Hat Sam Roi Yot (Hat Nom Sao)

Hat Sam Roi Yot — also signposted as Hat Nom Sao — is a free public beach on the Gulf of Thailand coast near Sam Roi Yot district, distinct from the fee-charging beaches inside Khao Sam Roi Yot National Park a short drive south. There’s no gate, ranger station, or entrance fee here, and it’s accessible around the clock.

The “Nom Sao” name comes from Koh Nom Sao, a small, rounded island sitting just offshore whose shape gave rise to the nickname (it translates loosely to “young woman’s breast island”). The beach itself is a long, gently curving stretch of sand backed by casuarina trees, with shallow water close to shore that stays calm for most of the year — good for wading and casual swimming rather than serious surf. Local boat operators run short trips out to the island for snorkelling over the fringing reef when the sea is clear, roughly November through April; outside that window, visibility drops and the Gulf’s rainy-season swell can make crossings choppy.

Insider Tip: This is not the same beach as Sam Phraya or Laem Sala — the two developed beaches inside the national park proper, both of which charge the standard 200 THB park entrance fee. If you’re on a budget or just want a quiet swim without paperwork, Hat Sam Roi Yot (Hat Nom Sao) is the free alternative a short drive away.

Wildlife is part of the draw even without entering the park. White-bellied sea eagles are regularly seen working the thermals above the karst outcrops that punctuate this stretch of coast, and the limestone hills characteristic of Sam Roi Yot rise inland behind the beach, hinting at the cave systems (Phraya Nakhon among them) that make the wider national park worth a separate visit. Small seafood stalls set up near the main access points selling grilled fish and som tam, though facilities are basic — don’t expect the amenities of the park’s developed beaches.

Watch out: Because there’s no ranger presence, there are also no lifeguards, marked swimming zones, or rubbish collection points at busy times — bring your own water and be prepared to pack out what you bring in.

Getting here means a short drive off the main coastal road, roughly 40 minutes south of Hua Hin or a similar distance from Prachuap Khiri Khan town. A car or motorbike is the practical option — there’s no regular public transport running directly to the beach access point.
