Pakistan contains some of Asia's most awe-inspiring landscapes, amazing trekking and a multitude of cultures with a long tradition of hospitality. The country offers a vast archaeological heritage, with sites such as Moenjodaro & Harappa and Taxila & Takht-i-Baht, seats of the Indus Valley and Gandhara civilizations respectively. In addition to these sites, Pakistan boasts a wealth of architecturally significant buildings, many dating from the Moghul Empire in places like Lahore, Multan & Peshawar. The legendary Khyber Pass is the most important pass connecting Pakistan and Afghanistan. Invaders have used the pass to reach India since the times of Alexander the Great. The Hunza Valley, also known as "Shangri La" from James Hilton's novel "Lost Horizons", is an area of stunning natural beauty. Down in the valley the Hunza River thunders along; rising above that are endless terraces of orchards irrigated by the water from the glaciers nestled in the huge Karakoram Mountains towering above. Pakistan is a land of high adventure and nature. Extraordinary trekking, mountaineering, white water rafting, mountain & desert jeep safaris, are just some of the few activities which make the country so enticing.
