Kheerganga used to be haven for trekkers and fun-mongers alive, mostly due to shopsa and dhabas that had conveniently sprung up to support the increasingly large crowds it had begun to attract. However, recently, the government of Himachal Pradesh has, due to valid environmental concerns, shut down illegal shops. Also, one has to now take prior permissions from the forest department before embarking on a trek. It is better that you go with organised groups who can arrange it (permits, accommodation, food, etc) for you rather than a solo sojourn.
Kheerganga doesn't have any crowd as of now because of the ban imposed there and it's completely isolated. my best suggestion for you would be McLeodganj-Triund. Trek to Triund -Snowline- Laka Glacier and have an amazing experience.For any further queries or itinerary, contact me or message me.
