Sea Mark Hotel in Gangneung looks out over both the East Sea and Gyeongpo Lake. The all-white building was the first Korean project designed by Pritzker Prize winner Richard Meier, and guest rooms face the sound of waves and the sunrise. The infinity pool is heated in May as well, and swim caps are required; an indoor pool and hot, cold, wet and dry saunas are also available. The pool is long but narrow.
