Gibraltar is a British territory at the southern tip of Spain, dominated by a limestone ridge with tunnels, caves and a colony of Barbary macaques on top. The town below is compact, and the cable car or a steep walk covers the rest. Africa is visible across the strait on clear days.
The guides here cover Gibraltar as a whole. The border with Spain can involve long waits at peak times, and the road to the airport crosses the runway, which closes when aircraft move. The currency is the Gibraltar pound, tied to sterling, though euros are widely accepted. The macaques are wild and habitual thieves — food and bags need watching on the upper rock.
