Sagarmatha National Park: Walking into the Khumbu

Sagarmatha National Park covers the upper Dudh Koshi valley, the Khumbu, and the high ground around Everest, Lhotse and Cho Oyu. It was declared a national park in 1976 and a World Heritage property in 1979 — one of the first natural properties listed for both its landscape and its ecology.

The park is culturally protected, not just scenically

What makes Sagarmatha unusual among mountain parks is that people live in it. Sherpa villages, monasteries and high pasture lie inside the boundary, and the listing recognises the cultural landscape along with the ecology.

This means a visit is a walk through settlements, not a wilderness traverse. Tea houses, lodges and shops line the main trail, and very few people carry tents.

Permits and fees

Two things are required for the Everest trail: a Khumbu Pasang Lhamu Rural Municipality entry permit, and a Sagarmatha National Park permit. Both are collected at checkpoints on the way up; the park office at Monjo is where the park permit is stamped.

There is also a Trekkers Information Management System card for some routes. Rules and fees change — confirm at the Nepal Tourism Board in Kathmandu shortly before departure rather than relying on an older guidebook.

Altitude is the whole game

The walk from Lukla to Everest Base Camp is not technically hard. It is 5,364 metres high, which is a different kind of problem. Above Namche Bazaar the body is losing a race it cannot win, and the only genuine treatment is descent.

Gain no more than 400 metres in a day above 3,000 metres, take a rest day at Namche, and treat a headache that does not respond to water and paracetamol as a signal to go down tonight, not tomorrow.

Nobody argues their way out of altitude sickness. They only argue their way into it.

The villages

Namche Bazaar sits at 3,440 metres in a natural amphitheatre and is the social and commercial centre of the Khumbu — and where most trekkers first feel the altitude. Tengboche holds the region most important monastery, in a clearing facing Ama Dablam. Pangboche, Dingboche and Thukla follow.

The monastery at Tengboche and the smaller gompas along the way are working religious institutions. Entry usually involves a small donation, removed shoes, and no photography inside the prayer hall.

Wildlife, honestly

The park lists the Himalayan tahr, musk deer, Himalayan black bear, red panda and snow leopard. Tahr and the colourful danphe pheasant are commonly seen on the trail. A snow leopard is a once-in-a-lifetime sighting even for researchers.

When to go, and how long

The two reliable seasons are late March to May and late September to November. Winter is cold but clear and much quieter. The monsoon is dangerous: cloud, leeches on the lower trail, and unreliable flights into Lukla.

The standard round trip to Base Camp is twelve to fourteen days from Lukla. Add three days for acclimatisation if you intend to go above Base Camp to Kala Patthar.

Flights into Lukla are frequently delayed by weather. Build a spare day at each end of the trip.
