A sleepy provincial capital wrapped around three postcard bays — temple-topped mountains, a seafront of seafood restaurants, and an easy hour north of Ban Krut by train.
Find a room before you go.
Prachuap Khiri Khan is the capital of the province Ban Krut belongs to, yet it feels nothing like an administrative town. It sits on a sweep of coast where three bays — Ao Noi, Ao Prachuap and Ao Manao — curve one after another beneath limestone hills, with fishing boats bobbing offshore and a temple perched on the mountain above the harbour. It is one of the prettiest town settings on the whole Gulf coast, and remarkably few foreign visitors ever stop.
From Ban Krut it makes a perfect day out: an hour north on the train, a stroll along the promenade, lunch over the water, the 396 steps up Mirror Mountain if you're feeling energetic, and the night market before the evening train home. Or stay a night — the town is at its best after the day-trippers leave.

The train is the obvious way up: every northbound service from Ban Krut stops in Prachuap Khiri Khan, and the ride takes about an hour along the narrow strip of Thailand between the mountains and the sea. The station is a short walk from the seafront, so no onward transport is needed.
By car it's a straightforward hour and a bit up Phetkasem Road (Highway 4), then a few kilometres east into town. Minivans on the Bangkok–Bang Saphan run also stop in Prachuap — ask for the town centre, not the highway junction.
Cheap third-class local trains cover this hop for a handful of baht; check the return times before you set off, as the evening gap between southbound trains can be long.

396 steps climb through frangipani trees to a small temple with a huge view over all three bays. The resident macaques are bold — carry nothing loose and they'll leave you alone.

The prettiest of the three bays sits inside the Wing 5 air-force base: show ID at the gate and you're in. Clean sand, calm water, casuarina shade and cheap somtam stalls — a Thai family favourite.

Ao Prachuap's seafront is made for slow evenings: fishing boats at anchor, squid drying on racks, and a line of open-air seafood restaurants where dinner comes with the sound of the tide.

Forty-five minutes north, the 'mountain of three hundred peaks' is a coastal park of limestone crags, marshes and empty beaches — easily combined with Prachuap in a day by car.

Inside Khao Sam Roi Yot, a short boat hop and a sweaty half-hour climb lead to a sinkhole cave with a royal pavilion lit by a mid-morning sunbeam — one of Thailand's most photographed sights.

The third-class local from Ban Krut is half the fun: fans whirring, windows open, vendors selling grilled chicken and sticky rice as the coast rolls past. A day return costs less than a coffee.
Prachuap is a working fishing town, and it eats like one. The seafront restaurants along Ao Prachuap serve whatever the boats brought in that morning — grilled prawns, steamed sea bass with lime and chilli, crab fried in yellow curry — at prices that make Hua Hin look expensive.
Look out for the town's dried and grilled squid, a local speciality sold along the promenade, and start the day the Thai way with a bowl of rice soup or a strong coffee in one of the old shophouse cafés near the station.

Every evening the night market near the centre fills with grill smoke and noodle carts — small enough to browse in half an hour, good enough to eat your whole dinner from. It's a genuinely local affair: schoolkids, families, fishermen coming off the boats.
At weekends the seafront adds a walking street with handicrafts, live music and yet more food stalls, and the morning fresh market near the station shows off the day's catch and mountains of fruit from dawn.

Prachuap's hotels are simple, friendly and cheap — this is a town of guesthouses and small seafront hotels rather than resorts. Stay near the promenade and everything is on foot.
Small mid-range hotels along Ao Prachuap give you sunrise over the bay and the seafood restaurants on your doorstep — book a sea-view room, the difference costs pennies.
Wooden shophouse guesthouses in the streets behind the promenade are the cheapest sleep in town, run by families who'll lend you a bicycle and draw you a map.
Inside the air-force base, the Wing 5 area has simple accommodation right on the best beach — quiet, safe and wonderfully odd, though you'll want wheels for dinner in town.
