Sangwan Beach of Koh Larn is a very small beach. There are all the usual things to do and there are plenty of choices for food and drink. In this photo you may be able to see the dome shaped canvas covered bungalows that you can rent. For such a small beach it really has all you need. You get to this beach from the Tawaen Beach pier, while walking on the walkway towards Tawaen Beach you will come to a wooden bridge to the right, there are signs there also to guide you.
