Start from CR 84 and look for the entrance which has a couple pine log fences in front of it. The first 15 feet are very marshy, but there are usually boards and logs to help give you a surface to bike on. You'll then parallel the road and turn up the first drainage on your left.
The initial climb up this drainage is fairly steep, but you'll cross a primitive bridge and the grade mellows out a bit. After grinding your way up, you'll pop out on a forest service road. Go left to the first 3-way intersection and look for the start of 10cc
