I will be in Yosemite during in late May, early June 2014 - I want to see the waterfalls at their best.
My ambition is to hike Clouds Rest. I understand that the hike if from Tioga Road. Assuming this is open, is the trail likely to be covered in snow? Would I need crampons? I am an experienced winter hiker in the British National Parks, but avoid hiking when crampons are needed.
