To go north in English, you would say "to go north" or "to head north." This phrase comes from the fact that north is one of the four cardinal directions, along with south, east, and west. Here are some example sentences in English and their translations in Chinese:

"We decided to go north on our hiking trip to avoid the crowded trails in the south." (我们决定在徒步旅行中向北走，以避开南部拥挤的小径。)

"The compass on my phone says we need to head north to find the hidden treasure." (我手机上的指南针显示我们需要向北走才能找到隐藏的宝藏。)

"The north wind blew fiercely, making it difficult to walk in that direction." (北风猛烈地吹着，很难朝那个方向走。)
