So here’s the thing, Tibet is way, way high. Crazy high. Everyone knows that to trek in the Himalayas you’ll have altitude issues and probably need to take diamox and have acclimatisation days and such like, but before we set off to Tibet last week I hadn’t actually thought much about the altitude of the Tibetan Plateau. The altitude of the passes you will cross to likely get to Lhasa are off the scale. So here’s some information for you on altitude in Tibet.
Altitude in Lhasa
Lhasa is at 3660 m ( 12,007 feet) so that’s not a massively big deal. It’s high, sure, and you’ll be out of breath walking up stairs. You may have a killer headache too, but it’s not so high that I’d be panicking.
Lhasa is quite low by Tibetan standards so this is not the place I’d be worrying about.
Tibet’s High Passes
We drove to Tibet and in going this way, by road, we went over 4,000 and 5,000 m several times. This is where we really felt the altitude all be it for just a few minutes while we leapt out of our luxury bus to take tourist happy snaps.
It is incredibly hard to accurately name these passes. At the time we crossed them we presumed it would be easy to check names and heights later using Google maps. unfortunately, due to the Chinese Google and Social Media Ban we’ve been unable to find accurate names for these passes. This is further complicated by names being in Chinese, Tibetan and Nepali. We’ve done our best.
Yela Pass or Zhongma in Shigatse. The First Pass We Crossed from Nepal 5236m
Because of the 2015 earthquake causing extensive damage in Nepal and Tibet, road traffic from Nepal to Lhasa is currently taking the route above. This pass was the first high point on our journey from Kathmandu to Lhasa and came after a switch back climb or hairpin bends.
Don’t be alarmed, roads are quiet in Tibet, vehicles good and driving well controlled. This is not the case in Nepal, over there you take your life in your hands getting in a bus.
This pass was well before we joined the Friendship Highway, which is the usual route from Nepal. We joined this famous road ( which goes all the way to Shaghai) later on day 2.
This was the highest pass we crossed and we all felt its effects sharply, but only when we were out of the bus walking around to take photos. It was at at 5236 m and was the highest of the whole trip.
Simila Pass, 4,200m
This one is above the man-made lake at the Manla Reservoir. It’s a nice photo stop and not breath-takingly high.
Gyatso La Pass 5220m
At an elevation of 5220 m the Friendship Highway runs through the Gyatso La Pass.
Gawu La Pass, 5,198 m
Another mountain pass on the way to the Everest Base Camp. Other mountains in the region above 8000 m are Mt Shishapama, Mt Lotse, Mt Makalu, and Mt Cho Oyu,
Should You Take Diamox for Tibet ?
I just need to say ( for legal reasons) that nothing I have to say is medical advice and should not be taken as such. I’m just a mum who’s done a bit of high altitude trekking with and without Diamox, with kids. I also used to work in medical science so I understand long words like diuretic and respiratory stimulant.
Diamox is both of those things. It helps you cope with altitude but it can make you pee.
The making you pee part was a major problem for us because the toilets outside of our hotels were absolutely rank and nobody wanted to use them.
As on our Everest Trek the month before, we started taking Diamox as a preventative and stopped after a few days when we’d had enough of public toilets.
You can easily buy Diamox, without prescription at a pharmacy in Kathmandu. It costs a couple of dollars for a pack of 10 and as a preventative you normally take half in the morning , half at night.
Some people like to get Diamox on prescription from their GPs in their home countries.
Only once has any of us taken a whole Diamox tablet. My husband had a headache at Gorak Shep ( near Everest Base Camp, Nepal side) so I made him take one. He had to get up and pee 14 times in the night and wasn’t best pleased with me.
Of course, good hydration is supposedly vital for proper acclimatisation and avoidance of altitude sickness. The more you pee the more you need to drink, the more you pee. This isn’t great.
“They” whoever they are, say you should drink 4 L of water a day at altitude. We have never got anywhere close to that and nobody has died or had AMS. Including the kids. But you should drink. The Tibetan Plateau is a high cold desert and it sucks the moisture out of your body alarmingly fast. Take a good lip balm with sun block, something like this.
Some people say that Diamox makes your fingers and toes tingle. Maybe it does, but I find I get the hypoxia tingles without the Diamox too. Usually when my extremities get a bit cold.
Do what you feel is right for you. A ” suck it and see” approach is always my best friend. When you’re trekking in the Himalayas the advice is always to go down if you feel altitude problems coming on. This isn’t easy in Tibet, so yes, altitude can be a worry.
