Shivapuri Nagarjun National Park

Listen first. Under the trees, the city noise drops away almost at once. Dry oak leaves crackle underfoot, a stream runs somewhere below the trail, and the air carries the cool, green smell of moss and damp earth. Only a short drive from the prayer flags and butter lamps of Boudhanath, you are standing at the edge of the forested hills that rise along the northern rim of the Kathmandu Valley.

This is Shivapuri Nagarjun National Park. It is one of the youngest national parks in Nepal, and also one of the closest to a capital city anywhere in the Himalaya. The protected land wraps around the valley's northern hills like a dark green collar. On a clear day you can see it from the rooftops around the great stupa. Most visitors never think to look up.

The park has two parts, and the double name reflects that. Shivapuri is the larger, higher block of forest to the north and northeast. Nagarjun is a separate wooded hill to the northwest of the city. For years they were managed as different reserves. Early in the twenty-first century they were joined under one name. Today the park covers roughly one hundred and sixty square kilometres of forest, streams and ridgeline.

Why protect these hills at all? The answer is water. Kathmandu is a thirsty city, and much of its water starts right here. Rain and mist collect in the forest soil and feed the springs below. Long before this land became a national park, it was guarded as a watershed. The pipes and reservoirs near Sundarijal, on the eastern side, have supplied the valley for generations.

Here is the first surprise for many visitors. The Bagmati River begins inside this park. The Bagmati is the sacred river that flows past Pashupatinath, the great Hindu temple where cremations take place on the riverbank. Its source lies high on Shivapuri, at a place called Baghdwar. The name means the tiger's door. Water emerges there from a carved stone spout shaped like an animal's mouth.

So the river you may have seen, slow and grey beside the funeral ghats in the city, starts here as a clear and cold mountain trickle. Pilgrims climb to Baghdwar to honour that beginning. Standing at the spout, you can feel how closely the faith of the valley is tied to these quiet hills. The sacred and the practical meet in the same stream of water.

The summit of Shivapuri rises to roughly 2,700 metres above sea level. That is far higher than the valley floor, and you feel the change as you climb. The forest shifts from pine and chestnut lower down to oak and rhododendron near the top. In spring, the rhododendrons flower deep red. Rhododendron is the national flower of Nepal, and here it grows as full trees, not garden shrubs.

The forest is also home to more wildlife than most people expect so close to a city. Rhesus monkeys move along the trails, often bold and curious. Barking deer call through the undergrowth. Leopards and Himalayan black bears live in the deeper forest, although visitors rarely see them. Birdwatchers come for the many species recorded here, and the morning chorus can be remarkably loud.

The hills hold a long spiritual history too. On the Shivapuri side, a Tibetan Buddhist nunnery called Nagi Gompa sits on a high ridge. Nuns live and study there, and the sound of chanting can carry across the slope. Remember that this is a working religious community. Walk quietly, ask before taking photographs, and keep your voice low near the buildings.

The forest also sheltered a famous hermit of the twentieth century. He was known as Shivapuri Baba, an ascetic who spent many years in meditation in these woods. A shrine linked to him still draws visitors. Many stories surround him, including claims about an extraordinary lifespan. Locals tell these tales with affection, but they are best heard as legend rather than documented fact.

Nagarjun, the western hill, carries its own legends. Its name is linked by tradition to Nagarjuna, a great Buddhist philosopher of ancient India. According to popular belief, he once meditated in a cave on this hill. Historians cannot confirm that story. Still, the cave remains a place of devotion, and a small stupa crowns the summit, called Jamacho, wrapped in fluttering prayer flags.

For walkers, the park offers very different experiences. A short climb from the Budhanilkantha side brings you into shade and silence within the first hour. A long day hike can take you all the way to the Shivapuri summit and back. Many trekkers also start a multi-day route north from Sundarijal, heading towards the mountains of Helambu. The trails are steep in places, and the forest floor is often slippery after rain.

Notice how the light changes as you walk. On the open ridges, the sun is strong and bright. Under the oaks, it turns soft and green, broken into small patches on the ground. On clear mornings, especially after the monsoon, the high Himalaya can appear far to the north, a white line above the dark hills. Some days the clouds hide them completely, and the forest becomes a quiet world of mist.

Before you leave, pause for a moment and look back towards the valley. Somewhere down there, the white dome of Boudhanath sits among the rooftops, and the city carries on with its traffic and its prayers. Up here, the same water that will feed the Bagmati is moving slowly through the soil beneath your feet. Listen once more to the leaves, the birds, and the stream... and then take that quiet with you down the hill.
