You could just drive up there for a quick look at the view, but its $8 to park, so you might as well make the most of it! The lighthouse & buildings are lovely, and the museum really interesting. If you have paid to park then you can also have a free guided tour of the Lighthouse itself. Small groups of 10 are taken every half-hour and the Guides are delightful, knowledgeable, amusing & personable. 3 sets of 23 steps take you to the open terrace just below the light, and on a sunny day, the light dancing on the prisms is magical. Nie little cafe for refreshments too.
