Rahba Kedima, Marrakech's spice square in the medina, is the canonical place to buy ras el hanout, saffron, dried rose buds, orange-blossom water blends.
Tip: Negotiate hard; first asking is twice the going price. The Berber pharmacy stalls sell argan oil and natural cosmetics.
Marrakech's Marche Central de Gueliz, off Avenue Mohammed V, is the city's modern produce-and-fish market: cleaner, organized, the fish counters at the back.
Tip: Visit early mornings for the freshest fish. Many stalls close mid-day for prayer and afternoon heat.
