What's the attraction?
It's odd, really, the way we all rush towards the sea at the very first sign of some fine weather. Why head for Europe's fringes when you can bask in crisp sunlight in its spectacular ridged interior?
The Continent's classic lake-and-mountain combination has plenty to offer, whether you want to go hiking, biking or just relax. And it is never better than just about now.
Even after a record season of bumper snowfall, winter is starting to release its grip on the mountains: everything is starting to thaw, the wildflowers will be coming into bloom and the prices are right: lower than the ski-season, and not yet at their summer peak.
France is ruptured by two main ranges: the Alps and the Pyrénées. Alastair Sawday's Special Places (01275 395430; sawdays.co.uk) offers boltholes in both.

"Consider the weather: ideally you want warm days, suitable for walking or cycling in shorts and T-shirts. For activity holidays, gradings are crucial; know what level to expect from the outset. Know what you want, too – there are still traditional chocolate-box villages, but "new" destinations are emerging, such as Croatia and Slovenia, where you experience nature in its rawest form." Catherine Crone, Headwater (0845 564 9078; headwater.com)
In Switzerland the mountains are unmatched, the standards high – and visiting there doesn't have to cost the price of a Patek Philippe.
