The Pushkar Lake is a one of the holiest place for Hindus. There are 52 ghats(steps) around the lake, where pilgrims pray and take bath to wash away sings of whole life. The white buildings/temple around the lake looks very beautiful on a sunny day.
There are many mythological stories of the lake. Do hear some of those from locals and sadhus around.
Note: Photography is prohibited of bathing area.
