Hiking is a recreational sport involving long distance walking in natural environments following trails that can be located on public and/or private land. There are many types of hiking trails, some for short distance day hiking and some that are miles long. Hiking can be done at a leisurely pace, moderate pace, brisk pace or fast pace and as a day hike or a longer hike involving much more intensive overnight hiking preparation, supplies and equipment. The trailhead marks the beginning of a trail and some trails may even have rest rooms, signs, information, level of difficulty maps, parking areas for vehicles and other amenities. Hiking trails can be found in: local parks, state parks, national parks, national and state forests, city and county parks, wilderness areas, nature areas, wildlife refuges and others. Equipment needed for hiking will depend on the length, pace, terrain, weather but in general the very basic requirements are: water, food, maps, hiking boots. Longer more strenuous, overnight or long duration hikes will require more equipment. Online stores specializing in hiking equipment and supplies and hiking departments within stores, generally have coupons, discounts, special offers, promotions for a wide range of hiking related items.
