We decided to go Lonavala, which is a 2 hr drive from the city.
We started early morning around 5:30am. It was still dark at that time and a little cold (Mumbai winters sort of cold). Had boost (boost is a Mumbai thing, bhaiya's on cycle sell boost just like chai/coffee) to warm up and then started the journey.
We left early to avoid the traffic and to see the sunrise in hills. Which proved out to be a success as we achieved both.
