Acclimatization
The 9-day Langtang Gosaikunda Trek isn’t an extreme elevation trek. Thus, you don’t need acclimatization during this trek. However, if you want an acclimatization day, it’ll be at Kyanjin Gompa.
Starting from Syabrubesi, you’ll trek for three days to reach Kyanjin Gompa, with short day walks and adequate rest.
Langtang Valley is below 4000 meters unless you decide to climb Kyanjin Ri and Tsergo Ri. On the day you reach Kyanjn Gompa, you’ll settle in at the tea house for a day. The hike to Kyanjin Ri or Tsergo Ri will be on the next morning. Also, on the day from Langtang to Kyanjin, you’ll only trek for three hours. Thus, spending an entire day at the tea house in Kyanjin provides you with adequate rest and acclimatization, should you plan to climb Tsergo Ri or Kyanjin Ri.
By the time you complete Langtang Valley Trek and return to Thulo Syabru, your body gets well acclimated. Thus, trekking to Lauribinayak and Gosaikunda Lake won’t be an issue. You’ll complete the remaining Gosaikunda Trek without getting altitude sickness.
