Koh Samet has a lively nightlife scene along a sizable stretch of Sai Kaew and Ao Phai. Catering for backpackers.On the beach has a lot of bars and restaurants in terms of general ambience, music and drinks menu. Most have cushioned loungers and low tables lit by kerosene lamps set up right on the sand. And since the competition is stiff, each seems to offer either a happy hour deal of some sort or a kind of drinking game where you are rewarded with a couple of free drinks.
The atmosphere here is totally relaxed and casual. No dressing up is necessary anywhere on the entire island. So just chill out and drink it all.
