Experience of a lifetime!!! Excellent guide & food was incredible! Pack warm for the night. May be coldest nights I\’ll ever endure (I hope!), I wore everything I brought and still freezing. Tough trek but more rewarding than anything I\’ve done. Not sure if it was the cocoa tea they served every morning and night, but I did not have any problems with altitude. My best friend who came with me did but it was over in a day. Totally worth it regardless! Good luck in your travels!! It will definitely be one of the best trips of your life!!!.
