Prachuap Khiri Khan Province Guide: History, Towns and Local Products
Prachuap Khiri Khan is where Thailand is at its narrowest: in places, only about a dozen kilometres separate the Gulf of Thailand from the border with Myanmar. Into that strip fit the royal resort of Hua Hin, the limestone peaks of Khao Sam Roi Yot and a string of quiet fishing bays.
This guide explains why kings kept returning to this coast, looks at its eight districts and lists the pineapples, coconuts and seafood the province sells. If you run a small business here, you will see how to put your products in front of new buyers.
Prachuap Khiri Khan
Royal Beaches, Limestone Peaks and Pineapples
A long, thin province between the Gulf of Thailand and the Burmese border, where Thai kings came for sea air and for science.

Why Prachuap Khiri Khan became a royal coast
In August 1868 King Mongkut travelled to Wakor, south of Prachuap town, to observe a total solar eclipse he had predicted himself. The event is remembered as the start of modern science in Thailand, and 18 August is now National Science Day.
The railway reached Hua Hin in 1911 and turned a fishing village into the country's first beach resort. King Prajadhipok built Klai Kangwon Palace there in the late 1920s, and the royal family has spent time there ever since. Further south, Ao Manao recalls 8 December 1941, when Thai airmen fought the Japanese landing on the beach.

Planning a visit: dates and seasons
Prachuap Khiri Khan's year is shaped by its coast and its royal dates. Here is what to plan for.
Shopping local in Prachuap Khiri Khan
The OTOP scheme gives every product a home sub-district, and in Prachuap Khiri Khan the land between the hills and the sea is given over to pineapples and coconuts, with canneries along the coastal plain.
The fishing towns dry squid, fish and shrimp, and Hua Hin's markets sell these alongside coconut sweets and fruit from the province's farms.
The carousel near the top updates itself with listings from Prachuap Khiri Khan. For sellers, the only cost is the annual shop plan.
Short on time? Hua Hin station, then the beach. Love the outdoors? The climb to Phraya Nakhon Cave. Into history? Wakor and the eclipse memorial. Buying local? Dried squid and a fresh pineapple.
