There use to be a path to head east to Peter Island resort and then walk through the resort to the beach. The resort is a re-construction site and is probably not that accessible.
I understand that the restaurant will be closed for a while longer.
the attraction at great harbour is the willy t.
If the restaurant is open, hopefully someone with more current information will chime in.
