Buses do not ply direct to Aït Benhaddou but can drop you off at the turn off about 7 km away from where you will have to find a lift.
It will be better to arrange a private hire of a taxi for the trip.
At daytime, grand taxis are always waiting at the crossing. A seat costs 9 Dirham to which they might add for luggage. The cost for the whole taxi will be 60 Dirham.
Car: Aït Benhaddou is 9 km off the main Tizi n Tichka road, which links Ouarzazate to Marrakech. Coming from Ouarzazate, turn to the right after about18 km from the town. It's quite a scenic drive to Aït Benhaddou. On the way into town there is a slight turn to the right, which is a popular spot for great views over the town and the Kasbah.
From Marrakesh it will be a full day trip and the best advice is to organize a private tour if you do not have much time.
Once inside the Ksar you can only walk or climb. There are two main entrances into the Ksar. One can be reached by new bridge. To reach the second, it is necessary to cross the river using the stepping stones (in dry season the river is completely dry).
The town itself is the main attraction, with mud buildings climbing up the side of the hill.
The Granary at the top of the hill is impressive and well worth the effort to get up there, though be careful of any little 'entrepreneurs' eager to help you climb to the top level inside the granary. They wait till your back is turned before quickly dissembling their makeshift bridge which you used to climb up and it's not until you throw down some baksheesh that they'll let you climb down again.
The Mausoleum of Ben-Haddou is at the base of the hill on the opposite side to the town.
There are several shops within the town that sell souvenirs from all over the Sahara, particularly prevalent are Models of the Ksar and wooden artifacts from the Dogon people in Mali.
There is a very friendly carpet shop in the newer part of town near the post office.

Grand Taxi back to the crossing 9D per seat, then 14D to Ouarzazate. You might also be able to catch a bus to Marrakesh (they stop if they have seats available). There's a local bus that goes past the crossing at about 10.30am to Agadir and another to Marrakech at about 10.45am (4hrs).Local buses only have destinations in Arabic so unfortunately you'll just have to flag them down and ask the driver where he's headed.
