What's the story?

World's Most Scenic River Journeys.

Tell me more.

Exactly what it says on the tin: a new six-part documentary series tracing the courses of remarkable rivers and the stories of those who work and live in and around them. The odyssey begins with a trip down the Niagara River to the famed Niagara Falls.

In a barrel?

I wouldn't advise it. But over the coming episodes you can hitch a ride on a fishing boat, yacht, canoe and even a replica Viking ship.

Why is Niagara special?

Well, 3,160 tons of water flows over Niagara Falls every second. Four of the five Great Lakes – Superior, Michigan, Huron, and Erie – drain into the Niagara River before emptying into Lake Ontario.

Anywhere closer to home?

The second episode – due to air on April 9 – visits the River Spey, renowned for its stunning scenery, salmon fishing and whisky production.

The programme shines a spotlight on some fascinating tales, be it the biologists counting the young salmon population along a stretch of the 107-mile river or the wild swimmers braving the morning chill in the glittering waters of Loch Insh.
