<p>Sewanee certainly comes to mind; relatively few colleges combine a great education with such a beautiful setting. Perhaps Warren Wilson as well, though I think UNCA has a much more convenient location. </p>
<p>Many of the Maine LACs (Bowdoin, Colby, Bates, the College of the Atlantic, etc.) might fit, depending on your size and selectivity constraints. Several schools in the Pacific Northwest - Whitman, UPS, Evergreen State, Linfield, Lewis & Clark, Reed, Willamette, etc. - might also work. Although not all of them are rural, most of them have very strong outdoors programs and decent environmental science offerings. </p>
<p>For a larger option, Clemson comes to mind. It’s of medium size for a university and is good about offering in-state tuition to strong OOS applicants.</p>
