Within that region, there are two national parks and two wildlife parks within close proximity. Minneriya National Park, Kaudulla National Park, Hurulu Eco Park and Galoya Eco Park are the four of them. Because of their large elephant herds, all four parks are extremely popular with locals as well as tourists from all over the world. 

Generally, each year during the months of July to October, large groups of elephants are found in the Minneriya National Park and Kaudulla National Park.  During the November to December due to high rains, lakes getting filled up. The Moragahakanda dam also fills the Minneriya and Kaudulla tanks, which supply water to farmers. 

At that period the grass (Elephants one of favourite food) on the edge of Minneriya and kaudulla tanks is sinked. Therefore, during the months of December and January, the elephants make their way to Hurulu Eco Park and Galoya Eco Park for the final leg of their migration in search of food. They will then remain in those parks until the end of May. 

Some of them migrate to Angammedilla and Wasgamuwa National parks.

As per the rain season changes, the elephant corridor migration behaviour periods may change.
