Hey there i am a local tour guide as well recently o took the groups to kheerganga it is not safe now as it is raining but you can on oct the weather will be pleasant
Yes ,u can go no doubt but it is best to travel kheerganga in the end of july but u can also go in September.The trek's gonna be slippery and there will be cold at top ,usually the temperature in june is 1-4°C so you should be properly prepared with your winter layerings and be sure to take rain layerings bcoz the weather changes too quick .Take extra pair of shoes with you if u don't have waterproof shoes bcoz there are many small waterfalls during the trek and it will make your feet wet .So be sure to take all the necessary things with you.Take dry fruits during the trek as it will give u the energy throughout your trek.
The best time for the Khirganga Trek is from May to June and September to October. So, you may plan your trek in any of these seasons. You will find a large number of spots for camping during the Kheerganga Trek route.
