Have you checked the forecast for Snowdonia on the Met Office website? It's not looking too brilliant for Sunday. You might also want to take a look at some of the Snowdonia web cams before you head off.
Hey. It's not too bad. I'd set off early before the sun has had chance to loosen the snow too much. I had very little touble with ice (apart from in the carpark!).
I imagine it might be a bit trixier up on Crib Goch. Ice axe was really rather helpful.
40 mins!? I would be out there every week! Bournemouth is far too flat!
Luckily I can take work off at no notice so some better planning and hopefully some more snow this year and I will head up. Want to get the crampons and ice axe out
