Assess to those crags is secure and stable. The KZN MCSA site is not too out of date, as none of the crags have moved riecently.
If you want to go to the Wave or Rasta cave, it is better to stay in a biggish group. ie 6 or more people, and contact the reserve the day before to organise the guard. (at R15 an hour). Magnetic wall is fine without the guard.
Montaseel is fine but don't leave stuff unnattended.
Kloof gorge is fine. For the canyon, park on the verge and walk through the Pysio's property. They don't mind but be nice to them. They don't have to let us through. Always sign in and out of the climbers register at the picnic site for climbing anywere in Kloof Gorge. Official entrance fee the the Gorge is R10 pp.
I haven't been to Winston Park reicently but last time I went, about 18 months ago, it was okey. Just there is a wall you have to jump over to get into the vacant lot. A house has been built on one half of it but the owner seams friendly. His name is \"Vino\" (not sure of spelling) be nice to him.
Notwithstanding the above, as always at any crag in South Africa, there is always a chance of getting mugged, so leave non essential valuables at home, stay in big groups and don't be an idiot.
For more details or help give me a shout.
