I visited Bandhavgarh National Park in 2010. It is one the places where you have great chances for sighting a tiger. I took 6 jeep rides in 3 different routes and spotted tiger 4 times. Kanha,Ranthambore and Tadoba didn't spot any. April and May are the best months to spot animals as they come to a few waterholes left. Don't take the guaranteed elephant safari to spot tigers as they are stage set. Be sure not to wear bright colored clothes and carry a binocular.
