I assume you're thinking about doing a one way, 3 day, section of the Sheltowee. I don't have a map in front of me. But, I think you'd be looking at a lil over 10 mi/day (15 mi?). Certainly doable. But, you may not have a lot of extra time to spend at Yahoo Fall, Yahoo Arch, Bark Camp Cascades, Dog Slaughter Falls, etc. I might suggest starting at Yamacraw and also checking out Princess Falls. You could take Trail 612 & 602 past Princess Falls, Markers Arch, Yahoo Arch and Yahoo Falls. Then pick back up the Sheltowee.
FYI - backcountry camping is not allowed within the State Park at Cumberland Falls. There is also a minor re-route of the ST in the State Park; easy enough to figure out if you have a map. We just did a few miles around Cumberland -
HERE. And, backcountry camping in BSF requires a permit ($5) and can be purchased online.
Do you have a map for the Sheltowee? Pretty good maps
HERE.
