在城市里呆久了偶尔接触一下大自然，去爬爬山不失为一种慢节奏的放松活动但其实这种悠闲的运动并不是climb mountains。如果是去珠穆朗玛峰这种专业登山的类型，这时是需要准备很多装备和工具等等，我们就可以使用climb mountains较为合适。
而在我们日常生活中作为娱乐而去的“爬山”其实应该是go hiking
现在很多人喜欢放假的时候去徒步一下，大家平时所说的那些“爬(小)山”，就是一些小山坡，小山丘这类型的简单走一走。这时使用go hiking(徒步或远足)或者go hikwaking(丘林地带的远足旅行)比较正确。
例：If the weather's fine, we'll go hiking this weekend. 如果天气好，我们这个周末就去远足。
