The best way to go to Shikari Devi, in my experience is by bikes. The road from Janjheli to the foothill of Shikari Devi, is not just challenging, its the whole package. Once you are there you'll have to climb up 602 stairs( i know the exact number, because we counted it). Once you are there, you'll be blown by the beauty of those hills. You can see as far as Shimla from there. There aren't any places to stay there except a Forest guesthouse, which you need to book in advance as they only have three rooms. If you dont want to stay there, or if the trip was impromptu and you haven't booked at the guest house, you can always come back to Janjheli. They have a few decent guesthouses, ranging from INR 300 to INR 700.
