The trek route to Torna fort is pretty much a straight route with couple of rock patches from Velhe the base of Torna. If you are planning your trek during or just after monsoons you would find couple of seasonal waterfalls enroute the trek route to Torna. Be careful to stay on course or else you might end up in the jungles around the fort. The rock patches towards the end of the route also needs to be negotiated carefully especially during monsoons as it would be very slippery.
