Africa’s most exhilarating rafting is found on a 24km stretch between the narrow walls of Batoka Gorge, via 23 terrifying Grade IV and V rapids such as the “Gnashing Jaws of Death”, plus some huge drops. The put-in point on the Zambezi River is at Victoria Falls, the world’s largest waterfall by volume, making this among the most dramatic surroundings you can get while sitting in an inflatable raft.

You can take in unique perspectives of the Grand Canyon from the wild Colorado River, which runs for 226 miles (363km) through Utah and Arizona , on this hair-raising rafting trip down class IV–V rapids in the world’s deepest gorge. You can mix things up with visits to ancient Navajo ruins and side grottos, or with hikes to spectacular waterfalls. If you don’t feel up to a full-on eighteen-day belter, three days is usually the minimum to really get to grips with the river, though some companies run half-day or day excursions too. Vessels vary from motorized, oared or paddle rafts to little wooden dories, and the season lasts from May to September.
Rafting down the Magpie in eastern Québec offers the chance to see more than just stunning secluded forests, intriguing wildlife and the impressive Magpie Falls – you might also catch a glimpse of the wonders of the aurora borealis.

The rapids get increasingly more aggressive and difficult to navigate as the eight-day trip downriver progresses, climaxing in Grade V rapids on the last day at Magpie Falls.
