A curious slice of Britain - picked up and plonked into the sun sea and sand of southern Spain - Gibraltar is a unique and historic peninsula crowned by the iconic Rock of Gibraltar mountain. Bright red phone boxes gleam Union Jacks flutter in the breeze and cones of fish and chips are scoffed in the sun in this most British of outposts. At times a surreal and strange juxtaposition you can be gazing at the African shoreline from the beach one moment and carefully treading across the runway of a crammed-in international airport the next. Gibraltar's cathedral-like Rock towers 400 metres above the waves and the stark limestone mountain watches out across a narrow strategic strait between the European and African continents. The pointed Rock is a symbol of this unique place and you can hike it - or take the convenient cable car - to enjoy the views and meet the mischievous colony of Barbary macaques who live on its slopes. Europe's only wild monkeys roam free and loose on the mountain. The Siege Tunnels bring to life the struggles for this land with the plucky British boring tunnels through the rock by hand effectively converting it into a giant watchtower capable of defending the distant territory. Natural caves inside droop with stalactites while a squat Moorish castle stands proudly at its summit. Grand Casemates Square is a sunbathed plaza and drizzly old Britain feels a world away as you sit back and sip ice-cold beers and cocktails in Gibraltar's historic centre.
