The Royal Military Canal Path is a long-distance path in England, mainly following the Royal Military Canal. Its end points are Seabrook, Kent ( 51°04′19″N1°07′20″E / 51.0720°N 1.1221°E ), and Pett Level, East Sussex ( 50°53′19″N0°41′02″E / 50.8887°N 0.6840°E ), and it runs for 27 miles (43 km). It is a canal-side path and fringes the northern edge of Romney Marsh. The canal is an early-19th-century defence against a possible invasion by Napoleon, and it is a Scheduled Ancient Monument and a SSSI. Links are made with the Saxon Shore Way at Appledore and West Hythe. [1] [2]
