If you know where the waterfall overlook is (on the columbia trail side )
there is a steel pipe fence that is about 20 ft long you would go over that small hill and on the left will see the falls and on the right is a down hill trail that you would take , follow trail to end go strait to pavement make a quick left and ride over bridge follow trail and keep chain link fence on RIGHT , go up small climb and you will pop out at river road and the bottom of nassau rd just climb nassau and your there GOOD LUCK !
