@CraigW – that was a weird one. The locked gates didn’t stop access along the SSW as you could still get to it from the Lynwilg and Dalraddy entrances. It just stopped access to the estate via the three roads. We chatted to one of the estate guys when we were out for a walk and he said that the gates had been put in place because there were too many cyclists, they were ignoring the estate traffic, and that some of them were on “guided” rides. The whole affair was strange at the time. The (expensive) gates are still there, permanently open.
I suspect that if Povlsen/Wild Land Scotland had owned the estate earlier, that bit of the SSW would never have been built and we’d all be happily using the existing estate track.
