- Jeju is like being transported to another world. Don't plan for a couple of hours, spend the day here. The price is super reasonable for the experience ($30 for the day + additional fees for services). Sweat it out in the crystal/mineral sauna rooms, take a dip in the whirlpools and hyrdrotherapy pools, enjoy some fried rice (an admittedly odd juxtaposition to all the wellness stuff, but also tasty!). Getting an additional service is worthwhile! Be brave and get a full body scrub, and you'll feel cleaner than the day you emerged from the womb! You'll leave so calm you'll find the outside world jarring! Bring a friend, but note that some areas are separated by gender.
