The world’s northernmost capital, it's framed by the majestic Mount Esja, which keeps a watchful eye on the city, and the blue waters of Faxaflói Bay. On a sunny day, the mystical Snæfellsjökull glacier appears crystal-like on the western horizon, while mountainous moonscapes spread to the southeast.

Its panoramic view of the Cathedral and Castle is a relict of the Norman conquest and described as ‘one of the finest architectural experiences of Europe’.

Gran Canaria's more than the sum of its famous beaches, where holidaymakers assume the horizontal position to lap up one of the world's most-celebrated climates. It's not hard to see why capital Las Palmas de Gran Canaria was named after the island's palms. They are here, there, and everywhere. If you think of active sports in GC, you'll probably think of diving and surfing. But head to the island's interior to climb.
