Bhitarkanika National Park

Listen first. The engine of the boat drops to a low hum, and the water slaps softly against the hull. Somewhere in the green wall beside you, a kingfisher calls once, sharp and bright. The air smells of salt, wet mud, and something sweet and rotting underneath. The light here is never still. It flickers through thousands of leaves, and it breaks into small pieces on the brown surface of the creek. This is Bhitarkanika, and you are moving through one of the largest mangrove forests in India.

You are in the Kendrapara district of Odisha, on India's eastern coast. Here, the Brahmani and Baitarani rivers meet the Bay of Bengal. Before they reach the sea, they split into a maze of creeks, channels, and muddy islands. Twice a day, the tide pushes salt water deep inland. Twice a day, it pulls back again. Everything you see around you, every root and every animal, has learned to live with that rhythm of fresh water and salt water.

The name itself carries a story. Bhitarkanika roughly means inner Kanika. Kanika was a zamindari estate, a large landholding ruled by a local royal family. For generations, these forests were the private hunting grounds of the Rajas of Kanika. That protection, strange as it sounds, helped keep the forest standing. While mangroves elsewhere were cleared for farms and fishponds, much of this land stayed wild. So the forest you see today survived partly because of hunting.

Now look closely at the mud along the banks. Thin, pencil-like spikes stick up from the ground in their hundreds. These are breathing roots, called pneumatophores. Mangrove mud holds almost no oxygen, so the trees send roots upward into the air to breathe. Other trees stand on arching stilt roots, like legs lifting them above the tide. Each tree is a small engineering answer to a hard question: how do you live in salt, mud, and moving water?

The animals that made this park famous are the saltwater crocodiles. They are the largest living reptiles on Earth. By the middle of the twentieth century, hunting and habitat loss had pushed them close to disappearing from India. In 1975, a crocodile conservation project began here, with international support. Eggs were collected from the wild, hatched safely, and young crocodiles were raised before release. Today, the creeks hold one of the largest populations of these crocodiles anywhere in India.

Here is something many visitors do not expect. A crocodile resting on a mudbank can look almost lifeless. Its mouth may hang open for long minutes. This is not a threat display. Crocodiles cannot sweat, so they open their mouths to release heat. Watch the banks as the boat passes. That grey log in the sun may lift its head very slowly. Then it slides into the water... with barely a ripple left behind.

If your trip includes Dangmal, you reach the heart of the crocodile story. Dangmal is an island inside the park, and it holds the research centre and breeding work. Locals and forest staff often speak about a pale, almost white crocodile once kept here, a rare colour variation. Ask the guides what stories they share about it. Around the centre, you can also see enclosures and learn how the young reptiles are raised before they return to the creeks.

Crocodiles are only one part of the picture. Water monitor lizards, long and patterned, move through the mud like small dinosaurs. Spotted deer step out of the forest edge at low tide. Wild boar dig along the banks. Rhesus macaques sometimes watch from the branches above the water. And the birds are everywhere. The park is well known for its many kingfisher species, from tiny jewel-bright ones to larger birds with heavy red bills.

In the right season, one place inside the park fills with noise. It is called Bagagahana, a large heronry. Thousands of herons, egrets, storks, and cormorants gather here to nest. The trees turn white with birds. The sound is a constant clatter of wings, calls, and squabbling chicks. The smell is strong too. A nesting colony on this scale shows how rich the mangrove waters are. There must be enormous amounts of fish to feed so many young birds.

Now think about the coastline just beyond these creeks. Nearby lies Gahirmatha, a beach protected for its sea turtles. Olive ridley turtles come here in huge numbers to nest. On certain nights, many thousands of females crawl onto the sand together. Scientists call this mass nesting an arribada, a Spanish word for arrival. It is one of the few places in the world where this happens. The turtles depend on the same coastal waters that feed the mangroves.

This forest also protects the people around it. Mangroves act as a living barrier against storms. Odisha's coast faces powerful cyclones from the Bay of Bengal. Dense mangrove roots slow the waves and hold the soil together. Villages near healthy mangroves often suffer less damage than exposed coasts. For local fishing communities, the creeks are also a nursery for fish, crabs, and prawns. The forest gives protection and food at the same time.

The value of this wetland is recognised internationally. Bhitarkanika became a wildlife sanctuary first, and later a national park. It is also listed as a Ramsar site, a wetland of international importance under a global treaty on wetlands. But labels do not change the daily life of the forest. The tide still rises. The crocodiles still bask. The herons still return. Conservation here is a slow, patient story that continues today, season by season.

As your boat turns back toward the jetty, take one more moment. Look at the line where the water meets the roots. In a few hours, the tide will move again, and this view will change. The mud you see now will be under water, or the water will drop to show new banks. Listen to the engine, the birds, the soft splash of a fish. You are leaving, but the forest keeps its own time. It always has.
