I did a lazy boat trip on my last day Which stopped at Trunuc in the afternoon
It cost £10 to include lunch and unlimited drinks. To book go to where all the trip boats are towards the marina. I dealt with a guy called Kebab! A great day. There also might be boats that take you straight there, I know they run to and from Icmeler. They will be cheaper as they are like a water taxi. Andrew
