After a short time of contemplation and relaxation I decided I had to explore the Engine Houses I could see down on the side of the cliff
It was fantastic
That said to get behind them for these shots you quite literally stood on a 12 inch wide path of slippery mud with a 100ft drop.
You can climb all around these safely, just not in motorbike boots, if you go (I highly recommend you do) take a pair of walking boots or similar to change into and you can get the most out of this fantastic location.
Having lunch on the wall on the engine house is highly recommended.
