How about a tour of Kaziranga National Park on elephant back? If you find jeep safaris too run-of-the-mill while you’re out exploring the wilderness, try the elephant safari here. The national park is in north Assam by the river Brahmaputra and is home to the endangered Great One-Horned Rhinoceros.
If you want to cover more wildlife sanctuaries and national parks in North East India, you can also head to Pakke Tiger Reserve, Namdapha National Park and Dibang Wildlife Sanctuary in Arunachal Pradesh.
