Trail crews are groups of individuals who work together to maintain and improve hiking trails in natural areas. Their tasks often include clearing debris, repairing damaged sections, and ensuring that trails are safe and accessible for hikers. These crews can be made up of volunteers, local organizations, or professional workers. In addition to physical labor, trail crews may also engage in planning and design work to create new trails or enhance existing ones. They often collaborate with organizations like the National Park Service or U.S. Forest Service to ensure that their work aligns with conservation efforts and environmental guidelines.
