Carol, I don' know where Galis Bay is but say I am at the West Indian Mall in Marigot on the waterfront, I continue past O'Plongeir Restaurant all the way along the seafront past the gas station on the right until I come to a roundabout and go round it and turn left to GC for example and therefore miss so much traffic on the normal route through Marigot. (You probably know all about this anyway) Terres Basses to GC with a good run, about 20-25 minutes tops. Would also just love to visit Le Piment one day but just found the journey too long from where I normally stay and dont much care for coming back late at night. Also you say on the French side you are staying, where abouts if you dont mind me asking?
