Ballygunge is served directly by Ballygunge Junction railway station (Sealdah Main Line, opened 1862, about 6 km from Sealdah, 150+ daily EMU pairs) and nearby Park Circus station, plus metro access via Jatin Das Park, Kalighat, Netaji Bhavan and Rabindra Sadan stations (Kolkata Metro Blue Line).

Arterial roads - Gariahat Road, Ballygunge Circular Road, Hazra Road and Ashutosh Chowdhury Avenue - connect to the AJC Bose Road/Maa Flyover corridor toward EM Bypass and Park Circus, with WBTC buses covering the rest of the city.

Ballygunge hosts the University of Calcutta's Ballygunge Science College campus on Ballygunge Circular Road, alongside reputed schools such as South Point High School, St. Lawrence High School, Patha Bhavan, Ballygunge Government High School, Army Public School and Kendriya Vidyalaya (Ballygunge Maidan Camp).

Basanti Devi College, Muralidhar Girls' College, National High School and Jagadbandhu Institution add to a dense, largely walkable education cluster serving South Kolkata families.

Ballygunge has no manufacturing base; its economy centres on the Gariahat retail-trade belt along Rashbehari Avenue and Gariahat Road - one of Kolkata's largest markets for saris, jewellery and electronics - plus professional, healthcare and education services.

It lies a short drive from the traditional Park Street-Camac Street business district, while the Salt Lake Sector V/New Town IT corridor is considerably further, making Ballygunge more a commercial-residential address than an industrial or office-park hub.

Ballygunge is home to the marble Birla Mandir (Krishna-Radha temple built by the Birla family, consecrated February 1996) on Ashutosh Chowdhury Avenue, and lies minutes from the 192-acre Rabindra Sarobar lake and park. During Durga Puja its Ballygunge Cultural Association pandal draws over a million visitors daily and joins the state's Red Road immersion carnival, alongside the acclaimed Ekdalia Evergreen Club pandal.

Kalighat Temple, Victoria Memorial and the Indian Museum all lie within about 3.5-4.3 km.

Gariahat Market's shops, eateries and street-food stalls anchor daily life, supplemented by Gariahat Mall (Westside, Spencer's) within the locality. Quest Mall - with an INOX multiplex, Spencer's Hypermarket and luxury retail - sits just across the Ballygunge-Park Circus boundary on Syed Amir Ali Avenue.

Tree-lined avenues, old clubs and cafes along Ballygunge Circular Road add to a lively social scene, and Durga Puja turns the neighbourhood into one of Kolkata's biggest festival hubs.

Ballygunge spans KMC wards 65, 68, 69, 85, 86 and 90 under Borough VIII, with roads, drainage, water supply and parks managed by the Kolkata Municipal Corporation. Key roads include Ballygunge Circular Road, Hazra Road, Gariahat Road and Ashutosh Chowdhury Avenue.

Housing ranges from 1930s-40s heritage mansions to new apartment towers, backed by established hospitals (Duncan Gleneagles, SSKM nearby) and schools, though residents flag ageing drainage and monsoon water-logging in some lanes.
