The lay-by mention by Chance is the ONLY place to park when accessing this site.
Be careful when walking along the narrow road as it is a busy road and on several occasions I had to jump up onto the verge in order to keep safe!
A metal field gate gives access but despite wandering up and down I could see no obvious trace of any field works etc?
I did however get stung by thistles which gave a change form being stung by the more usual nettles!
Nothing to recommend a visit I’m afraid.
