Bandhavgarh National Park is a very popular park for its large biodiversity and Bengal tiger population. A lot of trails are closed to tourists, so in order to see the Bengal tiger, be sure to book a safari trip in advance - you can check here available guided tours.
The park is divided in four main zones, but Tala is the most sought-after zone because of its higher tiger density. If you're not a fan of safari trips, you can enjoy long walks in the forest where you can see the large-billed crow, yellow-crowned woodpecker, sapphire flycatcher and great cormorant.
Try to plan your trip outside the monsoons season, meaning from December until May. The nearest airport to the Bandhavgarh National park is a 4 hour drive away in Jabalpur, which is well-connected to Delhi with daily flights.
