Hi Umang, from pune you will have access to a lot of different kind of locations. You can head to Rajasathan or Gujarat, you can visit Udaipur, Jaisalmer, Mount ABu or The Great Rann of Kutch. Visiting Diu is another option for you, it is an offbeat and less explored location. Also you can head to trek in many of the location in Mahrashtra like Rajmachi and Matheran. Another option is hitting the coastal belt, Hampi, Gokarna or any place in Goa.
If you are looking for some adventure and fun you must check out Bhandardara, dist. Ahmednagar, Maharashtra. It's an amazingly beautiful place. There are mountains all around. Bhandardara is situated in the midst of Sahyadri range. You must visit this place once at least.
