Dodu Haesu Park

A 24-hour jjimjilbang near Jeju Airport on Rainbow Coastal Road. Combines fire kiln (bulgama), jjimjilbang, and sauna facilities. Prices first: jjimjilbang is 14,000 KRW for adults, 11,000 KRW elementary, 9,000 KRW toddlers; sauna only is 10,000 / 7,000 / 5,000 KRW. Late night, jjimjilbang plus bulgama goes to 16,000 KRW while sauna stays at 10,000 KRW. The oxygen capsule sleeping room is 10,000 KRW on top. Open 24 hours year-round, which makes it useful for an awkward gap before a flight, and they'll hold your suitcase. Baths are gender-separated. The hot bath is filled with seawater blended with spring water — the Dodu coast is where spring water meets the sea, which is the whole point of the water here — and there's a cold plunge beside it. Saunas are split into dry sauna and steam room, with a separate bulgama fired with traditional oak charcoal. The jjimjilbang faces the ocean. A lounge looks out over Rainbow Coastal Road and Dodu Port, and you can sleep in the oxygen capsule room. Towels and bath towels, lockers, shampoo, body wash, slippers and hair dryers are all provided, with parking, wi-fi and a kids area. Children are welcome; cash and cards both work. Phone 064-711-1000. Jeju pricing means it costs more than a mainland jjimjilbang, and it fills up when tour traffic peaks.
