If you are palced in Southern part of India Munnar will be the best choice can opt Goa too but it will be very hot in the day time. For north India there are plenty of choices Simla. Nainital , Mussouree etc. Eastern part of India can try out Arunachal Pradesh Tawang. Bomdila dirang or simply Kalingpong My favourite is hills so my suggestion you may find bit inclined. Best of luck and happy touring.
