Castle Hill Lighthouse was very difficult to find. In fact, it took 2 trips. It turns out that there is a trail to it, but one has to know where to look and walk right up to the trail entrance to find it. That said, once one gets to the right place the trail is marked with a nice sign. And it was worth the hunt. Castle Hill Lighthouse is located on Narragansett Bay in Newport. The lighthouse was completed in 1890 on property formerly belonging to the naturalist, oceanographer, and zoologist Alexander Agassiz of Harvard University. Agassiz sold the land to the United States Government for the lighthouse for $1. His mansion on the property, commissioned in 1874, is now an inn (Castle Hill Inn). It was added to the National Register of Historic Places in 1988 as Castle Hill Lighthouse.

We accessed this lighthouse by going into the castle hill inn property, There was a guard gate but there was nobody in it when we went, but I see from other reviews that they seem cool if you say you are going to see the lighthouse. Then you go past the beach cottages on the left, there was a roped off parking area. I included a picture. The paths to get to the lighthouse are through the woods across the street from the parking area The lighthouse itself is cool and there is a stairs to get down to it. The views from the cliffs are incredible. If you have some time to kill, do this and then drive down ocean avenue.

Our GPS took us to the hotel to walk to the lighthouse. The actual parking for the lighthouse is not marked as such, but is a grassy area on the right as you go on the drive toward the hotel. Cross over the road and look for a dirt path through the trees. The lighthouse is beautiful.. an uphill walk to get there, then down. No access to inside. Really interesting, though. Worth the trouble.
