The main attraction of this village being the monastery complex consisting of three monasteries. I believe these monasteries will remain the best kept secrets, since photography is not allowed inside.
The Walls of this simple looking mud structure are painted with various aspects of Tibetan Buddhism. The paintings said to be 1000 years old are something which are incredibly beautiful to describe.

Again, spending a day at Alchi, taking a early morning walk in the amidst the lush green fields, the small by lanes of the village, would be entirely refreshing.
