Gwangalli Aqua Palace Jjimjilbang is a sauna on floors 4 to 6 and 8 to 9 of Hotel Aqua Palace in the center of Gwangalli, and it uses hot spring water. Full-length windows look out onto the sunrise and the Gwangalli view. On Saturdays, a drone show is visible from the sky observatory. Black dust remains on the floor, so the hygiene condition is poor.
