Why is Gahirmatha Marine Sanctuary Famous?
The sanctuary is internationally recognized because it protects the largest mass nesting site of Olive Ridley sea turtles.
Every year, millions of turtles migrate thousands of kilometres across the Indian Ocean before returning to Odisha’s coast for breeding and nesting.
This incredible natural phenomenon is known as Arribada, a Spanish word meaning “mass arrival.”
It is one of the rarest wildlife events in the world.

Gahirmatha lies along Odisha’s northern coastline in Kendrapara district, stretching:
- From the mouth of the Dhamra River in the north

What is Arribada?
The World's Greatest Turtle Gathering
Arribada is the synchronized nesting of Olive Ridley turtles.
Instead of nesting individually, hundreds of thousands of female turtles arrive together, making Gahirmatha the world’s largest nesting beach.
This synchronized nesting greatly increases the survival chances of hatchlings against predators.
