In reply to Joe123:
Tried to drive up Pen y Pass on Sat afternoon, gridlock! Cars doing 10 point turn to come back down. That's what I did as well. Snowplough tried to clear it but impossible cos of massive snowdrift on 1 lane. Walls on either side of the road, no point pushing the snow back to the middle of the road. Walls too high. Snowplough is useless. Then, I went around A5 way. Back down Pen y Pass in the evening, ok going up from Pen y Gwryd but sketchy coming down from Youth Hostel.
Today, I tried to go up Pen y Pass. A digger told me to turn back. A VW Golf drove down past me and said the other side (Pen y Pass to Pen y Gwryd) was blocked by spindrift now. It's perfectly dry road up to Cromlech boulders.
