We perceive the gross or seen world through the five physical senses (i.e. smell, taste, sight, touch and sound), our mind (our feelings), and our intellect (decision making capacity). When it comes to the unseen world or the subtle-world, we perceive it through the five subtle-senses, the subtle-mind and the subtle-intellect – this is what is known as our sixth sense.
The cache cannot be that easy, you will need your Sixth Sense for this one.

The cache is placed in the Bluff Nature Reserve. You will need to park in the normal Bluff Nature Reserve parking. Once you have paid, parked, then ask the the ranger on duty about the park over the road. Tell him that you have heard of the lovely trails there, and he will produce a key. The key gets you into the gate.
The rest is up to you, enjoy the trail and the duiker if you are quiet.
