Put a Smile in your Heart!
The barren lands of the Castle Peak Range have many rocks, some of which resemble things, such as the bread rock which closely resembles a huge piece of bread with some slices cut off of it, a rock that looks a bit like a heart, and one that has a big smile on it. This cache links the latter two, hoping that when you find it, you'll have a smile in your heart as well!
The heart rock you can find along the trail between Bread Rock and Moon Gully, via the listed coordinates of this cache. Either direction will work. You may consider a detour via Castle Peak Range.
On the left hand side of the rock (as seen from the trail - blacked out on the attached photo), something is written in Chinese. How many characters do you see there? This is N. Now put this number in the following two formulas for bearing and distance (the * means multiplication).
Bearing: 83.6 * N °.
Distance: 293 * N meter.
Plot this distance and bearing from the location of the Heart Rock. Go to this point, here you can see a rock with a big smiling face on it. And why is that rock smiling you think? Well, because of course it's got a cache for you at it's foot of course! It's that easy. Or is it?
Have fun! And keep on smiling.
About the area.
Note that the area is barren and highly exposed. Bring enough water, and then some. Also bring enough food, and protection against the weather - sunglasses are highly recommended in sunny weather as the exposed soil is very light in colour.
The trails here are mostly unmaintained, rough and gravelly. Wear proper footwear and be careful hiking here. Bring a good map, there are many trails and it's easy to get lost.
