Directions to the trailhead: From Farmington take route 27 towards Sugarloaf. One mile past the entrance to Sugarloaf at the top of a long hill, Caribou Pond Rd is on your left. This is the first left after Sugarloaf. Follow the dirt logging rd 4.5 miles and park where the AT crosses the road. At 3.8 miles on the logging road you will come to a metal bridge after which the road become much rougher. At 4.0 miles you will come to another bridge that has a steep dropoff on the far side - cars with low clearance will want to be carefull and stay to the left.
You can drive another 1 mile past the AT if you are going to do Redington via the logging road. See Mohamed's site for directions on how to do this via the logging road. (http://home.earthlink.net/~ellozy/reddington.html)
Check out the upcoming trip report for yesterdays (Sunday, August 29, 2005) hike to Reddington for the latest on road and summit conditions. It is definitely the easiest 4K I have done. It will be up sometime today or tomorrow.
Check out the other thread on Redington on Trip report as I just gave an update of the route from South Crocker to Redington, if you choose to go in that way. Might be handy to have my notes.
