YoMammy National Park is anational park nestled high in southernmost slopes of the galaxy-famous Skihairy mountain range of Kerona. The park lies to the north Ulence Flats. According to tourist brochures the air in the park is clear, clean, and refreshing. This may actually be due to a weak solution of sulphuric acid in the atmosphere of the mountains. It is often hip-deep with tourists certain times of the year.
