Bad Branch Falls is in Rabun County north of Tallulah Falls. Take 441 North from Tallulah Falls about 2 miles to Old 441 (there should be a sign for the Raburn Beach Rec. Area) and make a left.
Stay on Old 441 about 2.5 miles to Lake Rabun Road (it will be a mjor intersection and you are coming from one of the Forks in the road). Stay on Lake Raburn Road about 6 miles until you come up on the Lake Seed Damn Bridge on your left. You will see it as the road to the bridge will drop off to your left. Take that one lane bridge until and go a few hundred yards the road will make a right (a unpaved road will be in front of you), stay to the right on the paved road and proceed about .25 miles and look for Crow Creek Road on your right. Take Crow Creek Road about 2.9 miles and the unmarked trail will be on your left. Don't worry if you don't see it, if you get to the Georgia Power Rec and Day use area you went a few hundred yards too far.

This is a fairly easy 5 minute walk and the falls is very accessible. Well worth the visit!

I rate this falls a 7-8 and access difficulty is a 2.
