Hi Priya! The Sinhagad trek is not very difficult and is do-able for amateurs. For a regular trekker, it would hardly take 40 minutes to complete. The trek can be visited at any time of the year. You can check out these trips for more information and details!
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.
