Much of the terrain is mountainous, wild and wooded, with some spectacular gorges; at 8913ft, the dramatic Hells Canyon is deeper than the Grand Canyon.

In central Idaho, the ski resorts of Ketchum and Sun Valley are beloved of affluent second-homers and celebrities. Ernest Hemingway loved the area’s tranquillity (not to mention the hunting and fly fishing) and is buried at Ketchum, where he spent the last few years of his life.

In the far north, bordering onto Canada, the panhandle region is famed for its lakes, watersports and angling; down south, adrenaline junkies take to the Salmon and Snake Rivers for whitewater rafting and kayaking.
