Our underground program offers a wide selection to cater for a wide range of capabilities ranging from easy walk ins to SRT. Our Health and Safety commitment is such that at no time will any delegate be exposed to unnecessary risk, or expected to do something not described in the trip "TECHNICALITIES".

However, it is necessary for all delegates participating in field trips to be covered by the usual public liability insurance. We will be arranging short membership with a participating organisation for those who do not have such cover.

Delegates booking onto underground trips will be expected to have personal equipment suitable for the type of trip they are booking on. Absolute minimum is a hard hat with chinstrap and attached electric lamp plus sturdy footwear.

Underground, the meet leader is in charge and anyone unsuitably equipped or demonstrating behaviour likely to be prejudicial to the safety of the group will be rejected.

Generally mines in the area are easy to explore and most can be done in waders or oversuit and fleecy, whatever. There are no winch trips, I'm afraid Ceredigion does not hold such niceties, and only 4 trips require SRT, although the upper ladder in Frongoch 18 fathom rise will require a lifeline as its a massive 18 feet, wow.

This is opportunity for the non technical to explore some very interesting mines and being a 5 day event, its well worth travelling a distance.

Underground Trips


This is probably the largest single mine in the area and exploration is a longish trip.

Entry from a manhole in the hillside by short easy fixed ladders, no lifeline required, into deep adit and thigh deep water. About 3/4 of a mile of adit to Engine Shaft with pump rods and other bits. 80 foot laddered rise to 18 fathom level .

Engine shaft with pump rods and remains of surface balance bob dragged down when the rods were released. Stope with clog prints, kibble and other stuff.

All day trips due to new additions. Start times will be from 10.30 hrs staggered for each party by about 30 mins.

TECHNICALITIES: Moderate but a longish trip with some stooping. No SRT but belay belt and jammer for lifeline on fixed ladders. Thigh deep water in places. Optional swims, plus a grotty crawl.

Most of the mine can be seen without getting wet.



Bwlch Glas Mine.

SRT down to Deep Adit with cages, artefacts etc.

TECHNICALITIES  Trip1 Fixed ladders 60ft, vertical freehanging 60 foot pitch.

Trip 2. Very wet walk in, winze with kibble etc..

Trip 3. Short self led, upper adit, fairly dry.

Access by kind permission of Mr Bernard Moore


Not available in 2013. Access through CAL

Long straight adit leading to stopes and side passages. Ore barrow stope has an ore barrow in really good condition. Waterfall Stope is a handline descent of large stope with 2 waterfalls and some interesting 'mooches'. Belay belt and cowstail required. Further passages on main adit has clog prints and candle stubs.  Possible round trip (optional) requiring SRT and waterproofs. Delegates can do as much or as little as they wish.

Trips running all day from 10.30 am with 'casual' leadership.

Full details: Henfwlch

Alltycrib (Talybont).

Not available 2013. Access through CAL.

Subject to permission the Forestry barrier at Talybont will be open for the duration of the event and so provide ample on site off road parking in a particularly pleasant shaded area surrounded by relics of past mining activity. This will enable easy access for anyone with some spare time to kill by an interesting self lead surface walk or easy underground walk in. Downloadable guides will be available.

Trip 1: Deep Adit

TECHNICALITIES Easy SRT down a 40 foot slope of about 55 degrees, a free standing rebelay, followed by a 20 foot slope. 70 foot descent by concrete steps and fixed ladders. No life line needed. Thigh deep wading or optional deeper water heading outbye.

Remains of horse whim and pumping bob plus flat rod supports. Remains of early wooden kibble and later iron one.

Trip 2: Western Engine Shaft stopes.

TECHNICALITIES Moderate SRT, 140 foot pitch in 2 sections, standing in the middle - rebelay. Further 30 foot pitch. No freehanging, reasonable slope. Short crawl through recent steel and concrete reinforced section.

From Wikinsons Level, easy walk in, shallow water, the SRT descent takes one down to the 10 fathom level, then the 20. Last pitch takes one onto a rubble floor above the 30. Spectacular vies up shaft and large stope.

Trip 3 Wilkinsons Level

Easy walk in, non technical, shallow water., short crawl as above. Can be self lead.

The level starts as a cross cut and appears to be a modified earlier coffin level. A left branch follows Wilkinsons Lode to Western Engine shaft and the SRT winze. The shaft is completely run for all its depth. A right branch cuts Felix's Shaft which was the site of an oil engine and winch used in the last 1910 working, foundations to be seen. The level eventually reaches Steel Ore Lode stopes. An easy explore.

Trip 4 Myddletons Level

Easy walk in, non technical, shallow water. Can be self lead.

Interesting example of Elizabethan coffin level. I have only identified one shot hole. Was the site of an underground steam engine in the 1870s, bits of the flue and boiler plate can still be seen at the run in at the end where it originally cut Western Engine Shaft.


Level Fawr Trips

Easy access to the back workings by The Steel Road rather than the small plastic tube.

Trip 1 TECHNICALITIES Hands and knees short entry through roomy tube, water up to thigh deep

General mooch in the level with lots to see plus  an all day underground ‘event’ in Lefel Fawr with a series of underground talks with groups moving between leaders.

#1 Underground Works, the challenges and difficulties by Roy Fellows.

#2 Geology and Mine Exploration, Prof David James.

#3 A self guided tour on a ‘one –way’ system.


Short ladder of a few feet to look at skipway.

















Trip 2 As above, plus

TECHNICALITIES moderate SRT down skipway to lower workings, about 80 feet.

Aldersons and Herberts Levels

TECHNICALITIES: None, except possibly wet feet

Easy  walk ins, fairly dry. Will possibly be combined with a surface walk.

Taylors Level

TECHNICALITIES: Water up to waist deep

[More maybe]



Mines of the Rheidol Valley.

 Leader Ioan Lord

TECHNICALITIES: None, except possibly wet feet.

Mixed; Surface and optional short easy walk in undergrounds. Highly recommended. Ioan lives in the valley and has spent a lot of time studying them. Basically, a repeat of a WMS field trip which turned out to be one of the best.

Get his book!

Ystrad Einion

Site of the famous underground water wheel.

TECHNICALITIES Easy walk in, ankle deep water, fixed temporary aluminium ladder with lifeline to upper level, life lined traverse over flooded understope.

Lefel Fawr at Pontrhydygroes

TECHNICALITIES Shallow water, some crawling, roped climb up to upper level.

[More details to follow]


Mine of the black cave pearls

TECHNICALITIES: Handline down open cut, wriggle through hole into deep water.

This is preferably a wetsuit trip and is subject to access continuing to be physically possible.

New Level

Extensive trial.

TECHNICALITIES: Open entrance but very wet, chin deep water in entrance.

This is preferably a wetsuit trip



Cwm Rheidol No 6 (Aldersons Level Fawr)

TECHNICALITIES: Stiff climb over uneven ground to reach the mine. Mine itself is shallow water and ochre. Quite nanky.

An interesting complex of adit workings draining the workings of Ystem Tien

Possibility of several different trips vertical and non vertical walk through's



Combined surface and easy underground. In dry weather the adit is bone dry! Although really a trial its and interesting easy walk in. Surface remains include flooded shaft with remains of bob.
