Considering riding at Brechfa tomorrow but wondering if the trails are impassable?
Don't know about the trails but the area in general was hit pretty hard by Storm Darragh. Some roads were still impassable when I was working over there week before Christmas. Huge areas of trees down.
The Troserch Woods trails near Llanelli are all open bar one trail. They are short and sweet but good fun if you are nearby.

Hafod trails also open I'm told. Weather is awful here at the moment though!
Any update on this?
It always seems that Brechfa is closed whenever I fancy a trip, so not holding my breath…
No trails are anywhere near being open. It sounds like the local club might have permission to start doing some basic work but the shattered trees across whole hillsides mean it’s a huge job. 
Thanks. That looks apocalyptic.
I took a look at Brechfa today. There's some progress with opening the trails. The Derwent green is open. It's the trail with the warp speed roller coaster jumpy descent that flies back down to the carpark.
The blue variant is still unavailable 😔.
The Gorlech (red) is partially open but much of the fun is inaccessible because of the damage from the storm.
The Raven (black) can be ridden in a shorter format that includes the corkscrew, the jump section and the four tops (the big ol' tabletops). The singletrack return is fine but the log bridge is closed sadly.
I decided to do an XC route instead; the area has a very lot of many cracking RoWs indeed. Bergwm- Pentre Evan - Banc Farm is still a favourite of mine. The meadows at the top are sublime, say "hello" to Pen y Fan before using the slippy rocky track back to the valley.
Inquisitiveness got the better of me though and when I found an unmarked trail of course I was tempted - only to pop out at the top of the Derwent climb up from the Riverside hut. It would have been rude not to return on the Raven though. So I did. And then the final km of the mega fun Derwent.
Moral of the story: take a map as well as tracklogs, there's still leads of riding to be had. 😁
Haven’t been this year I’m afraid. There’s a public Facebook group called Brechfa MTB (CIC) which is the official trail group so they should know more.
I was there today. Red is 'open' but is full of diversions, leaving lots of fire roads and a couple of sections of single-track I believe but can't confirm as I was at Bergwm.
Green and blue are open with diversions in place because one of the major bridges has been badly damaged. It's the bridge at the bottom of the Black 'corkscrew' where the black and green blue rejoin on the outbound.
Easy diversion in place that utilises the green climb up from the little wooden bridge as a descent. It's well signposted.
Back on track the blue and black share the same climb up the rebuilt blue.
Once we'd finished the blue descent, almost back at the damaged bridge we hooked left up the fire road to the jumps and four tops on the black. Max the dog was a bit tired so we headed back. The black is open here almost all the way back to where the initial descent and qualifier pops down to the river. To miss out the bridge there's a short climb up a steep rocky track, a byway.
Brilliant info. Thanks
