Try to catch metropolitan buses to travel around in cities. You will save money (5-10 rupees for a ticket) and pollute less than if you were travelling by rickshaw (up to 100 rupees for the same journey and clouds of black smoke behind you). Furthermore, it is a good experience to interact with locals.
A rickshaw driver asked us 200 rupees for a ride to Amber Fort, which is about 10 km north of Jaipur. We found out there was a metropolitan bus going there for just 7 Rupees. It is a good idea to always enquire the local people (not the rickshaw drivers since they will want to get your money).
