About Rayong

Rayong is an eastern Gulf-coast province with mainland towns, beaches, agricultural areas and offshore islands. The provincial city, Ban Phe, the Laem Mae Phim area and Ko Samet serve different purposes for a visitor and should not be treated as one beach resort.

Ko Samet is the best-known island destination, with beaches including Hat Sai Kaeo and quieter bays. Mainland options include coastal viewpoints around Laem Mae Phim, the mangrove landscape of Thung Prong Thong and local seafood markets. Fruit-growing is another part of provincial identity; harvest events and orchard visits depend on the current season and programme.

If travelling to Ko Samet, confirm the mainland pier and the exact island landing with your accommodation or operator. Mainland accommodation does not remove the need for a boat transfer, and journeys between coastal areas require realistic road time. Check sea forecasts, beach flags and current park arrangements before marine trips. Do not assume calm water or unrestricted access from a promotional description, and confirm seasonal events before planning around them.

Rayong Province covers 3,552.00 square kilometres and had 8 districts, 58 subdistricts and 441 villages at 31 December 2024. Its 2024 registered population was 782,171; this is a whole-province civil-registration count, distinct from the capital city or an estimate of visitors.

November to February generally offers cooler conditions for outdoor visits. The hotter period and the rains bring different travel considerations, with rain usually increasing from around May to October; check current forecasts for your route.
