The only wild monkey population of Europe is roaming free on the Rock of Gibraltar. Because they are wild you can never exactly say where they are although the top station of the cable car and the St. Michaels cave are popular spots. Be careful with them, they are most likely more than willing to pose for your pictures, but they can also be quite cheeky. No bag, plastic of sunglasses are safe when entering the apes territory.
