The KT is rugged and has lots of elevation gains over short distances. Everywhere you hike there are lovely vistas and lots of fossils on the trail snd creek beds. You're never too far from water, although the quality may differ depending on the time of year.
Watch out for ticks. My dogs and I got loads of them in April 2020 from Leota to Spurgeon Hollow. There are road crossings every 5 to 10 miles, so if you run out of something or need to bail you can. The KT asks that you respect leave no trace philosophy, and I felt most hikers did.
There is occasional trail magic but don't depend on it if thru hiking. I have not stayed in any campgrounds near the trail, so I can't review those, but the trailheads all have adequate parking and signage, and I found topo maps online for free.
Let someone know your itinerary, have a means for filtering water, and enjoy!
