Hello and welcome to the forum!
The distance between
Kolkata and Sundarbans is about 114 kms. There are
several transportation options you can take:
1.
Buses - I think this is the best public transportation option to reach Sundarbans. From Kolkata, go to the Babu Ghat Bus Terminal (West Side of Eden Garden) and ride a bus going to Sonakhali. This is about 94 kms so you can reach Sonakhali in 3 to 4 hours.
Here are some of the bus timings I was able to find:
- 6:00, 7:30, 7:45, 9:15, 10:45, 11:00, 11:45, 13:00, 13:30, 15:15, 16:30 and 17:00.
Then, from Sonakhali, ride a rickshaw to reach Godkhali. You can then ride a direct boat from Godkhali to Sajnekhali. Otherwise, your other option from Godkhali would be to take a boat ride to Gosaba, then ride a cycle rickshaw to Pakhiralay Village and then take another boat ride to Sajnekhali.
2.
Trains - You need to go to the Sealdah Railway Station in Kolkata. From there, ride a train going to the Canning Train Station. Some timings I was able to find are:
- Sealdah Canning Train No. 34512 - Departs daily at 5:45 and arrives at 7:08.
- Sealdah Canning Train No. 34514 - Departs daily at 6:30 and arrives at 7:45.
- Sealdah Canning Train No. 34516 - Departs daily at 7:42 and arrives at 8:55.
The last train is at 23:18 and there's a train almost every hour departing from Sealdah. From Canning, you can ride an auto rickshaw or shared vehicle to go to Godkhali. Then, you have the same options as above. These are unreserved trains though so you might have difficulty riding them.
3.
Taxi - You can ride a taxi from Kolkata to Godkhali. Fare ranges between Rs. 2,000 and above. From Godkhali, you have the same options as above.
Now, let's go to
Gangasagar, which is about 106 kms from Kolkata. Here are your
transportation options:
1.
Buses - This is you best option as well. From Kolkata, ride a bus from Esplanade going to Kakdwip and drop-off at Harwood Point or Namkhana. You can find CSTC or WBSTC Buses from the station. Some bus timings I was able to find are:
- Kolkata State Buses - Departure from Kolkata: 9:00 am, 10:15 am, 12:30 pm and 4:30 pm.
- Namkhana SBSTC - Departure from Kolkata: 6:00, 6:30, 7:00, 7:30, 8:00, 8:30, 9:00, 9:30, 10:00, 10:45, 11:00, 12:00, 13:15, 14:30, 15:00, 15:30, 16:00, 16:30, 18:30 and 19:30.
From both Harwood Point and Namkhana, you can ride a ferry service going to Sagar Island. Ferries are more frequent in Harwood Point though with one bus every half hour.
2.
Trains - Go to the Sealdah Railway Station and ride a train going to Kakdwip Station. These trains are unreserved as well. Some timings are:
- Sealdah Namkana Train No. 34792 - Departs at 13:20 and arrives at 15:41, runs daily.
- Sealdah Namkana Train No. 34782 - Departs at 20:30 and arrives at 22:56, runs daily.
- Sealdah Namkana Train No. 34794 - Departs at 21:30 and arrives at 23:56, runs daily.
From Kakdwip Station, ride an auto or manual rickshaw to Lot No. 8 Ferry Ghat. You can then ride the ferry to Sagar Island.

Taxi or Hired Vehicle or Car - You can take the Harbour Diamond Road to reach Lot No. 8 Ferry Ghat. Cars or taxis are allowed to park in Panchyat Samity.
I hope this helps!
