Sultanpur National Park

Coringa Wildlife Sanctuary spreads across the Godavari estuary near Kakinada, where India's second largest river meets the Bay of Bengal. Covering 235.7 square kilometers, it holds the country's third largest mangrove stretch, behind only the Sundarbans and Bhitarkanika. And unlike those two, you can boat straight into its green tunnels any morning.

The sanctuary came into being on 5 July 1978 under the Andhra Pradesh Forest Department. Since then it has grown into one of coastal Andhra's most rewarding nature escapes, part nursery for fish, part bird airport, and part crocodile country.

What Makes Coringa Different

Mangroves here stand on stilts. Their tangled prop roots lift the trees above tidal water that floods the forest twice a day. Those roots trap sediment, slow storms, and shelter baby fish by the million. Local fishermen will tell you the sea's wealth starts in these creeks.

Twenty four mangrove tree species grow here. That variety matters because each species feeds a different web of crabs, mollusks, and birds. Add more than 120 recorded bird species and you get one dense, noisy ecosystem.

The Wildlife You Might Meet

The star is the fishing cat, a stocky, water loving feline that most visitors never see and everybody hopes to. Coringa celebrates it with a sculpture of Macha, the sanctuary's famous fishing cat, at the entrance. Otters patrol the deeper channels too, though their numbers have suffered from poaching over the decades.

Saltwater crocodiles once vanished from these waters, then returned through a Forest Department reintroduction program started back in the late seventies. Sightings happen on quiet creek bends, usually just eyes and snout above water. Keep your hands inside the boat. Seriously.

Birdlife steals the show from October to March. Painted storks, open billed storks, egrets, herons, flamingos further out on the mudflats, and both the critically endangered white backed and long billed vultures somewhere in the canopy above. Bring binoculars or regret it later.

Things To Do at Coringa

Take the boat safari. Motorized boats run from the Kakinada side into the creek network, gliding under arches of mangrove roots. Morning slots offer calmer water and active birds.

Walk the wooden boardwalk. An elevated walkway carries you dry shod into the forest interior. Look down for mudskippers, fiddler crabs, and kingfishers using the roots as perches.

Climb the watchtower. The viewing tower opens up the whole estuary panorama, Godavari channels braiding toward Hope Island's sandspit offshore.

Visit Hope Island. This natural sandbar shelters Kakinada port from cyclones and forms part of the sanctuary's seascape. Boats combine the island with mangrove circuits on fuller trips.

A Simple Day Plan

Start early from Kakinada, reach the sanctuary gate by 9 AM when it opens. Do the boardwalk first while the light is soft and crabs are busy. By 10:30, hop onto a boat for the creek circuit.

Lunch back in Kakinada, famous across Andhra for its seafood. Prawn curry here is a religion. Afternoon suits the watchtower and a slow drive along the Yanam Kakinada road, watching the delta villages go by.

Food, Fish, and Delta Life

Kakinada's kaja sweet travels well, so buy a box for the road. Around Ramachandrapuram and Amalapuram, roadside stalls sell fresh coconut water and hot mirchi bajji that pairs perfectly with estuary breezes.

The delta runs on aquaculture and rice. Fish ponds flash between paddy fields everywhere you look. It's flat, green country, best enjoyed slowly on a two wheeler with no particular schedule.

The Conservation Story

Coringa faces real pressure. Fuelwood cutting, aquaculture expansion, and fishing have squ
