How to say "mountains" in Japanese

• 山岳さんがくJLPT N1approx.Common
  nounMountains as a collective geographic feature — a chain or range of peaks rather than a single mountain; the natural choice when describing mountainous terrain, as in geography or landscape description.
  ついに病気びょうきで疲つかれた男おとこたちは彼かれが待まっている山岳さんがく都市としに到着とうちゃくした。↗

  Finally, the sick, tired men reached the mountain town where he was waiting.
• 山岳地さんがくち
  nounReally means mountain land — an area of mountainous terrain — so choose it when 'mountains' refers to the land or region itself; it is less common and not the default word for mountains in general.
  この犬いぬは山岳さんがく地ちで人ひとを救助きゅうじょするよう訓練くんれんされています。↗

  This dog is trained to save people in the mountains.

Use 山岳 for mountains as a collective geographic feature or chain, and 山岳地 when you mean mountainous land or a mountain region; the latter is less common and narrower, so 山岳 is usually the safer pick.
