I had a wonderful stay at Riad imNane Lodge. Everything was perfect from start to finish. The room was very comfortable, and the bathroom was clean and well-maintained.
A nice place to stay in, with a magical view from the rooms windows and rooftop on the high atlas mountains. The hosts are nice and helpful, I would definitely recommend.
The driver picks you up in Marrakech and in about 2 hrs gets you to imlil. The hike starts from there. For the first day the walking time is about 7 hrs with +800 mtrs elevation 17 km walking.
