The best time to visit Kedarnath is from May to June and September to October, when the weather is pleasant and the temple is open to pilgrims. The temple opens in late April or early May (Akshaya Tritiya) and closes around Diwali due to heavy snowfall. During summer (May–June), the skies are clear, the temperature is moderate, and the trek to the temple is accessible.
