Great Smoky Mountains trip

Going on a trip that will take me through Great Smokies. Trying to figure out how many days I should set aside, currently looking at two or possibly three days. It’s just an incidental part of the trip but I’d like to make the most of what I can dedicate to it.

I'm mostly just trying to get some recommendations on favorite trails for hiking, I have no issue with long hikes although I am trying to get a solid experience of the park in with whatever time I allot. Plan is to get up early each day and hike all day, so should be able to get some good miles in.

Also planning on staying in or around Cherokee, since I’ll be approaching the park from the south, possibly migrating up to stay in the Gatlinburg area on the last day since the return home is northward.

Just trying to get overall advice and recommendations for hikes and whatnot, thanks everyone
