Looking for correct Latin translation of "The outdoors beckons"

I have a tile wall hanging that uses the expression "Silva Vocat" which I understand means the forest calls or beckons. I would like the equivalent for the Outdoors or Wilderness, capturing the unspoiled natural world (mountains, streams, etc.). I have found the word Fortis which I think may work for outdoors. I think the translations for wilderness mean things closer to wasteland, which probably then does not work in Latin. Thanks.
