There are eight different onsen areas and almost 100 onsens within the city that offer hot baths, sand baths, steam baths, and steam-dining. They range in quality, size, and price from cheap, small, rundown shacks to grand halls with waterfalls and laser light shows. Tourists from all over the world come to the city just for the onsen, and can be seen throughout the city year round. If you are of the mind to, you can participate in the spa passport challenge to collect stamps by visiting the different approved onsens in town. As you reach different levels, you can claim different towels to proclaim your knowledge of and enthusiasm for Beppu onsen.
