Interest: 4/10 Warnings: National Parks and Wildlife are renovating these bunkers so nightime would be the time to go. Equipment: At least one torch each with good batteries. Description:Drive down Chowder Bay Road and you will see what looks like a storm water drain on your left below the level of the road. This is one entrance to the bunker but you cannot enter from here. Jump on the roof of the bunker and follow in south. At the south end there is another doorway. This door has a square hole in it. This will provide you with access. Lean through the hole and grab the metal fencing on the back of the door and pull yourself through. On the ground you will notice the rail tracks where they used to cart stock into the bunker. After the door you are in the main corridor. This goes through to the north entrance in which you could not get through. To the left and right of the corridor are lots of rooms. These rooms held amunition as can be seen by the writting written above the doorway "20,000 rnds". EOF.
