1、plan to travel 或者plan to take a trip都可以
2、小镇不用little town而应该用small town，I will visit some small towns.
3、I want to go to some peaceful places where I can see some animals and back to the nature.
望采纳，谢谢，杭州凤起路精锐1对1欢迎来看看。

planning to take a trip 对的
maybe some small town 这样比较顺口一些
I want to go somewhere peaceful
