A karst area has a variety of above-ground karst features. Some are easy to recognize, such as natural bridges or sinkholes. Karren are more difficult to identify, and dry valleys or swallow holes are usually very difficult to recognize. In recent years, many municipalities have started to establish themed hiking trails.
