The not-to-be-missed Wadi Dahr Rock Palace is perched atop a column-shaped hill—an impressive setting. It's said to be Yemen's most photographed building. After seeing it, stroll through the nearby villages, visit the qat orchards, stop at the teahouse, observe the excellent view from the Wadi walls and seek out the rock paintings. Wadi Dahr is usually seen as a three- or four-hour trip from Sana'a, but we think you may want to stay longer. 10 mi/15 km by road northwest of Sana'a.
