India
Less well known than Bandhavgarh National Park, Corbett National Park and Tiger Reserve is a beautiful, remote park in the foothills of the Himalayas, a great place to experience real wilderness.
There are about 100 tigers in the park - so you have a good chance of spotting one - plus Asiatic elephants, crocodiles, otters, jackal, sloth bears and leopards.
World Big Cat Safaris is a fully-bonded UK-based tour operator run by former safari guides. They arrange tiger safaris across India.
