September 4-11, Hua Hin, Thailand
This quirky annual tournament began 10 years ago and has become one of the biggest events on the Thai tourism calendar.
It's played under strict rules developed by the World Elephant Polo Association, and raises money for the welfare of elephants, which hold a revered place in Thai history and culture.
The game is played on a 100x60m pitch and there are three elephants in each team, each carrying a mahout and a player.
The game comprises two seven-minute chukkas (halves) using two-metre mallets and a standard-sized polo ball.
