Rail trails are multi-use paths created from former railway corridors. These trails are often used for walking, biking, and jogging, providing a safe and scenic way for people to enjoy outdoor activities. They typically feature a flat, wide surface, making them accessible for users of all ages and abilities. Many rail trails are part of larger networks that connect communities and natural areas. They often pass through picturesque landscapes, including forests, rivers, and fields, allowing users to experience nature while promoting healthy lifestyles. Popular examples of rail trails include the Katy Trail in Missouri and the Great Allegheny Passage in Pennsylvania.
