If you like the nightlife in Patong Beach, Phuket, enjoy the beach of Chaweng. Chaweng Beach has something for everyone and is one of the most happening places in Koh Samui. Located on the east coast of Koh Samui Island, which attracts many young travelers. I was there in January. Not for clubs, just watching the street.
The area has a variety of hotels, bars, discos, clubs, restaurants and bars to suit all tastes and budgets. As the sun sets, it becomes a city of the party and the main road of Chaweng is one of the best places in Koh Samui for people watching and a great place to shop for beachwear.
Another interesting finding in the island: there are many drug stores and convenience stores 11.07 through the streets of Koh Samui, more than any other provinces in Thailand.
