There are many rhino that can be seen in Bardia, although they are easier to see in the dry season when the grass dies back a little. One way to see them is on the back of an elephant.
The Blind Rhino
In the park headquarters the rangers look after a blind rhino with an interesting history. He was found when his mother was killed by poachers and despite being re-released into the park kept getting attacked by other wild rhino. Eventually he accidentally killed someone in the village and since then has been kept at park headquarters where you can go and see him from very close-up.
