Peak Climbing Nepal is considered one of the best adventure destinations in the world. Nepal's geography packs an extremely varied landscape into a small area. The immense contrasts in altitude and climates found here support a spectacular mix of lifestyles, vegetation and wildlife. Nepal is probably the only country in the world where you can climb the highest mountains in the world. The core of the mountain complex known as Himalayas ‘abode of snow’ is the youngest and highest mountain system of the world.
