At this point, our guide did a stupid thing. He asked us to climb up straight so that we can cover more altitude in less distance and approach to lake will be easy.
But when we climbed up, he took us down to mini lake and we were again at same altitude where we started 
This meant that we had to do a big climb again till main Ratti Gali Lake.
I realized this mistake when we were climbing up for the main lake again as a trek was running all the way to the main lake from the point we started coming down to mini lake.
And i was like @#!$@^^%@
Climbing up on very steep angled slope with style of locals ... zigzags of 4-5 steps right n left.
