Hat Sai Ri is one of Chumphon's better-known beaches, a long Gulf coast stretch tied to the shrine and memorial of Prince Chumphon, a key figure in the history of the modern Thai navy. That mix of beach, local pilgrimage and naval memory gives it more interest than a simple strip of sand.
The beach is relaxed rather than resort-heavy, and it works well for travellers breaking the journey between Bangkok, southern Thailand and the islands. Come for a walk, seafood and sea breeze; stay longer if you like quiet coastal towns more than polished beach resorts.
