Kaziranga's tall elephant grass and Brahmaputra floodplain hold two-thirds of the world's greater one-horned rhinos, a conservation story you can watch unfold from an open jeep at dawn.
Assam's grasslands look almost prehistoric at first light, mist lifting off the swamp as a rhino's armoured grey bulk emerges from the reeds to graze. The species was hunted to a few hundred animals last century; today Kaziranga alone holds over two thousand, grazing alongside wild water buffalo, swamp deer and, if you are lucky, a tiger crossing the track ahead of the jeep.
The park is split into ranges — Central, Western, Eastern and Burapahar — and each has a different character, from open floodplain to denser forest edge, so a two-day visit covering more than one range is worth the extra permit. Early starts matter enormously here: the grass is at its shortest and the animals most active in the hour after the gates open.
Kaziranga closes entirely during the monsoon floods, so plan a visit between November and April when the park is dry and accessible. Add an elephant-back safari for a different vantage into grass too tall to see over from a jeep, though book it the evening before — slots fill fast in peak season.
