Oreads

In Greek Mythology, the Oreads, or Orestiads, were the nymphs that inhabit mountains, valleys, and ravines, and were sometimes associated with the hunter-goddess Artemis. They were often classified from where they dwelled; for example, the Idaeae lived in Mt. Ida, while the Peliades were from Mt. Pelion.

Echo was an Oread.
