The first day trip begins with the iconic Krishnanagar Cathedral. It is one of the largest churches in the district of Nadia, West Bengal. Alongside the church, you can see a monument made in the shape of the Roman Catholic Church, which is named as "Christo Mandir". The Christo Mandir has some beautiful architecture inside, depicting scenes from the holy Bible. Along with it, there is another monument, in a stepped form, with beautiful architecture, depicting scenes from the holy Bible again. The place is not so congested too, except during Christmas and New Year. If you love architecture, then you shouldn't miss it at all.
At the boundary of Krishnanagar there is a river named Jalangi , which is a tributary of River Padma of Bangladesh. It has a great scenic beauty around and sitting at the banks of River Jalangi is indeed a great pleasure. There are 3 bridges crossing the river, one for road and the other two for rail. This Jalangi River is best viewed from Deluxe Brick Field Ghat, nearby.
About a 30 minutes drive away, from Krishnanagar is the village of Bethuadahari, which houses the Bethuadahari Wildlife Sanctuary. If you are someone, who loves nature, you simply cannot afford to miss it. You can see, deers roaming around freely over here, along with other animals like Nilgai, Painted Stork, Peacock, Gharial, Turtles , a few other birds and trees and plants of various species.
On your way out, you can see the Forest Bungalow, which has several models of the places to visit, nearby Krishnanagar. It also has preserved pigeon eggs and crocodile hatchling, put up for demonstration.
A Krishnanagar visit is totally incomplete without having a look at the Royal Palace of Krishnanagar, which belonged to King Krishna Chandra Roy, after whom the township of Krishnanagar is named. Although, you will not be allowed to enter the premises of the palace, the main entrance, colloquially known as "Singhodwar" is worth seeing.
However, you can enter the palace premises on two separate occassions in a year- The Durga Puja and the Jagadhatri Puja. It is worth mentioning that it was in this royal palace, where Jagadhatri Puja had first taken place.
