A word to the wise. On some islands marked private. You may have every legal right to move along the tidal range on paper. You may be greeted warmly and politely by staff. Maybe by the guest's or even owner's private security detail. The one do not want to meet is a security canine who is trained to look for people who are not supposed to be there and look like they are sneaking in by boat. I have not witnessed the dogs of Necker. There are security dogs in other places in the BVI and across the caribbean. More than one explorer has jumped into the sea from Guana thinking no one would notice a couple of hikers.
