Howrah official is a city on its own but in fact it has long grown into one huge city together with Kolkata. Howrah is located on the Western bank of the Hooghly river. Generally Howrah is considered less modern than the Kolkata side.
To zip around between Kolkata and Howrah the ferry service to cross the river Hoogly is very good. There are a number of Banks (on the other side) and the ferries go to such as Armenian, Fairlie, Chandpal, Babughat, Princep. The fare per head is Rs 4, buy the ticket before you board the ferry and retain the ticket till after you have crossed to the other side and have shown it to the ticket checker near the Exit gate or else you will be fined!
Belur Math, Northern part of Howrah (about 4 km from Howrah railway station. You can travel there by bus, auto or taxi. It takes 20-25 mins to get there and around 40 mins to return, because this route is longer and becomes more congested. All modes of transportation are easily accessible from adjacent to the Howrah railway station area/Howrah bus stand. Local trains also go th Belur Math, but going by auto, bus or taxi is much better as they drop you off at the entrance of Belur Math.). It's a worthwhile visit. Situated next to the Ganges one can sit on the banks of the river Hoogly during evening time and relax. Across the river Hoogly is the Dakhineshwar Temple. A visit to the temple is free and so is parking.. edit

Santragachhi Jheel, Middle part of Howrah city (7 km from howrah station by train, or 6 km from kolkata via Vidyasagar Setu). Santragachhi Jheel is a large lake, located next to the Santragachhi railway station. This lake attracts large number of migratory birds in the winter months, particularly in December and January. The number has increased in recent years, as migratory birds have started to avoid destinations like the lakes in Alipore Zoo, Kolkata. Birds like Saras Crane from North America and Australia, and many other local migratory birds such as Cotton Pygmy Goose, Comb Duck etc. are spotted here during this season. The lake area is owned by South Eastern Railway, though the Forest Department of West Bengal also looks after the place. Efforts are made by local residents, Forest Department and Railways to improve the environment for the birds. Forest Ministry of the State Government of West Bengal intends to convert the lake to a 'wildlife conservation centre'.(22.5820669,88.283338)edit
