River-sledging in the Kawarau River has been named the world's top water adventure by Lonely Planet Great Adventures author Ben Fogle. Fogle rated the activity alongside rafting the Amazon River and kayaking with Orca whales in British Columbia.
The book also rates the Milford Track as one of the world's best 12 hikes.
Of the activity, run by Serious Fun River Surfing and Frogz White Water Sledging, Fogle encouraged readers to let the river ''have its wicked way with you''.
Serious Fun River Surfing managing director Neil Harrison said it was a great compliment for river surfing to be chosen alongside some of the world's best adventure activities.
