Medina lanes, Ben Youssef Madrasa, souks, a rooftop pause and Jemaa el-Fna towards evening.
Day 2
Palaces & Kasbah
Bahia Palace, Mellah, Kasbah lanes and time for a restful hammam break.
Day 3
Gardens & Design
Jardin Majorelle and the YSL Museum, then cafés and shops in Guéliz.
Day 4
Day Trip
Ourika for valley scenery, or ANIMA for an easier garden day nearby.
Day 5+
Go Deeper
Explore Sidi Ghanem, MACAAL or the Palmeraie; add a longer excursion only with extra time.
Honest thought: September rewards a slower pace. Keep exposed sights for the cooler morning, hold one day open for an Atlas outing, and leave afternoons for shade, gardens or a pool.
