About Nizwa

Nizwa was once the capital of the Omani interior, and its fort, with a huge circular tower, still rises over the palm oasis. The souq sells silver, daggers and halwa, and the Friday goat market draws crowds from the surrounding villages. The falaj irrigation channels and the ruined fort at Bahla, both listed by UNESCO, are nearby, as are Jabrin castle and the terraces of Jebel Akhdar. October to March is the best season; summer heat in the interior is severe.
