Will the main route up Coire na Tulaich be likely covered in rock hard ice / snow this weekend making for a dicey top out for walkers? Is this also the recommended descent in winter?
Only done Buachaille Etive Mor in non-winter conditions.
Snow is soft and wet today according to SAIS report, but a gradual refreeze is expected over the weekend. It's also possible to descend the ridge on the W side of the Coire (assuming you are not intending to do the full traverse)
