Castle Hill is in Newport Rhode Island and protects the eastern side of the east passage into Narragansett Bay.  It’s technically on private property, the Inn at Castle Hill owns all the access, but if you’re there during the day just stop in the bar for a drink and they won’t mind you wandering out to the light.  They will come and kick you out if they find you there in the middle of the night, or so I’ve heard.
