If we had a base in the east and one in the west, do you think four nights at each would be enough to see the major attractions?
I'm thinking that's up to the stamina of the camper. How much can you cram into one day?

The lighthouse itself is fascinating. Take a picnic lunch and water with you. Here's more info on how to get over there.
