<p>Which US college has the largest campus by physical acreage?</p>
<p>And a related question: Which campus has the least population density? That is, when you take total enrollment (grad and undergrad) divided by campus size, which college would have the largest number?</p>
<p>Berry is huge, but so is the USAFA because of their landing grounds. Sewanee (University of the South), Stanford and Duke are also huge. The University of Michigan-Ann arbor has 3,200 acres, but an additional 18,000 acres in arboreta and research stations. Altogether, Michigan's acreage totals close to 21,000 acres, making it the second largest campus in the nation.</p>
<p>Sewanee: The University of the South clocks in at 10,000 acres for about 1,300 students. The school owns the mountain. There are lakes (plural), rock climbing venues, trails, etc.</p>
