Quite an easy cache situated right next to the weir at Katesmill. The cache is just below the level of the weir so watch out that you dont slip on the rocks. It is right next to the water of Leith cache trail so there are lots of other caches to do in the area. It can also be done as part of my A Walk in the Dell multi-cache.
The cache is a small sealed box, hidden near the old sluice gate.

Remember to hide the cache properly afterwards as there are quite a few muggles that come to this area with small childeren and dogs who could accidently find it. Also watch out for the Heron! He (or she 
) can often come and stand in the water near to or on the wier, so keep your cameras ready!

With quite a few muggles around some stealth may be required but it is usually not too bad.
The coordinates for this cache are not 100% accurate as there is quite a lot of tree cover at the cache location. However, once you get to the general area, the clues should help you find it quite easily.
