Most of the Agadir's petit taxi are quite legal and use the taximeter you can ask the driver to do it without any problems. If you go around the center, they will ask you normally from 10 to 20 Dh.There are also some buses but, as usual, they are very crowded, slow, and pass with low frequency. The touristic city is small enough to go walking instead of going by bus.
Since 2011 there is a new bus service which is quite reliable. Maps can be obtained from the Tourist Office which is along the Boulevard Mohammad V near the Miramar Hotel. Fares are usually less than 10dh.
