Been both ways. Usually stay in Oyster Pond and do numerous visits to Orient.
There is a "coastal" route and an "inland" route. The inland route is a tad longer but quicker. The coastal route is much more scenic but lots of curves. Would recommend not doing the coastal route after dark.
Both take you thru Orleans on way to Orient.
To do inland route, head north form Westin. At bottom of hill take left (very first road you can do a left on), go up thru S curves and take a right on first large intersection/road you come to. continue to inland to rount-about. Take north exit out of round-about (you will see a Texaco and a MickyDees) you will head north and drive thru Orleans.
To do coastal route, do not take the first left, continue over the stream north and follow only major road. You will come out in Orleans, take a right.
From Orleans follow main road per previous instructions, past OB turn-offs, and watch for signs.
Note - the gas station close to Palm beach turn-off is recommended for cheapest gas - cash only.
