One of Beresford's main attractions is its beach. Renovated in the late 1990s, the beach features an observation tower overlooking the marshes, a boardwalk and change room, restroom and shower facilities. A popular tourist attraction, it is not rare to find local musicians featuring their talents at the beach on warm summer nights.

Every year a carnival called "Carnaval du Siffleux" is held in Beresford. Sculptures made of snow collected by ploughing parking lots are presented all around town. This is one of the many activities available to Beresford residents during this carnival. However, in recent years, fewer sculptures have been seen around the time of the festival.
