Flinderation Tunnel is located about 15-20 minutes "west" of Clarksburg (Harrison County). The road that you will take is Flinderation Road, of course. Once you get off of Flinderation Road you will cross a bridge and you keep right and then you drive for about 500ft or little more and you will notice in the road that it looks like train tracks ran across the road and you will see a gate on your right hand side in the middle of used to be railroad tracks and thats where you park your car. From the gate to the Tunnel is about 100yds or so back. You will see the "Lake Floyd" sign on your right. Thats the next exit on the left and then Flinderation Road is the "Next" exit on the right.
