Going to be doing the Croesor Rhosydd through trip on Sunday just wondering if any one had done this recently and had any up to date info regarding rope conditions new collapses etc. Also a list of gear needed would be handy as non of us have done this trip before IP: 82.132.247.179

I last went through in the first week of August this year and all of the fixed aids were fine, I was pleasantly surprised to find that the knee scraping traverse is now a lovely smooth zip line.
still took our own inflatable dinghy and rope though just in case but they were not required on this occasion.
perhaps someone has been more recently and can give you a more up to date report.

If you've not done it before, print out and laminate and take the Croesor and Rhosydd surveys (on this site), and read (or ideally take) some of the trip reports.

You all need SRT gear - for both up and down, you all need to be able to pass a rope protector and put it on again in the right place. You all need to be able to swim, consider buoyancy aids. Take rope(s) for the 2 pitches in case the in-situ ones aren't good enough. Pull the in-situ ones up and examine them very carefully before you use them, and consider lifelining the first person down anyway.

You may need a reasonably big pulley for the big zip line following the two pitches (although there is usually one on there). You should take a good length of cord in case you need it to send the pulley back (again, there's usually on there). Put a sling or something over the wire rope in case you need to use it to brake when approaching the far side.

The traverses are mostly OK- providing nothing goes wrong! You need a pulley and cows tails. Work out how to get someone off the traverse line if they slip etc.

The canoe in the chamber of horrors is superb - but best to take an inflatable boat in case it isn't....

Small (15 foot) SRT pitch up into Rhosydd.

Route finding in Rhosydd is interesting. Go along and up a grovelly scramble into Rhosydd proper. You can get to the surface out of the Twyl (big open quarry) but it's a serious climb. When you can see the opening of it head across and down and eventually you should get onto the incline down to the end of No 9 adit - it's only half a mile then to the exit.

It's a cracking trip - just be prepared to sort out anything that doesn't go to plan!

Come to think of it, there was NO pulley on the zipline when we went or if there was then I didnt see it, we used a petzl tandem and took a roll of para cord to retrieve it. definitely take a tandem pulley as well as all the kit mentioned in the post above.

Did this trip again today after a 9 year absence. I found it somewhat more straightforward now than it was back then; the additional rigging and more fixed gear has made the trip quite a bit easier/ less demanding in places. All fixed gear was found to be in good order; no issues other than the length of static rope which has (temporarily?) replaced the first zip wire. Attached to just a single bolt at the far side (there are other bolts!), this tyrolean traverse deposits you nicely in the water from the mid point onwards. A cold water enema is virtually guaranteed. Wink

The Rhosydd section beyond the second wall seems to be more complex than it used to be, possibly due to further roof falls. We exited directly via the West Twll - as it leads to a far more straightforward return to Chwarel Croesor if time is short. There's an easy zig-zaggy scramble up slightly dubious terrain on the LHS of the Twll looking out. The former 'trade route' up a straightforward little solo pitch on the slabby headwall hasn't been frequented for years and so is now totally buried under a thick carpet of moss and grass.

Hey Guys - some friends and I are hoping to do the Through Trip in October, but although we've had plenty of time in similar mines (Wrysgan, Cwmorthin traverses and tyroleans solo, Croesor as far as the first abseil, etc) and climbing experience, we've not got SRT skills or equipment (beyond trialling some SRT ascents up trees etc with prusiks). Blink

Sooooo... we were wondering if there are reputable guides available who are willing to take us through this route and provide SRT gear? Understand that we'd probably need to demonstrate a minimum level of competence! Big Grin

This sounds like a recipe for disaster...

Hence my comment regarding competence! Smile

I guess any LCMLA guide won't touch the idea with a barge pole if it is going to be unsafe. Only having access to things like the UK Caving wiki walkthrough, I thought that whether this was advisable, and whether there were guides out there who might be willing to help might be found here. If it's a stupid idea, then we can try alternatives (tag along as individuals on a club trip, etc).

Thanks for any advice! Big Grin

Unless CRTT is going to be your last ever mine trip it would be a good idea to get some training done and get kitted up. There are lots of other great SRT through trips and SRT only explores in the area, as easy or hard as you like.

But maybe it's just something you want to tick off the bucket list? In which case I think it will be difficult finding a suitably capable and willing guide.

If you do ever find yourself down there, consider buoyancy aids Thumb Up

As a 'professional guide' I can confirm that no qualified leader would ever be able to take you or anyone through that trip. It is out of remit for the awards, not an inspected mine venue (which is required by law) and a completely impossible place to guarantee safety of clients.
You are best off learning the skills and networking a bit to find a few locals who know it well and can take you through for fun. I'm sure there are plenty of people on here who would help with that. Keep an eye on the CCC website for the next subsidised SRT training course or hire a CIC direct for some bespoke coaching.

Dosserboy - I'm really sorry but they're right. You can't learn SRT in there, and you can't do the trip safely without a reasonable level of competence. It would be perfectly possible to take a beginner through - until something happened to them in the middle of a traverse or halfway down a pitch. The problem with SRT is that you need to be totally self reliant - this needs to be taught, practiced and perfected in easy accessible places, which the CRTT is not.

Very few people have multiple spare sets of SRT gear available to lend also.

So - what can you do? Here's a few suggestions :
Join a caving club, and learn SRT with them.
Do a SRT training course.
Buy some SRT kit and a rope, throw it over a tree branch and practice everything in the book.
Get an inflatable dinghy, go into Croesor and explore the flooded chambers to the right of the adit before the incline.
Get yourself a ladder and lifeline, and take your dinghy into Rhosydd to the connection. Have a paddle around the massive flooded chamber at the bottom of the 15 foot ladder.

If you've done some or all of all that, and you're still keen I've no doubt that there will be people on here able to assist you further. I'd certainly be happy to help you.
Good luck!

Anyone done this recently? I'm potentially looking to do this within the next couple of weeks after having done it last August. I noted all the recent updates concerning the state of the Zip lines/Ropes - any further updates to what they're like?? IP: 86.27.225.127 Edited: 29/06/2018 17:12:00 by AlexCaves
