NAMHO 2019: Trips
Last Updated: 28/01/2020



Thursday early bird specials

There are several trips scheduled for Thursday afternoon for early arrivals, see booking list.

#1 Henfwlch - Leader Roy Fellows. Flexible numbers.

#2 Pantmawr - Leader Ion Lord (He who wrote the book) Limited numbers.


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 5 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.

Frongoch Trip Details

Bwlch Glas Mine.

An interesting SRT trip (advanced) to the deep adit where there is a winze with cages in situ. Also optional very wet trip up deep adit to a winze with a kibble.

SRT down to Deep Adit with cages, artefacts etc.

TECHNICALITIES  Trip1 Fixed ladders 60ft, vertical freehanging 60 foot SRT 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


Bwlch Glas Details


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.


: Henfwlch Trip Details

Alltycrib (Talybont).

Not available 2013. Access through CAL.

 The Forestry barrier at Talybont will be open for the duration of the event ( permission obtained) 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 - Cancelled.

Trip 3 Wilkinsons Level

Easy walk in, non technical, shallow water., short crawl as above. 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. 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.

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

Crossroads Adit (SRT Through trip)

A nice, dry little trip.


Rosa Level/Pugh’s Mine (Advanced SRT)

This is a day long, multi-pitch SRT trip for a limited number of enthusiasts. Rosa Level is high on the hill, above the Cwmyswyth Mill and the trip involves multiple pitches to reach approximately back to road level in Pugh’s Mine (Western end of Cwmystwyth) and re-ascending via the same route. Those involved with this trip will need to be very experienced with SRT and be prepared to carry a lot of rope up to Rosa Level – need to be fit!

Rosa level : Pughs Mine

 Kings/Queens Adits (SRT)

This is a comparatively short SRT trip but into a part of the Cwmystwyth system not often visited and with interesting artefacts. Access is into the adit below Kings Adit, high up on the Eastern end of the Cwmystwyth system. There is a freehanging pitch of about 10m down to intermediate workings with artefacts and then an unconventional pitch descending to Queens adit. There is no surface access to Queens adit so exit is by re-ascending the two pitches.
