The trip from Phuket to Koh Samui took us all in all 7 hours. Unfortunately we missed a ferry so we had to wait one hour at Don Sak Pier. The route led us through Phang Nga area.Very spectacular montain view. The ferry took 90 minutes from Don Sak to Koh Samui.
We haven't been in Koh Samui for more than 10 years. The island changed a lot but it is still worth a trip. We prefer Lamai beach before Chaweng because it is not crowded so much. Next time we also will visit Ko Phangan and Koh Tao.
