The trek to Kheerganga starts from Barshaini and Tosh.
You first need to get to Bhunter and then from the to Tosh -
Getting to Bhunter - From Delhi getting to Bhunter takes 14 hours approx. Start from the ISBT Kashmere Gate, you can reach the ISBT via metro, auto, bus or taxi from prettymuch anywhere in Delhi.
Getting to Tosh - From Bhuntar it is a 4 hour bumpy bus ride that shouldn't cost more that 100+ Rs or a Taxi that should take 1000 to 1200 Rs. Now when you take the bus it will only take you upto Barshaini (Bar-che-ni) from where you will have 2 options, take a cab that will cost 200 Rs or walk for around an hour across the hills to get to Tosh. Walk, trust me, Walk.
The trek is 14-15 kms long and is an easy walk in the park for the first 7 kms but after you cross the first dhaba the trek can become a little more demanding especially if you are carrying a bag or if it rains, which in my case was both.
Kheerganga has plenty of places to stay and accomodation is rarely a problem.
The rates may vary from 500 Rs a night to a mere 100 Rs a night at the 'Ashram' built on top.
You can chose from brick or wooden houses to tents depending upon how much time you want to spend inside a room in beautiful valley and how comfortable you want to sleep at night.
One can even carry there own tents and set them where ever they wish to which would save a lot on accomodation expenses, only if you're there for more than a week though.
As it is in most of Himachal, there's many foreign tourist in Kheerganga and one can find a variety of cuisines over there.
Moderate price and alright taste would give the cafe's of Kheerganga 3 out of 5 stars.
The one thing you'd love to do there is just sit and sip hot drinks, tea, coffee and other things people prefer consuming hot are the biggest sellers at all the cafes.
Many people travel to Kheerganga as it has a temple of Lord Shiva and Goddess Parvati and the hot water spring there is considered to have medicinal properties. The night sky that gives you a panoramic view of the outer milky way a treat you must not miss.
