Drive to Godavari (18 km from Kathmandu) botanical garden and gradually hike up to the ridgeline. At several points you come across a gravel road that leads to the summit of Phulchowki(2829 m). The summit is the highest point in Kathmandu valley. Throughout the up hill trail and road there are thick bushes of rhododendron trees and orchids flowers. In the spring it is pleasant to see colorful flowers all over the forest. This area is equally great place for bird watchers. In December, sometime there are snowfalls on the summit. The ridge top provides unobstructed wide-angle view of the Himalayas stretching all the way from Everest to Annapurna. At the summit there is a Buddhist stupa and colorful flags offered by devotees. You can either descend to Godavari (about 3 hours walk) or have a 4 wheel drive pick you up at the summit.
