The main attraction is the river and the river bank.Most attractions are the nearby gorges and villages along the Yangtze.
We were here in February, so book a good hotel with heating! Houses, museum, shops have no heating. People are very very friendly.
Surprise for us- modern clothes, a super supermarket, as good as Hongkong!!
Besides the dam, there is not much to see in Yichang. The only good thing about the place is, that is not very touristy, so it is very authentic and people leave you alone.
