No pics, but I went up Cadair with a mate in late Jan and it was pretty good. We followed the route from MBR, and there was a fair bit of fireroad style slog but it was still enjoyable.
Good sense of achievement at the top! And we had a lovely clear day, so some great views.
We started from Abergynolwyn; most of it was rideable until we got near the top; then it either got too steep/rocky or levelled off, but was a mass of large rocks that I couldn't ride through. Coming back down was a real blast though….pretty much rode all of it apart from a couple of dabs.
I'd not go when it's likely to be busy as there's a series of rock steps that you can hurtle down, but I imagine during peak periods you wouldn't get a clear run at them.
We got mainly shouts of encouragements along with comments like 'you're not seriously riding back down there are you?', 'you must be nuts' etc…..we didn't get any negative comments from walkers, although got a few icy glares, which obviously resulted in the obligatory extra cheerful 'Hello' in return.
