This is where I started feeling the effects of the altitude: lethargy, nausea and a severe headache. Unfortunately, since we were short on time we ascended from 1950 to 4381 meters in two days and I ended up with some mild to moderate symptoms of Acute Mountain Sickness. Luckily, the next day we descended again (the full 2431 meters we had climbed the previous two days!). Three very long days of hiking, with incredibly beautiful views of the Langtang Mountains.
