The short answer
When to go to Koyna
November to February is the best window: cool, clear and open for boat rides and forest treks. March is workable if you start early; April and May are hot, and the lake falls, shifting landings. From June to September the monsoon brings very heavy rain, green slopes and waterfalls, but the Vasota area is closed from about mid-June to mid-October. Older travellers should prefer winter for the dam and lake, and avoid the treks.
