Get yourself to Key Bridge. If coming from the South, just stay on Key Rd until you can't drive straight anymore. If you come to a four way, go straight. The road will change names to Millway Rd sometime after you pass Pete's store at the 378 intersection.
Just go straight at every intersection until you get to one in which you can't go straight. Eventually you will cross SC221/10 and just drive straight. You will also cross a RR track when you cross 221/10. Keep going straight. You will come to an intersection where you have to go left or right. There will be a large ante-bellum home right in front of you and a cemetary over your left shoulder. Go right.
In about a mile or so on the right will be the Fell Hunt Camp. Park there. I think there is a $3 fee to park at Fell (like Lick Fork).
The write up about Fell Hunt Camp on that site was hilarious. Obviously written by someone whose job was to write about a bunch of places one has never been. It mentions a bunch of stuff to do....none of which is a good reason to camp at Fell. And then says nothing about the trail that Fell is on! To this reader, it was hilarious.
Good map. The right turn at the large southern home is onto Cedar Springs Rd. If you get on Key Rd, and never turn until you will hit a large white home if you don't turn (right), you will get there.
This is a great trail. This will be a great ride if it doesn't rain all week.
