1. The Camel Trail, Cornwall
The Camel Trail is one of Britain’s most beautiful, unspoilt traffic-free trails. With 18 miles of coastal and countryside scenery running between Bodmin and Padstow it’s one of Cornwall’s top tourist attractions. Cyclists can follow the old railway track, explore the surrounding woodland and ride alongside the River Camel before arriving at the picturesque Padstow harbour. There are panoramic views along the way, and its flat and easy track makes it ideal for a family bike ride. The steam railway and wildlife will entertain the children, while parents can enjoy the wine tasting at the Camel Valley Vineyard, or you can all delight in the Cornish cream teas and pastries at the Camel Trail Tea Gardens.
Time: about 3 hours

2. The Rutland Water Cycle Way, Leicester
The 25-mile Rutland Water Cycle Way is 95 per cent off-road, and one of the most family-friendly cycle routes in the country. It’s a gentle, mostly flat ride with a few short slopes, making it doable for all ages. On the route around Rutland Water, which at 3,100 acres is the largest lowland man-made lake in Western Europe, cyclists can enjoy the fabulous waterside and Hambleton Peninsula views. The best route is the circuit around the Peninsula which also gives you scenic views of the reservoir shoreline. If you don’t want the hassle of taking your own bikes at Whitwell and Normanton, there’s a hire shop available.
