White water rafting is a sport that people all over the world participate in. I was introduced to water rafting by a family friend of mine, and its one heck of an experience. You go rafting once, you'll want to go again.
What is a rafting holiday all about? Basically you will be traveling down a river by the only method suitable - a raft! This means that you can gain access to places that cannot be reached by motorised pleasure boats or even by intrepid hikers. You will therefore be rewarded not only with the thrills of fun whitewater but also by pristine wilderness, exotic wildlife and small villages unspoiled by mass tourism. Sound OK so far?

As a beginner you would only be expected to run rapids up to a grade 4, or even grade 3, also check to see what your insurance cover will cover you for. Most policies only cover to 4 as standard.
