If you love rivers and the outdoors and aren't afraid of getting wet, a rafting trip might just be the watery adventure you've been looking for. Ply your paddle and work some muscles as you and your crew skull along tranquil family-friendly Grade 2 rivers, or hurtle down the natural big dipper of a Grade 4 rapid. Choose from a spectrum of journeys, from short taster sessions that will take you only a couple of hours, to fortnight-long rafting epics where you'll paddle for hundreds of miles and sleep under the stars. Costa Rica or NZ, the Sun Koshi River in Nepal or the Grand Canyon in the US: there's no shortage of wild, wet, wonderful white-water destinations. You could even try "black-water rafting", following your guide along underwater rivers and through pitch-dark caves in an inflated tyre inner. That sense of achievement will be all the greater when you burst back out into the sunlight!
