Kathmandu Valley is the cultural, commercial and administrative center of Nepal. The valley comprises three medieval Malla principalities-Kathmandu, Patan and Bhaktapur. In the medieval time, these three principalities maintained very fierce rivalry and fought several wars but also contended one another in building temples, palaces and development of arts and architectures; many of them still exist with all charm and glories and have been listed by UNESCO as World Heritage Sites. You will visit the temples, palaces, stupas and monasteries of the three cities and also take an excursion to Nagarkot- a famous destination for the views of Himalayan Panorama. Nagarkot lies 20 miles (32km) north east of Kathmandu at an elevation of 2000m ( 6560 ft). Nagarkot is famous for Himalayas and country panorama.
