The short version: three of the most asked questions, answered in a line each. The rest of the page goes into detail.
- Where are the decision points on the crossing? The first is at Tilicho Base Camp: if anyone is unwell, return to Manang.
- What if I wake with a headache or poor sleep before the pass? Then the pass is not the right choice that day.
- How fit do I need to be for Mesokanto La? Trekkers who can walk comfortably for eight hours at 4,000 m are usually prepared.
How long do you spend at high altitude on the Mesokanto La day?
More than five hours above 4,500 m. The highest point is about 5,099 m, the day typically involves eight to twelve hours of walking, and there are no lodges or help close to the pass, so you need to be well acclimatised.
Where are the decision points on the crossing?
The first is at Tilicho Base Camp: if anyone is unwell, return to Manang. The second is at dawn: if the weather is poor, wait or retreat. The third is on the way up: if the pace is too slow to finish before dark, turn back.
What if I wake with a headache or poor sleep before the pass?
Then the pass is not the right choice that day. If you arrive at base camp tired, with a headache or poor sleep, returning to Manang is a perfectly good decision. Tell your guide early, rest, and do not push on because the schedule feels tight.
How fit do I need to be for Mesokanto La?
Trekkers who can walk comfortably for eight hours at 4,000 m are usually prepared. Those who struggle on normal Circuit days should not attempt it. Build endurance with long, hilly days and break in your boots and poles.
How cold and windy is the pass?
Dawn temperatures can be well below freezing, and wind at the pass can be fierce. Wear a base layer, fleece, down jacket and windproof shell, plus insulated gloves, a warm hat and a buff. Carry spare gloves and warm socks.
What emergency plan should I have for Mesokanto La?
Carry a charged phone, a first-aid kit and a plan for evacuation, and make sure your insurance covers helicopter evacuation. Mobile signal is unreliable, so ask your operator how they would call for help and how long a rescue might take.
Is late November a bad time to cross?
It carries more risk. Daylight is limited, nights are bitterly cold and early storms are possible. If you want the pass, aim for the stable weeks of mid-October to early November, and keep a spare day.
