Hello there! There are quite a few places around Delhi that can be covered in 2 days. If you’re in the mood to visit hill stations, you can visit Shimla (Himachal Pradesh) and Nainital, Mussoorie, Ranikhet, Dehradun, etc. in Uttarakhand.
This is also a pretty good time to visit Jim Corbett National Park. Good Luck!!
Happy Travelling!!!
