The lighthouse is the cape's essential stop. The old 1875 structure is a ruin, while the later 1925 lighthouse still marks the point for shipping and gives wide views over forest, village roofs, and the Atlantic.
There is usually a caretaker or local guide around, but arrangements can be informal. Bring small cash, ask before taking close-up photos of people, and give yourself time to enjoy the view rather than treating it as a quick tick-box stop.
