Phuket is one of the many party sides of Thailand. You can travel here from the capital of Bangkok easily by plane or overnight bus. Phuket has two sides, the party beach life of Patong and the historical, more cultured side of Phuket Old Town.
If you want a taste of the beach life without the nightlife side of Patong while in Phuket there’s still a number of great locations including the incredibly tranquil Sirinat National Park or even Kata and Karon beach.
If big cities like Bangkok aren’t your thing then you could easily spend ten nights (or more) on the laid back south of the island experiencing the likes of Phuket, Krabi and Phi Phi Island.
