Havre de Richibouctou, or Richibucto Harbour, is a significant tidal estuary and coastal harbor system located on New Brunswick's Acadian Coast. This expansive saltwater environment is characterized by a network of channels, flats, and bays that are heavily influenced by the powerful tides of the Northumberland Strait. The harbor serves as a vital ecological zone where freshwater from the Richibucto River mixes with the saltwater of the Gulf of St. Lawrence, creating rich feeding grounds for a variety of marine species. The surrounding landscape features low-lying, marshy shores and sandy points, providing diverse habitats and angling opportunities from both boat and shore.
