1. Grand Canyon National Park, United States

Sign up for a single- or multi-day excursion on rivers that wind through America’s most astounding natural wonder — the Grand Canyon. Spend hours, days — even weeks — on a professionally guided tour of waterways that range from placid to downright wild. Start at Glen Canyon Dam at the northeast part of the gorge and, from there, let your tour director — or your own paddle, should you choose — be your guide.

2. Ottawa River, Canada

The Ottawa River does a lot more than distinguish the border between Quebec and Ontario. The behemoth waterway is also Canada’s most popular destination for rafting and kayaking. Luke-warm waters attract families and die-hard rafters each summer to steer through a valley thought to be more than 175 million years old. Take the kids for a leisurely paddle, or put on helmets with more competitive friends and race down the wondrous archipelago at top speed.

3. Glacier National Park, United States

Travelers aiming to combine whitewater rafting with other outdoor excursions need look no further than Flathead River in Montana’s Glacier National Park. More than a million acres of preserved ecosystem and 700 milesof walkable trails make this nature lover’s paradise an ideal spot for hiking and, of course, rafting. Pilot your inflatable vessel along the 158 miles of pure, unadulterated water, sourced directly from the Rocky Mountains

4. Magpie River, Canada

It’ll take you eight days to steer the escalating rapids of Quebec’s Magpie River. Pitch a tent along this scenic stretch of river and savor its splendor, including the northern lights, in between day-long floats. Grade V rapids — the toughest classification recommended to raft — will greet you at the end of your week-long journey at Magpie Falls, a 125-foot vision of cascading water.

5. Pacuare River, Costa Rica

Also known as the Rio Pacuare, Costa Rica’s Pacuare River is a delightful escape with varying degrees of difficulty that last approximately 67 miles. Divided into the Upper Upper, Upper, and Lower sections, the river’s range of difficulty spans from Grade II to V – perfect for novice and veteran rafters alike. Surrounded completely by acres of lush rainforests, sailing down the Pacuare toward the Caribbean may mean introducing yourself to Costa Rica’s wildlife, like monkeys, exotic birds and jaguars.

6. Futaleufu River, Chile

Arguably the best river in the world for experienced rafters to tackle, Chile’s Futaleufu River offers both spectacular views and intense rapids. The stream, which cascades from lakes in the Los Alerces National Park and the Andes Mountains, is renowned for its deep-blue waters and Grade V drops. Recommended for skilled rafters with years of experience, the Futaleufu serves up long stretches of excitement at a time like the Wild Mile, a series of rapids that’ll keep any athlete on his or her toes — scratch that — seat.

7. Apurimac River, Peru

Earning bragging rights for rafting part of the world’s largest river is reason enough to fly to southern Peru for a rafting trip this year. The Apurimac River sources the Amazon, providing kayakers and whitewater rafters a chance to see South America’s magnificent wilderness up close. Grade IV rapids — and a four-day commitment — attract skilled rafters with an appreciation for camping and the great outdoors.

8. Zambezi River, Zimbabwe and Zambia

Only expert rafters should attempt to tackle the intense swells and challenging rapids that the Zambezi River is so wildly famous for. Separated into the upper and middle Zambezi by Victoria Falls, one of the Seven Natural Wonders of the World, the river is nearly 1,600 miles of nature at its finest. Look for hippopotamuses and crocodiles along calmer stretches of the river, and brace yourself for massive drops and death-defying rapids along the no-nonsense parts, including the Batoka Gorge.

The White Nile, a tributary of the actual Nile River, flows through Sudan, Rwanda, Tanzania and Uganda.

Grade V rapids ease into harmonious currents, promising rafters both relaxation and thrills in a single afternoon.
