The Pacific North West is a fabulous holiday destination.

British Colombia in Canada is host to Vancouver, one of the world's most scenic and engaging cities and the glorious mountain resort of Whistler.

Washington state includes Seattle and the magnificent Mount Rainier plus a fabulous rainforest in Olympia National Park.

And Oregon has got it all - a stunning coastline, massive sand dunes, volcanic peaks and the glory of the high desert Sierra.

Dorling Kindersley's Eyewitness Guide to the Pacific Northwest (£14.99) includes the slogan 'The Guides that show you what others only tell you' and what it lacks in minute detail it makes up for by being packed with colour photographs, illustrations and maps.

If you are planning a holiday and want to ensure that you are going to see lots of lovely sights then this is a great travel guide.

There is more detail - but fewer images- in Lonely Planet's Washington, Oregon and the Pacific North West (£15.99). It's less spiky and opinionated than the Rough Guides but is easy to follow and helps ensure you don't miss the 'must-see' sights and attractions.

If you are heading to one of the most interesting and scenic parts of the American continent, then taking a copy of each of these books will definitely enhance your visit.
