The journey from Yamuna Nagar to Mysore is a massive cross-country trip of approximately 2500 km. The most practical way is to take a train from Jagadhri to Delhi and then board a long-distance train to Bangalore, followed by a train or bus to Mysore. Air travel from Delhi to Bangalore and then a taxi to Mysore is the fastest and most recommended option.
Total Distance: Driving distance 2500 km, straight-line air distance 2000 km.
