Make sure you take plenty of rest and get acclimatized to high altitude. Some of you make feel acute mountain sickness (AMS), short breath, headache, nausea etc. Drink enough water, do not go on higher altitude for atleast 24 hours and dont forget to carry Camphor with you to help you breathe in case you feel out of breathe. Some medicines also may help you but consider them only after a consultation with your physician.
Ladakh is full of wonders..Its amazing what you can see if you know where to look..the mountains, the dessert, the valleys, the rivers and the monasteries. I never thought I would choose this over any other luxury escapes. It was my 1st solo trip immediately post PG exams. I explored other side of me. It was worth it!
