The Khayar Lake trek program is designed in such a way as to allow full acclimatization to prevent anyone from getting AMS (Acute Mountain Sickness). When trekking in the high altitude, the general rule is to keep a slow pace allowing the body enough time to adjust to the height being gained every day. The higher the altitude, the less is the oxygen in the air and our body needs to adjust to this accordingly.  It is therefore essential that we allow you sufficient time for acclimatization.  Since this trek gains a maximum height of 4827m, it is likely that some of us who are not used to high altitude hikes may be affected by it. And in order to avoid this we have planned our itinerary by keeping the initial days of walking moderately within limits and by providing plenty of time for proper acclimatization.  If you are concerned about it in anyway or just like to find out some useful tips on altitude sickness when trekking, then please refer to “Altitude illness” by Dr. Jim Duff who has provided detailed information about altitude sickness and the ways to prevent them.

Preventing altitude sickness when trekking in Nepal:

• Ascend slowly to altitudes above 2500m.
• Take 48 hours to acclimatize when ascending above 2500m.
• Avoid alcohol or sleeping pills
• Drink plenty of water or herbal tea (no alcohol or coffee)
• The altitude at which you sleep should normally be no higher than 300m than your sleeping altitude of the previous night
