Rayong and Koh Samet, Thailand. 3 major hospitals, 1 public, 2 private.
Three hospitals, all of them in Rayong city — one public, two private — with addresses, phone numbers and maps, a plain guide to which one to head for, and what getting a casualty off Koh Samet actually involves.
If you only read one thing
In a life-or-death emergency, the nearest emergency room of the three, or 1669 — and from Koh Samet say which beach you are on, so the crew can plan the boat.
Rayong is a working province with a holiday coast attached: a provincial capital of shophouses and seafood markets, the petrochemical estates of Map Ta Phut to the west of it, the long sweep of Mae Ramphueng beach to the east, and at the end of that beach the fishing town and ferry port of Ban Phe. About six kilometres offshore lies Koh Samet, roughly three hours from Bangkok and busy every weekend. The medicine is all in the city. There is no hospital at Ban Phe, none at Mae Ramphueng and none on the island — Koh Samet has a small government health centre near Na Dan pier and nothing larger.
This page lists the three hospitals a visitor would actually use, all of them in Rayong city and within about fifteen minutes of one another: the 555-bed public referral hospital on Sukhumvit Road, the private Bangkok Hospital Rayong on the western edge of town, and Chularat Rayong, a smaller private hospital a few streets from the public one. Every name opens a full page on that hospital. Details were checked against each hospital’s own website in September 2026; switchboards do change, so if a number fails, call 1669.

Read the full pageFor a serious emergency with insurance, or anything complicated, go to Bangkok Hospital Rayong on the west side of the city: it is the province’s BDMS hospital, its accident and emergency centre is open around the clock, and English is spoken. Without insurance, or for anything serious that needs beds and specialists rather than a comfortable room, Rayong Hospital on Sukhumvit Road is the 555-bed public referral hospital for the whole province and by a wide margin the cheapest real care on this coast. For a minor illness or injury in the centre — a stomach upset, an infected cut, a fever that will not shift — Chularat Rayong Hospital on Chan Udom Road is a small private hospital a few streets away that will see you faster than the public queue. In a genuine life-or-death emergency go to the nearest emergency room of the three, or call 1669 and let the ambulance crew decide.
Three tiers, and the gaps between them are wide. Rayong Hospital charges foreigners more than Thai citizens but still very little by Western standards: a consultation, tests and medicine usually comes to less than a night in a mid-range beach hotel, and even an admission is affordable. Chularat Rayong sits in the middle — several times the public rate for the same outpatient visit, with a deposit expected on admission, in exchange for being seen quickly and in a quieter building. Bangkok Hospital Rayong is priced like the group’s hospitals in Bangkok and Pattaya, which is to say like a Western private hospital: with insurance it is the obvious choice, without it a serious admission runs into the hundreds of thousands of baht. Ask for a written estimate before any procedure at any of the three.
The two private hospitals are used to travel insurance and will contact your insurer for a guarantee of payment — but only where the insurer has an agreement with them, and usually only for an admission; outpatient visits are almost always pay-and-claim. If there is time, ring the assistance number on your policy first: it can name the hospital it prefers and open the claim before you arrive. Take your passport, your policy number and any medication you are on, and after a road accident take the rental agreement and your driving licence too — Thailand’s compulsory motor insurance covers some injury costs, but only for a licensed rider, and a great many travel policies exclude motorbikes and quad bikes altogether. Ask for an itemised receipt and an English-language medical certificate before you leave; the public hospital will write both if you ask, in Thai unless you say otherwise.
All three hospitals are in Rayong city, strung along or just off Sukhumvit Road, and a taxi crosses between them in ten to fifteen minutes. The national ambulance number is 1669: it is free, it answers around the clock, and it takes you to the nearest appropriate hospital, which for an uninsured patient usually means the public one. Bangkok Hospital Rayong runs its own ambulances and answers on +66 38 921 921, or 1719 from a Thai phone. Ride-hailing works inside the city but thins out along the coast road towards Ban Phe, so from a beach hotel it is quicker to have the front desk call a car than to wait for an app. Songthaews run the coast road cheaply and slowly, and a motorbike taxi is no place for an injury.
Koh Samet has no hospital. What it has is a small government health centre near Na Dan pier for everyday complaints and first aid, and a private clinic or two behind the beaches. Anything more leaves by boat. The ferries cross to Ban Phe in thirty to forty minutes, run through the day and stop in the early evening; after that it is a chartered speedboat, quicker but many times the fare. From Ban Phe it is another half hour by road to Rayong Hospital, forty to Bangkok Hospital Rayong: a bad injury on a Samet beach is two hours from an emergency room in daylight, longer after dark. So decide before the last ferry, not in the morning. Most of what makes the crossing is predictable: rented scooters and quad bikes on narrow, unlit tracks, no helmets, often after a beach bar. Call 1669 from the island too — it is free, and the crew arranges the boat.
For sunburn, an upset stomach, a rash or an infected scrape you do not need a hospital at all. Thai pharmacies sell most everyday medicines over the counter, including antibiotics and painkillers that would need a prescription at home, and a licensed pharmacist — look for the framed certificate — will usually speak enough English to advise. In Rayong city the chains in the malls are the easy option and the independent shops along Sukhumvit Road stay open late; Ban Phe has several near the piers, and Koh Samet a couple near Na Dan and the main beaches, at island prices. Cuts heal slowly in the humidity, so clean them and keep them dry. A jellyfish sting gets vinegar first and a doctor if it is more than a nuisance, and a fever lasting more than a couple of days needs a blood test for dengue, which is present on this coast, not a pharmacy.
