Nimo is our guide, driver cum photographer for the day. She is a knowledgeable guide, skillful driver and takes great photos for everyone in the group.
The time span on each sight was adequate. We enjoyed our seafood noodles and pancakes recommended by Nimo. Overall we had a great time, despite an earlier warning of strong wind forecast.
