*Another name of Minto Park is Shahid Bhagat Singh Udyan.
*Take a cab from Airport and tell the driver to take you there. It's a well known place, he should know the direction. If not, go in this direction:
Airport- VIP Road- Ultadanga- EM Bypass- Parama island- JBS Halden Avenue- Park circus (Drive should know this place)- Circus Avenue (Don't take the flyover)- Minto Park.
Opposite of Minto Park, there is a road named Sarat Bose Road.
*If you want to take public transport system:
Take Em Bypass- bound bus (ask if going to Parama island) and land there, Then take Auto- rickshaw or bus (if available, obviously after asking other people) for Park circus. After that, take a bus again if the last commuting vehicle does bot go up to Minto Park.
*Another route: Take bus (routes are 237, 46 etc) up to Girish Park. Catch metro train go to Rabindra Sadan. Then just walk towards Minto park/ Gorky Sadan.
*Whenever in trouble in finding destination or route, ask any local people.
*From Airport- Minto Park in a cab will cost you rs. 300 (at least, I think as its longer than 15 km).
