3 out of the 4 days we were in Bar Harbor were foggy, but the day we chose to cross the land bridge was the perfect day and cleared up beautifully! Wear good walking shoes. We are in our 50s, and the walk up to the summit was fine. At one juncture, we thought the path had come to an end, but found a small rock pathway off to the right, which did end up at the summit. We had a clear view of Bar Harbor, the fishing boats, and the islands in the bay. Make sure you bring a camera with a panoramic function, as it is totally necessary to capture the beauty!
