The waterfalls along the Damajagua River, 30 minutes’ drive from Costa Dorada, have been transformed into an assault course worthy of an Indiana Jones movie. There are 27 water jumps from start to finish. You can slide down one, plunge off the next, and sail down a zip wire over another through dense jungle scenery. Then, you can take a well-earned break in a light-dappled rock pool. Helmets and lifejackets are provided as standard, though you should have a basic level of fitness.
