valley of the giants access on fraser island

Check the latest conditions report. The northern forest drive was closed as recently as Easter for bridgework. They were looking at bypass. So far as I remember there is only the one road through that area. The camp area is walk in only and is part of the Fraser Island great walk track. See below for links and map.

Last year we met one car driving through a section of Valley of the Giants walk. If you download the Great Walk map (second link under "Getting there and getting around" in the link given above by gbc), you will see a loop track comes into the Valley area from off the Northern Rd. Not sure whether everyone has access to this track, and it's quite narrow.
Along this track you can access the Giant Tallowwood (just off the track) and the Giant Satinay (a 3.5km walk each way), plus just stroll though the Valley of the Giants.
The Valley of the Giants is different from Pile Valley, but whether you would think it worth the trouble is another matter.
