Salt Kettle Bay Beach is in Northern Eleuthera and as far as I could find isn’t any longer accessible unless you were to walk through the brush. I believe there was an entrance at a fork in the road but that has been closed with a gate and a no trespassing sign. We always try to respect those types of things and I am grateful we had the drone to get a better look at it even if we couldn’t walk it.
The road is the last road on the right off the Queen’s Highway before you get to the Gene’s Bay dock to go to Spanish Wells. It’s a rough road and unless you really want to get there and trudge through the bush, I wouldn’t advise it. Or if you really want to get there- rent a boat.
