Rajmachi would be nice as it is winter and some pink cold weather. it can be done as a trek starting from the foothills or you can use the gypsys till rajmachi village on the top. campfires and star gazing can be done.
It completely depends what exactly are you looking for. If you're looking for treks you're at the right place, you would find forts with varying difficulty levels. Some of the well known forts are Sinhgad, Lohgad, Rajgad, Vishapur, Torna. Apart from that If you just want to enjoy your evening plan a visit for Lavasa city, Lonavala Tiger point. If you're looking for a historical place go for Aga Khan Palace, Shaniwar Wada & National War Memorial . Spare some time to visit Osho Garden Seven wonders dream park & Empress botanical garden too. Hope that helps😉
