The cache is a orange cylinder box that says 'citric acid' on it (sorry! I could'nt find anything else), BRING YOUR OWN PEN!!!! It is situated on the twinfalls loop near a old graveyard and the Yellowwood forest. Walk +-1 km. If you are not happy with my directions then by all means ask the reception for a Guide Book or direction Guide.
Directions
Go past the Oaks Supermarket and through the boom gate at the entrance and turn left.
Carry on down this lane till you come to a fork in the road, at the fork turn right.
About 100m ahead you will see an Adventure Area, Park on the right by the picnic tables under the trees.
Walk up the Tar road, passing a little dam on your right. Carry on further.
You will come to a four way intersection where you will turn right onto a dirt road.
Walk down the dirt road, you will cross over a small cement bridge over a stream where the path will then take a sharp right. After the cement bridge DO NOT follow the path RIGHT, instead turn LEFT onto a single track path.
At the fork take the bottom path (left) as this will give you the better views of the waterfalls on the way.
The cache is loccated at the second waterfall.
