Jjimjilbang in Jeju — Korean Sauna & Spa Guide

Jjimjilbang is a quintessential Korean experience — a public sauna, spa, and communal resting space all in one. Entry costs ₩10,000–15,000 and includes access to heated rooms, hot baths, and a lounge area where you can sleep overnight. Most are open 24 hours. Men and women use separate bathing areas but share common spaces. Bring nothing — towel, shorts, and t-shirt are provided.
