I can't recommend this trip enough.
We were messaged the day before, with a pickup time. The driver arrived on time and he was great. He spoke multiple dialects and couldn't have been nicer. The 3 hour drive up into the Atlas Mountains was comfortable and relaxing, and the half way coffee break was a nice touch.
The falls are a thing of beauty, the images online do not do this place any justice. It's truly breathtaking and one of the most stunning places I've visited.
The tour guide was amazing, he kept us all together and really made the most of our hike. We were shown around the local homes and met the women who make oils and creams from the local produce. They gave us tea and biscuits, truly humbling!
The boat ride under the waterfall was a nice touch! And the food in the restaurant overlooking the falls was amazing. So tasty!
The monkeys are cheeky, but friendly.
Be wary of the locals that "give" you food for the monkeys. Most of them are fine, but we had a guy that followed us around demanding money for a small piece of crushed up biscuit that he practically threw into my wife's hand. Our tour guide was on to him instantly and kept him away from us.
All in all, an absolute dream of an excursion, and I highly recommend it.
Note: not good for wheelchair users or pushchairs.
