Spain has its fair share of "must visit at least once in a lifetime" festivals, such as La Tomatina. However, if you're a daredevil, you might prefer Los Sanfermines. This festival is most famous for the bullrun where a group of thrillseeking participants try to stay ahead of a number of bulls for a 875 meter parcour that stretches towards the bullring. The aim is to get close in front of the bull and maintain your position as long as you can. If you can't outrun them, you can pull to the side and let them pass. Running with bulls is, as you can imagine, not without risk. Injuries are common, and although rare; there has been a number of deaths over the years.

Traditionally, Sanfermines is a religious festival. If you visit now you won't see that many churchgoers but instead people dancing, drinking, eating and partying. So if you're not excited about the idea of being chased by bullls, there are lots of other activities to join!

Would you dare to participate?
