I would never go into white bay personally. Why? Not worth the risk. Go into Great Harbor, get your ball and hike. Its a great hike over the hill (no flip flops). If walking isnt an option, Id still prefer a taxi to the mooring field in white bay. What if you end up wanting to stay longer? What if you are intrigued by Gertrudes/Hendos/Ivans and decide to slowly make your way back?
