In reply to Rhi Rhi:
We were there last year in late May. Stayed one night in Capileira, very pretty village, you can stock up here in some supermarkets, before heading up to refugio poqueira for Mulhacén. There are easy and harder ways to the peak, there was still plenty of snow around then. We then did some walking near Nerja. The difference in temperature between walking in the Sierra Nevada and the coastal range was huge. On Mulhacén we needed all our layers, whilst else where it was shorts and t shirts, and worry over carrying water (plenty of water sources in Sierra Nevada as we walked up a river valley Rio Nante.
Oh, and it was very quiet and fairly empty.
