Thailand’s oldest and largest hospital, founded in 1888 on the Thonburi bank of the Chao Phraya opposite the old city, and Mahidol University’s principal teaching hospital. More than 2,000 beds and every specialty; the public wards run in Thai at public prices, while the Siriraj Piyamaharajkarun wing on the same campus offers private-standard rooms and service.
What it is known for
Size, age and reputation. Siriraj opened in 1888 under King Chulalongkorn and has been the country’s leading hospital ever since — with about 2,145 beds it is the largest in Thailand, and as the Faculty of Medicine Siriraj Hospital of Mahidol University it trains a large share of the nation’s doctors. It occupies a whole riverside district of Bangkok Noi, with its own pier on the Chao Phraya Express Boat line and a medical museum on the campus. For visitors the important detail is that it is two hospitals in one: the public hospital, at public prices and in Thai, and Siriraj Piyamaharajkarun (SiPH), a private-style hospital on the same site geared to paying patients, with its own 24-hour line.
Who it suits
Anyone taken ill or injured on the river, around Khao San Road or in the old city: it is the nearest big hospital to all of them, and the cross-river ferries and express boats reach it faster than a car can. Uninsured travellers who need serious treatment will find it cheap and very competent, at the cost of long queues and Thai-language paperwork. Insured travellers can use SiPH for a more comfortable version of the same medicine, or cross back to the international hospitals on the east bank once they are stable.
Cost and insurance
Two tariffs. The public hospital charges public prices, higher for foreigners than for Thais but still a fraction of a private bill; pay at the cashier and claim afterwards, since insurers rarely direct-bill it. SiPH charges private prices, generally below the international hospitals on the east bank, and is more used to dealing with insurers. Ask for an itemised receipt and an English medical certificate at either, and bring your passport — registration cannot start without it.
Getting there
On the west bank of the Chao Phraya in Bangkok Noi. From the old city take the cross-river ferry from Tha Chang or Tha Phra Chan to Wang Lang, or the Chao Phraya Express Boat to Wang Lang (Siriraj) pier, N10; the hospital gate is at the top of the pier through the market. From Sukhumvit or Silom allow forty minutes to an hour by taxi across the river. Switchboard +66 2 419 7000 (Thai); SiPH +66 2 419 1000 or 1474, 24 hours.
