Hua Hin (Thai: หัวหิน, IPA: [hǔə hǐn]) is one of eight districts (amphoe) of Prachuap Khiri Khan province in the northern part of the Malay Peninsula in Thailand.

A group of farmers moved south until they found a small village that had bright white sand and a row of rocks along the beach.

King Prajadhipok (Rama VII) liked the place so much that he built a summer palace there which was later named Klai Kang Won ('far from worries').

From 2004 until 2006 it was the full-time residence of King Bhumibol Adulyadej (Rama IX), until health issues forced him to return to Siriraj Hospital in Bangkok, where medical facilities and physicians were closer at hand.

As of 2019[update], work is underway on the construction of double tracks from Bangkok's Bang Sue Central Station to Chumphon.

The new tracks—due to be completed in 2022—will enable trains to travel the Bangkok–Hua Hin segment in "two to three hours" according to a State Railway of Thailand (SRT) spokesman.

[16] Plans for high-speed rail from Bangkok to Surat Thani which would serve Hua Hin en route, have been shelved due to lack of investor interest.

[18] In November 2018, Hua Hin deputy chief Chareewat Phramanee confirmed the ferry service, suspended due to low tourist numbers during low season, would be up and running again for high season between Hua Hin and Pattaya, a 2.5 hour journey on a catamaran with a maximum capacity of 340.

It includes enlarging the existing passenger terminal, building a second one, expanding hangar space, and widening the runway from 30 to 45 metres.
