The famous buckets of Phangan are a great way to get into the right party mood fast and effectively. They are normally a mix of Thai whisky and Red Bull, but other mixes like Vodka and Red Bull are by now on offer.
The buckets come with the closed bottles, so you can create your own mix according to the alcohol content you wish to achieve -- as such from social drinking in groups friends to all-out debauchery are possible options.
Phangan bars On the night of the full moon, every restaurant, bar and store turns itself into a bar that will sell you buckets stuffed full of alcohol in many varieties. The four best bars (which are also the loudest) are The Cactus Club, Drop In Club, Vinyl, and Zoom, all located in Hat Rin.
