Beaches are hotting up but for real heat without the cooling influence of the sea, head for the desert or a city near one. Online travel advisers Cheapflights (www.cheapflights.com) offers its top 10 desert city destinations: Las Vegas, Nevada Love it or loathe it, Las Vegas is the leviathan of desert destinations. It's a city of mega hotels: Mandalay Bay, New York-New York, The Mirage, Luxor, Bellagio, and Paris – all waiting to fulfil your fantasies. Four Corners It's the anti-Vegas. Remote and resplendent, pilots like to point it out from 35,000 feet. It's Four Corners - where Arizona, New Mexico, Utah and Colorado kiss. Back down to earth the view is more intimate. It's steeped in Navajo culture: arts, handcrafts, and ceremony. It's also home to a great resort called Amangiri. You get there via a winding road descending into a valley. Palm Springs, California It's the startling contrast of vivid golf greens amidst sandy surroundings that signals Palm Springs. Embraced by the ethereal San Jacinto Mountains are galleries, boutique shops, and authentic culture. The prime perch to take it all in is from the Palm Springs Aerial Tramway.
