10. Bungee jumping - Pentecost Island is famous for being the birthplace of bungy jumping, originating in an age old ritual called the naghol, or land diving. AJ Hackett developed the modern bungee jumping from the ancient ritual of land diving on Pentecost Island. Between April and June every year, on a Saturday, men in the southern part of the island jump from tall towers (around 20 to 30 m) with vines tied to their feet. Despite being a little tricky to get to, it can be done if you want to watch this intriguing ritual.
