Clayton Island Boat Tour and 2 Nations Tour - Liam was an amazing boat tour guide for Clayton boat tours! He was very knowledgeable and really seems to enjoy his job very much. It should be noted that you will get wet on this boat tour due to wind and choppy waters. But overall, it’s very beautiful and has a rich history. Also, notable is that when you buy the boat tour to get to the castle you’ll still need a ticket to tour the castle. Both are worth every penny.

beautiful scenary but lacking tour - The water was very beautiful and castle was stunning. But the tour itself is lacking. The motor was loud and it's hard to hear what the tour guide was saying. The narration was dry and boring. In addition, both the tour guide and the captain had an attitude that, frankly, does not fit into the service industry. I asked the tour guide a question and was brushed off. And my husand, who talked quietly with a friend, right behind the captain, was told by the captain to stop chatting.
