Krabi Province ; Krabi (Thai: กระบี่) is a town (thesaban mueang) on the west coast of southern Thailand at the mouth of the Krabi River into the Andaman Sea. As of 2005 the town has a population of 24,986. The town is the capital of Krabi Province and Krabi district. Tourism has become the most important feature of Krabi today. With its beautiful beaches and unspoiled islands, Krabi is now one of the most famous tourist destinations in Thailand. Krabi is a southern province on Thailand's Andaman seaboard with perhaps[vague] the country's oldest history of continued settlement. After dating stone tools, ancient colored pictures, beads, pottery and skeletal remains found in the province's many cliffs and caves, it is thought[by whom?] that Krabi has been home to homo sapiens since the period 25,000 - 35,000 B.C. In recorded times it was called the 'Ban Thai Samor', and was one of twelve towns that used, before people were widely literate, the monkey for their standard. At that time, c. 1200 A.D., Krabi was tributary to the Kingdom of Ligor, a city on the Kra Peninsula's east coast better known today as Nakhon Si Thammarat. Krabi is now a top destination for beach and islands lovers. Much of the province has been the seat of several national parks. The topmost destinations are Hat Noppharat Thara, Ao Nang, Railay, Ko Phi Phi National Park. Yet over 80 smaller islands such as Lanta islands,or Koh Lanta, Phi Phi islands - made famous as the ideal location for adventurers, yachtsmen, scuba-divers, snorkelers and day-trippers from Phuket. The Ko Lanta National Park, also in Krabi province, includes several coral-fringed islands with well-known diving sites. The largest island, Ko Lanta Yai, is the site of park headquarters, and is also home to Chao Le, or sea gypsies who sustain themselves largely through fishing. The islands are best visited during the non-monsoon months of October through April. Kayaking, sailing, birdwatching, snorkeling are also among top activities. In the interior, two predominantly mainland national parks, Khao Phanom Bencha and Than Bokk-horani, offer inland scenic attractions including waterfalls and caves, and opportunities for trekking, birdwatching and eco-tours.
