This trek can be done in two – either in May-June which is just before monsoons or August – September which is after the monsoons. Now if you chose to do the trek in May/June, the bugyals will be greener than ever and the lake will be thawed which means you get to see the skeletons. However, there won’t be much snow on the trail during this time.
