Summer is here so it’s time to get the mountain bike out. Started from Greystone and slogged my way up the path towards Etnach. At the top, go through the gate and there is a track immediately on the left that goes all the way to the top of Black Craig (and continues down to Halfway Hut). It is all rideable, just about, but is getting very overgrown and it would probably be quicker to run. Not that running would be much fun given the deep heather. Returned back to the gate, went back through it and immediately on the other side there is a track that goes down to Ballaterach and near to the rocking stone. It is indistinct to start with, then very boggy, but just before it starts to go properly downhill there is a big cairn on the left. This is as close to the stone as you can get on a bike, it’s only about 200m away. From here down the track is very good riding, although the farmyard at the bottom spoils the experience a bit. Only 13km in total with 400m climb but it took me 90 minutes.
