to continue, as there’s little sign of any progress on any sort of joint Anglo-Spanish sovereignty, which the majority of Gibraltarians fiercely oppose.
When you call Gibraltar from Spain or another country, prefix the seven-digit telephone number with 00–350. Gibraltar’s currency is the Gibraltar pound (£), whose exchange rate is the same as the British pound. Euros are accepted everywhere, although you will get a better exchange rate if you use pounds.
