The journey from Jaisalmer to Jammu covers over 1100 km. The most efficient way is to take a train to Delhi and then a connecting train to Jammu Tawi. Alternatively, you can drive, but it is a very long journey. This route takes you from the desert to the northern plains and finally the foothills of the Himalayas.
Total Distance: 1150 km driving distance, 900 km straight-line distance.
Book your Jammu Tawi train well in advance.
September to March for pleasant weather.
