The entire route passing through Hills and River and its treat to make small pit stops. There is one river crossing at Bhatghar Dam. The spot is worth stopping by and to soak in serenity and Peace it offer.
Finally if you are still left with time, you can head towards mahad. (the road is not in great condition though).
You will reach small place called Nirgudaghar. (its so small that you wont find it on google maps also.) Search for Apti. This place is after Apti. Leave Mahad highway here and go inside. This will take you on the back side of hills.
(Warning: The road is single road and offers very low visibility. Its regularly turning so exercise extreme caution when Driving)
Drive for 20 odd mins and you will reach at the base of rayaeswar fort. You get to see Nira Deoghar dam from here.This should be good enough to call it a day and head back to pune.
