I went trekking in December a few years ago. It is pretty desolate but amazing country side. We trekked from Aslil IIRC on a 3 day trek and saw 2 British girls as the only “outsiders”. After an hour we left the roads and up until the last 2 hours on the last day we walked on paths only accesable by foot or donkey. Might see if I can get some photos up later. It was very cold at night, but there were beds on the roof of the bunk houses we slept in for the summer. I wanted to bike but there was nothing there when we were there as it was off season. Much prefered it to Marrakech (sp?)
I would love to go back and do some biking
