We had a full day in Mamallapuram but chose to spend it in a folk museum 30km back towards Chennai - it was brilliant, with dancing, lots of old buildings dismantled and brought in, weavers, potters and hundreds of Indian tourists.
The next morning we did the bits of Mamallapuram we had missed including the famous "Shore Temple" and the "Five Rathas" - more carved rocks. And then the amazing shell museum which is exactly what it says on the tin a huge collection from all over the world.
We wanted to visit the famous Vedanthangal Bird Sanctuary so headed for Chengalpettu, where we seemed to be the only foreigners in town. Anyway, spent a great morning watching birds before returning for our now habitual veggie "meal" - basically a pile of rice with several small veg side dishes refilled as often as you can manage and all for less than £1.50.
All our travelling so far on local buses much to the amusement of the school children.
Now heading off to visit big temples.
