Hiker

A hiker is a person who engages in hiking, a pedestrian form of travel on natural terrain, typically on trails or backcountry paths. Hikers pursue recreation, exercise, or transportation, and may travel for a few hours or days. They range from casual day hikers to long-distance trekkers who complete multi-week or multi-month routes. Long-distance hikers are often called thru-hikers when attempting to traverse an entire long trail in one season.

Hiking as a leisure activity developed in the 19th and 20th centuries with the growth of national parks and outdoor clubs. Modern hiking emphasizes accessibility, safety, and stewardship of the environment. Backpacking is a related activity that includes overnight camping and carrying gear such as a sleeping bag, tent, and stove.

Typical gear includes sturdy footwear, moisture-wicking clothing, a daypack or backpack, navigation tools (map, compass, or GPS), water and food, weather protection, and basic first aid. Safety considerations include checking forecasts, staying on marked routes, knowing personal limits, and practicing Leave No Trace principles to minimize impact on natural areas.

Hiking cultures organize through clubs, trail associations, and online communities. Well-known long-distance trails—such as national or regional routes—attract hikers who plan sections or complete through-hikes. Hikers interact with wildlife and may encounter varying terrain, from deserts and forests to alpine environments.
