Vendors often moor their boats up on shore around lunchtime with a selection of breads, cold cuts, fruits and juices available for sale, too. There are sun loungers and shades provided onsite, but no toilets, so families with small children might want to consider going elsewhere.

    Beach vendors often patrol the beach, selling a variety of local food and drinks, but there is also a restaurant onsite which sells affordable small meals and drinks throughout the day. Like Reduit Beach, there are no toilets on this beach, so if you're holidaying with small children, you might be better off spending the day somewhere else.
