If you're in Ziguinchor it's an easy hour's drive by taxi or minibus, depending on your budget. From anywhere else in Casamance it'll just take a little longer. If you're near any of the major tourist spots you're probably within 1-2 hours drive of the Women's Pottery Center of Edioungou. If you take a minibus, or sept-place, they'll drop you at the junction and you'll either have to hike in or get a local taxi.
