I would have to agree with @zebralover10 that Dickinson is a great option. They do have an Outing Club that students can join if they want to take trips during the weekend and hike, swim, ski, kayak, etc. The school is also very environmental and has its own farm and students are more than welcome to volunteer there and get outdoors. I am personally from Boulder, Colorado and while the area is beautiful and the school campus is lovely, it is a very big school and there is not much of a community aspect there. However, if you want to look into Colorado as an option, there is Colorado College which is a LAC in Colorado Springs.
