During these weeks, pilgrims visit a series of local shrines from the mouth of the Tensift river south of Safi to the northern outskirts of the High Atlas Mountains, and including the city of Essaouira itself. They are led by two groups on a round trip stopping at every shrine on the way. One group must dress at every shrine a holy tent made of fan palm fibres and dyed with henna, the other group arrives in a procession with a muqaddim (religious leader) riding a white horse.
