It is possible to drive (carefully) along the trail to within 60 metres of the cache, but it's an easy enjoyable walk from the picnic area car park. The cache location is on the edge of the forest in a rocky area. Care should be taken.
There could be some fluctuation in the coordinates on your GPS, so it may take a few minutes for it to settle.
The cache is a plastic box containing a notebook, pen, giant marble, car, key ring and rubber. There is also a smiley magnet for the FTF.
