Just 60 miles away from Kolkata, where the River Ganges pours into the Bay of Bengal, the Sunderbans Wildlife Sanctuary is home to the world's largest population of Royal Bengal Tigers, perhaps the most beautiful and dangerous animal on the planet.
The journey from Kolkata ends up taking around 6 hours because of the poor quality of transport that runs between the city and the sea, so normally, you need to visit the sanctuary for a couple of nights to make it worthwhile, although simply to escape from the hustle and bustle of the city for a short time makes a welcome break.
Many travel agents offer a tour package to the park, which includes transport, accommodation and permits, as well as a guide, and this is the best way of seeing the wildlife.
