I was wondering if anyone knew the names of two adits either side of the footpath that leads off Griff Grange Valley towards Griff Grange Farm, from the second lay-by on the left up from Rider Point? The right hand adit has the remains of a coe and goes in a fair distance with metal rails in place and plenty of bat poo, whilst the adit on the right doesn't go too far due to collapses and passes a fantastic Shelob's lair.
