Bolivia
Bolivia is a landlocked nation, which means every border of Bolivia is a border with another country, and so it does not have a sea. It used to own some of the Pacific coast, but it lost it in 1879 in the War of the Pacific. The west of Bolivia is on the Andes mountain range. The highest mountain in Bolivia is called Nevado de Sajama and it is near the city of Oruro. Although this part of the country is very high with lots of mountains, there are also parts of Bolivia which are very flat, and parts of the country which are very near sea level. There is also a bit of Bolivia covered by the Amazon rainforest, and a big lake which is the highest lake in the world. This lake is called Lake Titicaca.
