<p>Are you going for a college visit? I would advise to fly into Atlanta and rent a car. The drive to Clemson is about 3 - 3.5 hours; however, while around there you could also visit Ga. Tech, UGA, and even Emory if you choose. The only flight you are going to get to Greenville is through a connection(either D.C or Atlanta) and im sure if you contact the college they could tell you if there is some type of shuttle service from Greenville to Clemson. It is really out in the sticks.</p>
<p>You can also fly into Charlotte NC and then on to G'ville or just rent a car in Charlotte and drive. Clemson is a straight shot down I-85 from Charlotte (about 2.5 hours).</p>
