India is set apart from the rest of Asia by the Himalayas, touching three large water bodies and is immediately recognizable on any world map. This thick, roughly triangular peninsula defines the Bay of Bengal to the east, the Arabian Sea to the west, and the Indian Ocean to the south. India holds virtually every kind of landscape imaginable. An abundance of mountain ranges, desert, mega cities and national parks extends a good 2000 miles (3200 km), from north to south. Himalayas, the world's highest mountain range in Nepal as its Neighboring country dominate India's northern border. Following the sweeping mountains to the northeast, its borders narrow to a small channel that passes between Nepal, Tibet, Bangladesh, and Bhutan, then spreads out again to meet Burma in the "eastern triangle." Apart from the Arabian Sea, its western border is defined exclusively by Pakistan.
