There is no easing into a bungee jump. You climb up, you shuffle to the edge, and then you either jump or you do not. Most people jump, eventually. What follows is a proper freefall and a bounce, and a rush that takes a while to wear off.
The whole thing rests on careful safety work. Jumps run from cranes, bridges and platforms, with the rigging checked and rated for every jumper and a trained crew running each one. You need no experience at all, just the nerve to let go.
The operators on adventuro handle the technical side, so all you have to deal with is the looking down. Be warned, plenty of people come straight back up the steps to do it again.
