Andalucia is a mecca for anybody who enjoys sports. Here we have chosen 20 extreme sports, that is sports that can be taken to extreme, and dangerous, lengths. Many however, in their less extreme guise, are great adventures for beginners, kids and families. For adrenaline junkies, well, you will not be disappointed. From BASE jumping off high cliffs, to swimming underground lakes in deep caves, from skiing in the Sierra Nevadas to water skiing on the Mediterranean Sea, there is something here for eveybody. Please make sure to take the proper precautions, local advice where necessary and act sensibly.
