The small borough of Califon, located along the Raritan River, features many homes on the state's historic register. It is a charming Victorian Village where the houses are marked with the names of the builders and their dates of establishment rather than with street numbers. Although famous for trout fishing, Califon does not allow fishing from one of the few remaining 19th century wrought-iron truss bridges in the heart of the village. Califon borders Lebanon Township and Tewksbury Township.
