Purulia-Adra route is way better in that case. You can get very light glance of Ajodha hills few miles before entering the city of Purulia. Joychandi Pahar can easily be viewed before entering Adra. Starting from Tulin, the whole route is very green and scenic. And yeah, I forgot about Adra, Bishnupur forest reserved areas. Bengali people or regular travellers on that route can describe you better.
