Tang-e Chogan information
Lonely Planet review
About 4km along the gorge is the Tang-e Chogan and its awesome 7m-high Statue of Shapur I , one of the most impressive archaeological sites in Iran. Getting to the cave is easiest on a taxi tour, but you could walk the 5km or so from Shapur. Take the road along the river for about 4km to a village on your left, where one of the villagers will probably offer to lead you up the steep ascent to the cave (start very early in summer). A tip is appreciated.
