After about 11 hours of journey, arrived in Baan Rom Mai.
Walked around the Chaweng centres the second day, and rented a motorcycle to Big Buddha wat at the afternoon. It was raining frequently in Samui, and the road flooded frequently as well.
Joined a day trip to Koh Nangyuan and Koh Tao the next day. The beach view of Koh Nangyuan is marvellous, but the underwater view is just normal, not much different from those in the islands of Malaysia.
