As you enter Marigot, turn left at round about. As you turn, the cemetery will be on your right and water in front of you. Turn right and keep cemetery on your right. There may be a few parking spots on this road, but no parking in the blue zone (any parking spot that is outlined in blue) unless you have the permit from the rental car company. If there are no spots there, continue straight through until the Market is on your left. Go past the Market and the taxi / bus parking lot and turn left at the corner. As you turn, the West Indies Mall will be on your right. Continue and you will see public parking lot on your left. If that's full, continue straight and there will be another public lot with a shuttle bus to take you to and from the Market. Hope this helps.
