Krabi is located 814 kilometres from Bangkok, covering an area of 4,708 square kilometres. From archaeological discoveries, it is believed that Krabi was one of the oldest communities in Thailand dating from the prehistoric period. It is also believed that Krabi was once the town of Ban Thai Samo, one of 12 royal cities that used a monkey as the town symbol. Krabi was a dependency town of the Nakhon Si Thammarat Kingdom. Another legend indicates that the town may have taken its name after the meaning of Krabi, which means sword. This may have stemmed from a legend that says an ancient sword was unearthed prior to the city’s founding. Later, the sword became a symbol of Krabi.

The province consists of mountains, hills, plains, and mangrove forests, including more than 130 large and small islands. Krabi town has a 5-metre-long river, which flows through town and ends at the Andaman Sea in Tambon Pak Nam.

There are several canals in Krabi including Khlong Pakasai, Khlong Krabi Yai and Khlong Krabi Noi, all of them originate from Phanom Bencha mountain range, the highest mountain range in Krabi.
