Really unique architecture in a wonderful location on Lake Michigan. Be sure to drive by and take in the site while you are visiting.

This is not a public attraction to enter, but it one of the magnificent Earl Young stone homes in Charlevoix. It is the most magnificent one in Boulder Park area and is across from Lake Michigan and is well worth a stroll by. It is available for vacation rental and is also for sale, I believe.
