The beach where they filmed The Beach in the Koh Phi Phi islands. We stopped in the bay one lunch time and a few of us went ashore in the dingy. It was really nice, beautiful white sand and turquoise water but about a million boats and tourists. It was still great to see though. We went a bit in land also and followed a sign to another bay which when we got there was just a puddle surrounded by rocks! It was the most rubbish bay I have ever seen. LOL :-)
