Rashol is a small village in Parvati valley of Himachal Pradesh. This is one of the best things to do if you are in Kasol. From Kasol it is an 8KM trek to Rashol and will take approx. 5-6 hours depending on your speed. There are multiple cafes where you can eat and smoke on the way. There are no. of stay options at the top like hotels and camps. You can get one room in Rs500 for two persons. One most important thing to remember if you are on any trek: Always enjoy the trekking rather than asking every minute "when we will reach or How much is left".
One best thing you can do after reaching Rashol is you can trek to Malana Village directly from Rashol without coming back to Kasol.
