About Kolkata

Between its stunning Raj-era architecture and iconic coffee houses, Kolkata is basically a living time capsule of literature, politics, and art. Sitting by the Hooghly River, the city’s been a major trade and intellectual hotspot ever since the colonial days.

When to Plan Your Trip

October to March is the ideal window to hop on a flight to Kolkata: pleasant temps, clearer skies, and festive buzz, especially during Durga Puja when the whole city turns into an open-air art gallery. April–June can get hot and humid, often hitting 35°C+. Come June–September, monsoon brings lush, cinematic greens, but expect some waterlogged streets here and there.

Airlines, Airports & How to Get There

Flights to Kolkata arrive at Netaji Subhas Chandra Bose International Airport (CCU) in Dum Dum, about 17 km from central Kolkata. Airlines like IndiGo, Air India, and SpiceJet keep the route map busy, with regular flights to and from Kolkata, linking it with big hubs like Delhi, Mumbai, Bengaluru, Chennai, and Hyderabad. You’ll also find a few international routes from here to parts of South/Southeast Asia and the Middle East.

What to Do in Kolkata

Once you’ve booked your flights to Kolkata, start prepping the itinerary with top highlights like Victoria Memorial, an iconic marble landmark-cum-museum, Howrah Bridge, one of the world’s busiest cantilever bridges, and Dakshineswar Kali Temple, a major pilgrimage site. Finish it off with classic Kolkata experiences like tram rides, river ferries on the Hooghly, and a wander through the Indian Museum if you want a deeper peek into the city’s past.

Festivals of the City: From Durga Puja to Derby Day

Nothing captures Kolkata’s festive spirit better than the five-day spectacle of Durga Puja. In Bengal, Durga is the beloved daughter who returns to her parental home once a year with her children (Lakshmi, Saraswati, Kartik, and Ganesha) for a short autumn stay.

Neighbourhoods go all out with themed pandals, artists create stunning idols of the goddess, and whole streets light up with music, lights, and endless food stalls. When the idols are finally immersed in the Hooghly River on the last day, it symbolises Maa’s return to her celestial home until the next year.

But Kolkata’s festive spirit doesn’t end with religion; it continues in stadiums. Football rivalries here feel almost mythic, especially when historic clubs like Mohun Bagan Super Giant and East Bengal FC face off in the famous Kolkata Derby. 

For cricket fans, Eden Gardens is basically sacred turf. The iconic stadium is often dubbed the “Mecca of Indian cricket,” and it’s seen some of the most legendary matches the sport has ever had.

The Flavours and Nightlife of Kolkata

Kolkata’s food culture is elite, from kathi rolls and biryani to mishtis like rosogolla, with nightlife and cafés buzzing around Park Street and Elgin Road. For bargain hunting and souvenirs, New Market remains a classic. The city also hosts major book fairs and film festivals, giving it a strong cultural pull.
