Park in the car park at Nantmor (south of Beddgelert – it’s called the Aberglaslyn car park) and take the footpath up and over the railway, up through the woodland and into the gully of Cwm Bychan. You will see the main adit (huge spoil heap) on the left halfway up just after the winding pylons.

Mine Attributes
Manganese. However other minerals exist including copper, iron, sulphur and fools gold.

Description

Main Adit
This is located at the top of a large spoil heap just north of the winding pylons and is probably the largest mine in the Cwm Bychan area. The adit itself is flooded to around 3 feet and travels inwards for around 200 yards where it comes to a T junction. Adits run left and right here for several hundred yards in both directions and become dry. At the T junction there is a shaft to surface around 60-70 feet in height. Both adits exhibit decorations, nails, mineral intrusions and some evidenc of copper (sulphate) remains in the left adit, as does some evidence of fools gold.

Above the entrance (scramble over the top and beyond) is another much larger entrance which is essentially a mined stope which seemingly leads back down to the adit. This is a dangerous descent without equipment (should not be tried) and, in any event, can be reached from the adit below.

Adit #2
This adit is on the left walking up Cwn Bychan a couple hundred yards before you reach the main adit. There is a small area of razed buildings which give away it’s location.

This adit is flooded to around 8-10 inches and has not yet been explored but ought to be “reasonable” in length due to the amount of spoil outside

Adit #3
This adit is on the right walking up Cwn Bychan a couple hundred yards after you reach the main adit. There is a small area of spoil which gives away it’s location.

This adit is flooded to around 8-10 inches and has not yet been explored but may have limited prospects due to being on the other side of the gully to the main workings.

Adit #4
This adit is on the left walking up Cwn Bychan a couple hundred yards after you reach the adit #3 There is a small area of spoil which gives away it’s location.

This adit is flooded to around 8-10 inches and has not yet been explored but may have limited prospects due to the small amount of spoil outside

Note : There are known to be more adits in the immediate area which have not yet been located

Unexplored Passages
Adit #2 remains unexplored
Adit #3 remains unexplored
Adit #4 remains unexplored

Digs
None Known
