From start of track to reservoir at NS274900. Solo. Warning signs and sight of three bulls caused me to deviate into the field to the east of the track. From near reservoir easy climb to the summit of Beinn Chaorach. Weather really nice so excellent long distance views to Arran and Ailsa Craig. Went over Beinn Tharsuinn and on a track towards Auchengaich Hill before descending down to the reservoir track. Met another walker who assured me the bulls were docile so used the track all the way to the car. The bulls did not budge at all!
