Leh - Srinagar
A moderately difficult route through the heart of Ladakh that offers sublime views of snow covered peaks during the summer, and roads as clear as the weather in the winter. I did this through the first two weeks of October, 2016 and highly recommend it if you are an experienced cyclist.
Road conditions are excellent for the most part, however, be warned, carry spares and be careful when descending Zoji La pass on the way to Sonamarg.
Leh to Srinagar is far easier than Srinagar to Leh.
