I've got 4 days for a backpacking trip, and I'll probably return to GSMNP. I've only been to 3 areas thus far: cosby, cataloochie valley, and big creek. I was a huge fan of cosby and big creek (big creek has way too many creek crossings though), and didnt dig cataloochie so much because horses have made those trails terrible. What is another essential area to hike? i wanted to hike up smokemont up to Charlie's Bunion, but there are only shelters, and I prefer to pitch in a tent.
