The short answer
When to go to Mantralayam
November to February is the best window: dry, clear and cool enough for long queues and short river-side walks. March, and June to September, are workable but hot or wet, and the August Aradhana festival brings very heavy crowds. April and May are the hardest months, with afternoons around 40 degrees. For older travellers, plan weekday mornings and keep the afternoon for rest.
