The Seaton Tramway is a 2 ft 9 in (838 mm) narrow gauge electric tramway in the East Devon district of South West England. The 3-mile (4.8 km) route runs alongside the Axe Estuary and the River Coly, running between the coastal resort of Seaton, the village of Colyford, and the ancient town of Colyton. For much of its route, it operates between the estuary and the Seaton Wetlands nature reserves, offering views of the wildlife of both.
