Relish the great outdoors and inhale the fresh air on a healthy retreat that features trekking or hiking alongside other activities. The retreats we have reviewed are set in safe and scenic places where walking trails are often right from your door, whether you’re staying at a spa in the foothills of the Himalayas in India or enjoying a hill walking and yoga retreat in Italy. Some of our healthy holidays make walking very much a part of the programme, while others offer the option of privately guided or solo strolls. In England there’s a plethora of places that offer gorgeous walks – they range from farming country in Dorset and the banks of the River Dart in Devon to forest walks in Kent and pretty Suffolk, where you can enjoy silent rambles or longer hikes. Head to Wales and climb the highest mountain – Mount Snowdon, then enjoy the summit and take in the views, or admire the stunning, wild landscapes in the Scottish Highlands. On a private island in Greece explore 60 acres of land, where tracks criss cross the terrain, or go to the Swiss Alps and tackle those stunning mountain paths. You’ll emerge fitter and full of energy.
