The best time to visit in kashmir for a spiritual retreat or pilgrimage is during the spring and summer months (April to August). The weather is pleasant and conducive to meditation, temple visits, and peaceful reflection. Key pilgrimage sites like the Amarnath Cave, Shankaracharya Temple, and Hazratbal Shrine are most accessible during these months. For those visiting Amarnath, the Yatra season (usually from July to August) is particularly significant, but be prepared for a challenging trek.
