Why now? Because Raymond Visan, the man behind Buddha-bar, the international chain of glam bars and restaurants, has turned his attention to detoxing. Opening at the end of this month, the eastern-themed Buddha-bar Spa at the Hilton Evian les Bains (hiltonevianlesbains.com) will feature pools, saunas, exercise studios, scrubbing rooms and a hamman overlooking Lake Leman.

Getting there London-Geneva via Paris by train from £110 return (raileurope.com, 08708 371371). Then train or taxi to Evian.

Where to stay Rooms at the hotel start at £117 (£153 for a lake view), including breakfast (must be paid in advance).

Where to eat Retox at the hotel's Cosmopolitan Bar then head to Le Campagnard (1 ter Avenue Anna de Noailles) in Evian for fondue.

What to buy Nothing. You'll be too busy realigning your chakras (and your bank balance).
