Only place to get launch/ramp permit that will be convenient for you is at the DNR office at the main gate. I assume you are getting off at the Tell City/French Lick exit. Follow 145 North until you see 164 turn to the left, you will see the lake start as soon as you need to turn. Take 164 up the hill a mile or so and turn right onto 221/27. You will see the DNR office on your right before going through the gates into the park. You can also get your fishing license there, but if you need bait I suggest Poor Boys on 145, before you get to the lake. You can't miss them on the right hand side of the road.
