A popular day tour from Yazd is to visit Kharanaq, Meybod, Ardakan and Chak Chak. I asked for it at Silk Road Hotel and they arranged for the driver and guide Hassan to come the next morning. The tour was IR 350 000 (July 2006), so it is good if you can find someone else at the hotel to share the price with.
We first went to the village Kharanaq and after to Meybod. I asked for Ardakan, but Hassan wondered what I wanted to see there, as there was nothing to see. We went there (as it is very close to Meybod), but the bazaar was closed and people were going to Friday prayer at the mosque. The last stop was Chak Chak. We didn’t stay to have lunch, but only ate snacks. But I’m sure if you want to stay for lunch somewhere it is okay. Bring a lot of water as it is very hot. It was 46 degrees C the day I went on this tour.
