After you have found the cache you can carry on walking over the rocks and beach, under the cliff top and find several caves.
If the tide is in park at S36 37.040 and E174 48.218
You may feel that you are heading nowhere, but just keep following your nose and the sign posts and eventually you will drop down to the "Tradesmans Entrance".
Take care when walking as it can get a bit slippery both ways.
The cache is a round plastic container with a green lid containing - 2 American coins, 2 American football cards, 6 golf tees, 4 paper clips, toy car, cork, pencil sharpener and the Travel Bug Speedy 808 that came from Australia.
