The authorities that be at the Celebrity Hotel in Gulou have decreed their outdoor roof-top swimming pool shall close in mid September. Utter madness. Nevertheless, the pool makes for a pleasant getaway from the crowds at many other large pools in the city. Choose a value card; ¥480 for 10 swims, ¥680 for 20 swims, ¥880 for 30 swims or the bargain basement ¥1080 for 50 swims. A little shop is on hand selling cold soft drinks, swim aids etc., while the pool also offers a segregated lane for doing lengths, although given the size of the pool this may be better termed “breadths”.
