What are the alcohol-free options in Koh Samui?

That's good, to be honest. April is the hottest month of the year and not drinking alcohol is a good idea, as it would really dehydrate you. You might want to stick to water and the occasional fruit smoothie.

A 0% beer from Heineken can be a suitable alternative. Its taste is remarkably similar to regular beer, making it difficult to distinguish. Upscale bars often offer a variety of mocktails, but some are essentially just tonics with a squeeze of lime, priced similarly to cocktails.
