Tiznit is in northern coastal part of the Anti Atlas.
Tiznit does not offer much for typical short-term tourists except silverware. But it is a great town for a few hours wander or stocking up when on longer trips and to enjoy some civilization again.
Temperatures in Tiznit can be really high - way above 50°C! Go there either early morning or after 3PM to avoid these brutal temperatures. It is much more pleasant to visit in the early spring when temperatures are around 25°C.
When in town, take a local bus to Aglou which is just a few kilometers away but at least 10°C cooler and with a nice breeze from the sea.
Tiznit is located on the N1 and is easily accessible by car. Parking is easiest outside the town walls, particularly in the Boulevard Hassan II area to the south west.
CTM and Supratours stop here on all trips south into Western Sahara. Note that CTM buses have a 30- to 45-minute stop at a gas station/restaurant just a few kilometers before Tiznit and thus the trip takes longer than the distance suggests. You might be lucky enough to catch a shared taxi that passes the gas station, but chances are very, very slim.
The walled town area is quite compact and easily walkable though can be disorientating off the main routes
Metered taxis are available.
Any type of household item - this is the place where Moroccans who live within 70-km radius do their shopping.
Silverware is sold by the gram and some nice designs can be found.
