These are used by bicyclists. Some are restricted to use by only non-motorized bikes while others are multi-use recreational (hiking, horseback riding, jogging, rollerblading or walking). Bike trails can range in length from under a mile to hundreds of miles, such as the EuroVelo routes, Australia's Munda Biddi or Bike Trails in North America.
These follow coast lines. A good example is the South West Coast Path in England.
These may be cross-country paths, or may follow roadways, or other ways, and often intersect with many other trails in the process. A good example is the Coast to Coast Walk in northern England.
Two good examples of mountain trails are the Appalachian Trail and the Pacific Crest Trail. The Tour du Mont Blanc, through the Alps of France, Switzerland and Italy, comprises about 170 kilometers (105 miles) of high-altitude hiking and usually takes 8-10 days.
Among the longest, the Trans-Canada Trail.
Among the longest is European walking route E8.
