New Yarmouth occupies a plateau 244 metres (800 feet) above West Advocate overlooking Advocate Bay, a branch of the Bay of Fundy. The highest point in Cape Chignecto Provincial Park is located on a summit of 275 metres (900 feet) just north of the New Yarmouth fire tower. McGahey Brook and Mill Brook have their source at New Yarmouth, draining south to Advocate Bay through deep ravines, while Copp Hollow Brook also begins at New Yarmouth, draining to the north. An abandoned log pond and several beaver ponds are found near the source of these brooks.
