This is a nice short pilgrimage trek which can be done without a tent during the pilgrim season (summer through september) I camped when I did it as it was late in the season and altready snowed over, but I was still able to stay with a friendly Sadhu by the lake. Its a pretty straight forward trek and since the path is used by millions of pilgrims finding your way shouldn't be a problem especially in season. Out of season can be more challenging because there are also some older paths that can be confusing and if things are covered in snow route finding tends to be more difficult in general, but in general still a pretty straight forward trek.
Scienic highlights include the spectacularly situated scared alpine lake that sits at the base of Manimahesh Kailash.
Cultrual highlights the pilgrims, sadhus, shrines, and offerines that are spread along the way to and shores of this sacred Hindu lake, and mountain.
