The A frame is at the end of Bayview Road. You take a left just before the Huron Bay Trading Post and follow the road as far as it is plowed. There is a small parking area there. You will see a yellow gate with a "No Motorized Vehicles" sign. Just follow the road down the hill to the bay.
The other access point is at the public boat launch a little further north. You keep going on the Skanee road until you see the sign for Skanee and the sign for Witz's marina. Take a left there. As you come to the large building on the left there is a road that turns to the left, goes down the hill and follows the bay for maybe a 1/2 mile. The public launch will be on the right side near the end of plowed road.
