Park at the waypoint co-ordinates. (No parking at the cache)
You will find the co-ordinates of the cache at the waypoint which is 2 ml - you have to find it to work out the shape.
The cache is a 500 ml screw top plastic jar.
After finding this cache, you might like to do Questioning Our Sanity - GC18A9N (http://www.geocaching.com/seek/cache_details.aspx?wp=GC18A9N) Just go a few metres further along the road, then take the Second path up the hill. This goes right to it, although it is quite steep.
