Although mussoorie is a beautiful hill station to visit all year round, I personally would recommend that you travel in the months of April and May and October to March to experience beautiful winter season
March till June are the best months to visit Mussoorie for a pleasant sightseeing tour and to enjoy the spring and flower bloom and cool summers. Visitors can avail of the cable car ropeway ride to Gun Hill, which offers a captivating view of the surrounding Himalayan Mountains.
