No matter how short the trekking duration is, you're likely to get altitude sickness if you're hiking above 3000 meters. So, it's crucial to take your time acclimatizing if you want to have a safe and enjoyable trek. Your body requires time to adjust to the shifting altitude in between ascents and descents. The most efficient strategy to prepare your body for abrupt altitude changes is to acclimate for a day. So, we have included a rest day at Kyanjin Gompa in our Langtang Trek 8 Days itinerary.
