I drove thru Portlethen, past the police station and church pulling in at the Mains Of Portlethen farm. (note where I parked) From here walk to the track on the severe corner and follow the path to its end, turn south and the path leads straight to the fort. (no fences!)
A narrow passage leads to the fort which has a natural harbour to the north and a dangerous inlet to the south. The cliffs are of course very dangerous so watch your feet. Massive earthworks protect the fort from the land side. Like Gladman found at Garn Gawr so I found here, a gun emplacement was here during the 2nd World War, the military had been in action. The earthworks have been split in two to form a walkway. Two concrete slabs allow the walker to cross.
So all in all a very nice place. On the way back to the car wasn't so nice. Waiting at the gate to the track a farmer stood and waited for my return. His language used I won't replicate here but to say he was annoyed was an understatement. After giving my ears a severe pounding for 15 minutes, he was astounded to see me walk past the car in question. I kept walking and he stood amazed having built up a good rage for nothing. The guilty person was just walking past my car with her dog. With a wee word of warning I left the scene. To be fair the farmer was right as her car blocked two gates. Good fun!
