There were no Fees. The view of Lake Champlain and the surrounding area from the gallery near the top of the lighthouse is wonderful, but you must be able to negotiate about 9 flights of stairs on a circular interior concrete staircase, and a short ladder at the top to reach it. There is an additional ladder leading to the cupola, but cupola access was locked. Ages 8+ would have no trouble reaching the gallery, but suggest not let under 12 go unless accompanied by adult. There is a concrete dock down from the lighthouse, but more stairs down and back up and not wheelchair friendly. I had hip replacement, but no trouble negotiating either by going slow.
