We have been back from two trips- Imlil and Ouirgane valley- with Driss last May. It was the most relaxing, fun and well organised trips. We read about Driss from this precise website and thought to research about Driss. We found him! And found that he was a good guide.
We were travelling with our little toddler on our backpack and stayed in a Riad slightly further out from town. Driss was happy to pick us up even though it was slightly out of his way. He lives in Imlil so visiting his hometown was essential to understand the local context of where he grew up. Although so, we highly recommend Ouirgane valley if you're only planning to have one trip to the High Atlas Mountain. Driss organised a local guy Mohammed and his mule Katherina for the trek and every minute of the walk was just fantastic. We were even invited to Mohammed's home to have tea and lunch.
Driss took us around in the pace that suited us with our constant breaks to tend to our toddler on our back. He was also very good at interacting and playing with our little one which makes the trip for enjoyable for us.
Here's his website and we hope you have a lovely trip there someday. http://www.high-atlas-guide.com/
