Rock climbing is another challenging sport for outdoor lovers. Most of the areas for rock climbing are situated toward the north of Kathmandu valley in the vicinity of the Nagarjun forest and the Shivapuri Watershed and wildlife Reserve. Because one is a national park and the other a protected area, trip to these places can be combined with hiking, bird watching and other activities. Nagarjun, 3 kilometers from Kathmandu city can be reached via Balaju near the new Bus Park. Shivapuri can be reached via Budhanilkantha, which is 9 kilometers away from Kathmandu.
