SH740455
Directions
The driest and easiest route is to park at the Welsh Slate Car park at the head of Cwm Teigl and walk along the Rhiwbach tramway to the Quarry. Then head over the tips, past the Craig Howell workings, skirting the woods until you reach the New Vein Quarry. Walk over the lake on the causeway (an old tip run). Climb up the steep slope behind the blocked adit, walk through the trees for 50 yards...and you will come to a crater, probably made about 70 years ago. Climb down towards the south western lip and the adit is exposed at the bottom of a collapsed chamber. (Level1 chamber 1)

Description
An interesting way (the only way!) in to the New Vein workings. This is a collapse which occured after this part of the mine was abandoned. It seems stable, there were no new rockfalls since our first visit 4 months previously. You go into the exposed chamber and see the adit from the pit going inbye, right to left. Go left of the pillar and down to where you will pick up the adit again. This leads into a very ochreous chamber with a shaft coming in from above. It looked as if there was possibly a further tunnel leading on, but the gloop gets deeper and deeper.
