Bangtao Beach spans 6 km in length, making it one of Phuket's longest beaches. For the most part, it's pretty deserted – hotels mostly occupy its southern end, while the northern end is generally very quiet and peaceful. Only a few small beach bars are dotted along its length.
The sea is flat, calm and clear from November to April. The waves can get a little rough between May and October, so take note of red flags on the coastline. Bangtao Beach attracts those looking to leave everything behind and do nothing more taxing than reading a book.
The exception to this rule is if you're at the southern end of the beach. There are several beachfront hotels and beach clubs, resulting in a very lively atmosphere in the evening. However, Bangtao remains one of the most family-friendly beaches in Phuket.
