I also made a reservation for a daytrip in the nearby mountains. We went in the early morning and met again near the Huanchan road, close to the office. A ten-seater picked us up and we left.
A small boat took us to the Kayak hiring station. We took three Kayaks in total, one for the guide, one for the couple from the US and one for us. We started rowing to a hidden Bay away from the crowds.
