Between the summer sun and winter sports, these Swiss resorts show off their multi-coloured beauty, says Zoe Dare Hall. Swiss resorts, like all Alpine destinations, are increasingly talked about these days in terms of their dual-season appeal. It's part of the push to get visitors and property buyers to see them as a summer destination as much as a place that's about hurtling down snowy slopes in winter. But the real star of the show is autumn. The vast, multi-colored land-scapes - and lack of crowds - make this the most Instagrammable of seasons, yet it's still something of a secret. Think deep, glassy blue lakes and flame colored trees, hazy sunlight that bathes the valley floor and white-capped mountains beyond hills of brilliant the green.
