There was a short and paved loop trail at the top, about a half kilometer. I was the only one on the bus to walk it. You could barely see a thing, but it felt good to have boots on the ground in Maine (home once in a past lifetime for a lot of years) once again!
You could see relatively clearly for maybe 20 feet, and after that shapes looked like ghosts. Because of the paved path, you really couldn't get lost:

Even these pretty purple flowers were muted by fog:
Back at sea level, I snapped a shop of Bar Island. At low tide, as it is now, you can walk to the island across this bar that gives Bar Harbor it's name. It is a popular thing to do, as you can see. But stay alert, because if the tide comes in - 12 foot range - you'd better be able to swim in the 50 degree water, or you're staying on the island for a while.
