Welcome to the start of the Cape Winelands!
You are standing near the first wine farm en route to Stellenbosch, and if you follow along further on the Bottelary Road, you will find many, many wine farms with wonderful wine tastings and adventures to go on. So I hope you do yourself a favour and make a quick stop at one of these farms after you've discovered the cache.
For the cache:
Here onwards the Kuils River flows,
and over it car and man can go.
If you walk towards it with a mansion in your sight,
I will be hiding there just on your right.
Look low, not far, where shadows stay,
a rock keeps secrets close to clay.
Happy caching!
