Thre was someone on DP asking for advice about the CRTT a couple of weeks ago...
It's not that person - I've exchanged messages with them and that trip is not planned until November. I have sent them the survey and - coincidentally - the trip report that SimonRL has provided a link to.
I'm the person that said it was a piece of cake on Darkplaces and i stand by that comment...it is an easy trip...its neither technically challanging nor particularly arduous
Not a piece of cake to you, JB, but the massively increased public awareness of the trip has made is accessible to people who treat it without the respect that it deserves - and indeed accessible to some do not have the necessary experience for it.
There's a video on YouTube made by a caving club that goes on about goblins (or something similar) that gives the trip a glossy, fun, themepark feel and in my opinion those people have been damned irresponsible in posting it. Indeed, the trip is not
technically difficult, but it can bite - as this has proved.
For my part, I've always worried that the trip is going to harm someone:
Croesor is an unstable
old mine, not a (relatively) more stable
natural cavern. Indeed, the first part of the trip has been created by a massive roof-fall which happened in 1932 (?) and the way out at the
Rhosydd end was effectively blocked by a series of falls in the 1990s.
More recently, the hole in the floor in
Croesor collapsed about five years ago; the ladder bridge was taken out by a roof-fall;
MountainPenguin (?) has witnessed a lump of roof falling in the
Chamber of Horrors; while a roof-fall in the first chamber came very close to killing two people a while back.
Thus, whilst the trip itself may be "neither technically challenging nor particularly arduous", that's not to say there isn't a risk due to the environment it's in.
Add to that the fact that you need to be prepared for two
80' abseils after perhaps 6 hours underground and some reason for coming back that was unexpected and you have a recipe for cave rescue getting called out.
As indeed has happened.
