The hot spring is OK, the children are very happy. The water park is also warm water, so let the children fling in it with confidence. The big slides have to lie down and slide, sit up when you are about to the end, otherwise you will hit your head or arm at the beginning. I didn't experience it outdoors, I don't know how. I really want to soak in the hot springs and face the sea. It is recommended to bring your own lunch. This is not like other hot springs with buffets. They only provide simple meals such as burger egg stew beef noodle soup fritters. The variety is very limited.
