From afar, the Kejetia Market looks like an alien mothership landed in the centre of Kumasi. Closer up, the rusting tin roofs of this huge market (often cited as the largest in West Africa; there are 11,000 stalls and at least four times as many people working there) look like a circular shantytown. Inside, the throbbing Kejetia is quite disorienting but utterly captivating.
There are foodstuffs, second-hand shoes, clothes, plastic knick-knacks, glass beads, kente strips, Ashanti sandals, batik, bracelets and more.
Wandering around the market by yourself is absolutely fine: few tourists come here and shopkeepers will be pleasantly surprised to see you. Alternatively, go with a guide, who not only knows his or her way around but can also explain the more obscure trades and goods, and help you bargain and meet stallholders. Allow about C10 for a two-hour tour; contact the Ghana Tourist Authority or your hotel for recommendations.
