I am often asked about hiking around Granada.
Here is some useful info if you like hiking. 

Granada is a wonderful province for walking especially in the winter when most days are sunny and cool enough. After May it gets too hot unless you walk high up in the mountains. Here are the ones I know about. There are commercial walking tours but the ones ones I mention below are all free.
