A great place to go that is not only interesting for people of all ages, but fascinating when you take the boat ride to the island and see the Boldt Castle...and a very good deal for the money!

We took our teen sons there and were fascinated by the elaborate architecture and the spellbinding story behind Boldt Castle. Definitely worth the time!
