Any Khon Kaen residents can tell me of a swimming pool of a decent standard open to the public in Khon Kaen City ? I am here for a week and would like to swim. Thanks

The three large hotels let you pay to use their facilities. If a guest there, obviously, it's free.

Kosa Hotel, Chareon Thani hotel and the Pullman Hotel (formerly Sofitel).

Pulse fitness center also has a pool that you can use on a daily pay basis. It's about 75-100 meters down the soi near Fairy Plaza, on the KFC side.
