Before I finalised the countries in South America that I would be visiting, I took the effort to call up and speak to their respective consulates in India. The Bolivian consulate confirmed that visa on arrival is granted to Indian citizens at a cost of USD 60. The officials also provided me with a list of documents that need to be carried for the visa of arrival.
Internal flights in South America cost a fortune, especially if you book last minute tickets. I had blown up so much cash flying from Brazil to Bolivia that flying internally in Bolivia wasn't an option for me. There are no train routes in the country for passengers; rail is used to transport minerals. The only option I had was to hop from one place to another by bus, as most tourists do. So, I hopped on a bus...run by Bolivia Hop.
