If it's varied scenery you're after, then hop on your bike and explore the Devon Coast to Coast (National Route 27) trail, taking in estuaries, moorland, woodland and market towns. This 100 mile (160km) route between Ilfracombe and Plymouth was the first Sustrans cycle route to be created, 40 years ago in 1967. 10 miles (16km) of this route goes through the Plym Valley, following the old Great Western railway line. Nearly half of the route is along traffic-free, former railway lines, making it great for the whole family.
