I had not that high expectations on the Island to be honest. That’s because Koh Panghan is considered as very touristic and comparable with Koh Samui. Contrary to my expectations I was very impressed when I got there. I only paid 30$ for my flight from Bangkok to Surat Thani. It takes a little longer if you book a flight to Surat Thani instead flying directly to Koh Panghan, but it’s as well much cheaper. You can take a Ferry from Surat Thani to Koh Phangan, which costs only about 10$.
