On April 1, the trek "To the Heart of Annapurna" (Nepal) starts. At this time, rhododendron forests bloom in the Himalayas. This is an indescribable spectacle. The jungle is completely covered with bright red flowers, birds sing and streams gurgle. And all this in order to convince you to come and see spring with your own eyes in the Himalayas :)
The second argument for traveling to Annapurna in April is that this period is sparsely populated compared to autumn or the May holidays.
