Description:

The fourth free-standing pillar. Awkward to access. Either use a boat or, if water level is not too high, it may be possible to rap from steel bridge and cross a strip of land to pillar. Exit by ascending rap line or tyrolean from pillar top to bridge. There is also a rusty cable that runs between pillar one and pillar four. You may be able to shimmy along this, but this hasn't been tested.
