Kashmir Great Lakes Trek is an absolute stunner spanning 7-8 days through alpine paradise. You'll hike 72km across mountain passes, camp beside seven gorgeous turquoise lakes like Vishansar and Gadsar, and walk through endless flower meadows at 11,000-13,750 feet. It's moderately challenging but totally worth it. Best time? July-September when everything's beautifully green. http://kashmirgreatlakestrek.com/
