After overeating in Korea, I wanted to exercise by running and then relax in a hot spring. I stumbled upon Jagalchi Seawater Hot Spring and booked the gym + hot spring package! On the first floor, I showed the staff my QR code for the reservation. After confirming my name, they gave me a shoe locker number. I went up to the second floor, found the corresponding shoe locker, put my shoes inside, and then walked further in to find the clothes locker, which had the same number as the shoe locker. On the second floor, I changed into my workout clothes and headed to the gym on the 4th floor to exercise! (Since I booked the gym package, they provided workout clothes.) After exercising, I returned to the second floor, took off my workout clothes, and put them into the towel recycling bag. Then, I walked up the stairs to the third floor, which is the hot spring area. You need to bring your own shower gel and shampoo. If you don't have toiletries, they are sold on the first floor, cash only. Soaking in the hot spring after a workout is incredibly comfortable! I'm very grateful for a place like this that allows me to use a gym during my food-filled travels in Korea. I came here for two consecutive days!!!
