An hour's drive from both Edinburgh and Glasgow, Gleneagles feels entirely self-contained once you're on the estate, a grand Scottish country house with big lounges, open fires and views rolling out over Perthshire. Three championship courses give the golf real range: the PGA Centenary, host of the 2014 Ryder Cup, sits alongside the more traditional King's and Queen's Courses for a mix of modern and old-school design. Rooms carry a proper five-star polish without tipping into showy, and the resort backs it up with fine dining, a spa, pool, gym and a long list of country pursuits, making it just as suited to mixed groups as to golf-only trips.
