Prachuap Khiri Khan is a quiet coastal province on the Gulf of Thailand, squeezed between limestone mountains and the sea at the country's narrowest point. The provincial capital of the same name is a low-key Thai town with a stunning bay, a hilltop temple with panoramic views, and none of the tourist crowds you will find further north.
The province stretches along what Thais call the Sunrise Coast. Most visitors head straight to Hua Hin or Pranburi, but the capital itself rewards a stop — especially if you are beach-hopping southward. The bay at Ao Manao, inside a military base, is one of the prettiest in the region, backed by dramatic karst peaks. Khao Chong Krachok, the "Mirror Mountain" temple in town, offers views over the bay and the fishing boats below.
Further south, Bang Saphan and Koh Talu Island offer quieter beaches. The next major town down the coast is Chumphon, the jumping-off point for boats to Koh Tao, Koh Phangan, and Koh Samui. Just north of the province, Cha Am sits above Hua Hin.
North of town in Kui Buri, Kui Buri National Park protects one of Thailand's healthiest wild elephant populations, visible on guided evening drives. Accommodation in Prachuap Khiri Khan town is limited compared to Hua Hin, which is part of the charm — this is an off-the-beaten-track stop where you eat at the night market alongside locals rather than tourists.
