If Wolves are your thing, then this place is very interesting. You will listen to a 10 minute CD about wolves and their habitat and movements and then be taken on a small tour of the place where you get to see up to 8 different types of wolves (in South Africa).
There is a small visitors center and the entire tour is R25. They live off donations and its not a well known place but very interesting.
The cache is hidden nearby the visitors center.
Please park at the given co-ords and walk the "walk" to the entrance. Its quite a walk and hence the 1.5 rating !!
Small note on cache maintenance: Property owners know of the cache and will help maintain it.
