Pentecost Island is most famous for being the spiritual birthplace of the extreme sport of bungee jumping, originating in an ages old ritual called the naghol, or land diving. Between April and June every year, men in the southern part of the island jump from tall towers (around 20 to 30 metres) with vines tied to their feet, in a ritual believed to ensure a good yam harvest. The ritual is also now used to show acceptance into manhood. It is possible to witness the ceremony, often during day trips from Port Vila.
