Swallowtail Beach is a rocky beach on Grand Manan. Swimming is possible, but the Bay of Fundy's cold water and strong tidal currents require caution. Always be aware of the tide schedule, as the water level changes dramatically, potentially altering access and exposing slippery rocks. The beach is not supervised, so assess conditions carefully. Water shoes are recommended due to the rocky terrain.

To experience Swallowtail Beach with fewer crowds, consider visiting during the shoulder seasons (late spring or early fall) or on weekdays during the summer. Early mornings or late afternoons, especially closer to sunset, also tend to be quieter. These times allow for a more serene experience, perfect for enjoying the remote shoreline and views of the famous lighthouse cliffs without significant visitor traffic.
