Blanc du Nil is located at 15 Front Street, across from the Guavaberry Emporium at the head (eastern end) of Philipsburg, closest to the cruise ship terminal. The store is open Monday through Saturday from 10:00 AM until 6:00 PM.
There is another Blanc du Nil on the first floor of the Maho shopping plaza just past the airport on the western edge of the island. It stays open later in the evening.
