THE FACTS ABOUT HELICOPTER TRIP GRAND CANYON
USA

WHAT
Ranging from 629 km wide and more than a kilometre deep, nothing can quite prepare you for the first sight of the Grand Canyon in Arizona - and helicopter is one of the best ways to appreciate this huge abyss of sandstone pinnacles, outcrops, ridges and chasms with colours that range from dazzling desert yellows and oranges to deep-purple shadows. Kuoni (01306 742888; www.kuoni.co.uk) can arrange a helicopter flight for you as part of its 14-night, self-drive Heart of the National Parks itinerary, which also includes Yosemite, Death Valley, Zion, Bryce Canyon and Monument Valley. If you want to organise a trip independently, try AirStar Helicopters (www.airstar.com) or Kenai Helicopters www.flykenai.com), both located near the Grand Canyon

WHEN
Avoid high summer when the Canyon is scorching and busy - it is best to go in the cooler months of spring or autumn
