Season at a Glance
Editor's Notes
September is the best overall month — flowers still present, skies clearer than July–August, mountain views sharper, and significantly fewer crowds.
The park opens June 1 every year without exception and closes mid-October. There is no trekking window outside this range — do not book without confirming your dates fall within it.
Peak bloom is mid-July to mid-August. If wildflower photography is your primary goal, plan for this window specifically — not just any month in the open season.
