Europa Point, Gibraltar

The southernmost tip of Gibraltar, where the Mediterranean meets the Atlantic, with a red-and-white lighthouse and a view across the Strait to Africa, just 21 km away. The Ibrahim-al-Ibrahim Mosque and the Shrine of Our Lady of Europe stand nearby, along with old gun batteries.

It's free, and an easy bus ride from the town centre. On a clear day, the mountains of Morocco look close enough to touch, and you can watch the ships passing through one of the busiest shipping lanes in the world. Dolphin-watching boats leave from the marina.
