Bolivia is a country on the South American continent. Bolivia is located to the southwest of Brazil and shares borders not only with Brazil, but also with Argentina, Paraguay, Chile and Peru. The longest border is shared with Brazil though. Bolivia is less than three times the size of the state of Montana/USA. A flight to La Paz takes about 17 hours from London, and about 12.5 hours from New York. Bolivia is a landlocked country. This means the country does not share any border with an ocean. Bolivia, however, claims part of Lake Titicaca, which is the world's highest navigable lake at 3805 m/ 12483 ft. There are regular border disputes over access to Lake Titicaca with Peru, which also claims territory.
