If you just drive to sightsee and turn on road to Planter restaurant then turn left after that follow road you'll eventually end up coming out a road that puts L"Oasis at your left and turn right at the end of this and there's Carol's store on left.
Or you can just leave PB area follow signs to Oyster Pond go past Pizza place on left overlooking Oyster, Les Balcons, road swings left and L"oasis on right, Carol's on left and just past that is BZH for great crepes and gallants. All the gendarmes eat there. At home we say where the cops eat must be good that's how we came to try it.
If you stay on this road it's a nice, pretty drive---some goats, chickens to watch out for then you'll come to some town where there's a maze of streets. We got lost ended up on a dead end at a school. Stay away when school lets out---kids & traffic! Eventually we came to a cross road with a laundry on left . We turned right and found ourselves on way to Orient, Le Gallion etc. We weren't lost at all. HA!
It's fun to explore the island, find new things, places. The worst that can happen is you reach a dead end. Once we took the road to the prison on PT Blanche---those guys have a great view!!
