Facilities for travellers with disabilities in Seoul and some other cities are far from perfect but are improving. Most Seoul subway stations have stair lifts, elevators and toilets with wheelchair access and handrails, while buses have ramps to aid wheelchair access. Tourist attractions, especially government-run ones, offer generous discounts or even free entry for people with disabilities and a helper. There are also some hotels with accessible rooms.
