You will be picked up from your hotel in Kolkata for the 3-hour drive to the city of Kakdwip that is situated on the banks of the River Hooghly.
From Kakdwip a ferry boat will take you to Kachuberia on the island of Gangasagar. Vehicles are not permitted on the small ferry boat service. Upon reaching Kachuberia, another vehicle (non air-conditioned) will transport you to the beach-side of the island that faces the Bay of Bengal. The drive across the island takes around 40 minutes.
Spend the rest of the day relaxing on the beach. Enjoy lunch (beverage excluded) at a local restaurant.
Take time out to visit the nearby temple of Kapil Muni before your return drive to Kachuberia. Board the ferry at Kachuberia for the return trip to Kakdwip and the onward drive to Kolkata. On reaching Kolkata you will be dropped back at your hotel.
