Pushkar is roughly 75 kms from my hometown (beawar) and as the vibe of famous Pushkar Mela was at its peak I decide to put in my weekend in city surrounded by beautiful aravalli mountains.
One can cover all the tourist spot in one day but lets take at least 2 days to indulge in essence of this city.
