So to sum up the cost of this trek:
Train= CST - Khopoli (return)= Rs. 60
Bus= Khopoli - Pali (return)=Rs. 102
Bus= Pali - Bhira Village (Return ) =Rs.40
Total expenditure=Rs. 202.
Guide Cost(A localite) = Rs.100 ( when I went it wasn't compulsory)
So now your expense would be Rs.300 for the whole trek. Like my page on Facebook to know my upcoming adventures : Trekraw
