The Long Way Up: Trekking to Everest Base Camp Without a Guide

The permits, as they stand

• Sagarmatha National Park entry — around 3,000 NPR, obtainable in Kathmandu or at Monjo.
• Khumbu Pasanglhamu Rural Municipality permit — around 2,000 NPR, issued at Lukla or Monjo. This replaced the TIMS card for this region.
• TIMS card — no longer required for Khumbu, still required elsewhere. This causes constant confusion.

Acclimatisation is arithmetic, not attitude

Base Camp sits at 5,364 m. Kala Patthar, the viewpoint most people actually climb for the Everest view, is 5,644 m. At that height there is roughly half the oxygen available at sea level.

The rule that prevents most problems: above 3,000 m, do not increase your sleeping altitude by more than 300–500 m per night, and take a rest day every 1,000 m. "Climb high, sleep low" is the standard practice — walk up several hundred metres in the afternoon, come back down to sleep.

The standard itinerary builds in acclimatisation days at Namche Bazaar (3,440 m) and Dingboche (4,410 m). Do not skip them because you feel fine. Feeling fine on day four has no predictive value for day eight.

Recognising the problem

Acute mountain sickness starts as headache, nausea, poor sleep and loss of appetite — which is also what a hard walking day at altitude feels like, hence the difficulty.

The two conditions that kill are HACE and HAPE. The signs that mean descend now, tonight, without discussion:

• Loss of coordination — the field test is walking heel-to-toe along a straight line.
• Confusion or behaviour that others notice before you do.
• Breathlessness at rest, or a cough producing pink or frothy sputum.

Descent is the treatment. Not rest, not oxygen, not medication — descent. Five hundred metres down usually produces improvement within hours.

There is a Himalayan Rescue Association clinic at Pheriche with volunteer doctors who give free altitude talks daily at 3pm. Go to it.

The route, and the case for extending it

The standard is twelve to fourteen days round trip from Lukla: Phakding, Namche, Tengboche, Dingboche, Lobuche, Gorak Shep, Base Camp, then down.

Two extensions worth the extra days:

Gokyo Lakes and Cho La pass. Adds four to five days, takes you over a 5,420 m pass, and the view from Gokyo Ri is — most people who have done both say this — better than Kala Patthar. Far fewer trekkers.

Walking in from Jiri or Salleri. Adds five to seven days at low altitude. This is how everyone did it before the Lukla airstrip. It solves acclimatisation almost entirely, costs less, and passes through villages that see almost no trekkers.

Lukla, and the flight

Tenzing-Hillary airport has a 527 m runway on a 12% gradient ending in a rock wall. It is safe when flown in good conditions by the pilots who fly it constantly, and it is cancelled frequently — fog, cloud, wind. Delays of two to four days happen every season.

Build slack in at the end of your trip. People who booked an international flight for the day after their scheduled return are the ones paying 500 USD for a helicopter out.

What it costs

Independently, walking: teahouse bed 500–1,500 NPR (often free or nominal if you eat there), meals 600–1,200 NPR each and rising sharply with altitude, permits around 5,000 NPR, Kathmandu–Lukla flight 200–220 USD each way. Budget roughly 35–50 USD a day on the trail.

With a guide, add 30–40 USD a day; with a porter, 20–25 USD. If you hire either, verify insurance — porter insurance is a real issue and reputable agencies will show you the policy.

When

Pre-monsoon (March–May) and post-monsoon (late September–November). October is the clearest and the busiest. Winter is possible, very cold, and much emptier. Monsoon, June to early September, means cloud, leeches below Namche and no view.
