Impala have a tough life with so many predators looking for a meal. We visited near the end of the dry season when many watering holes were drying up and animals were in close proximity. The impala would approach the water and then the slightest breeze or noise would scare it away. Lions or leopards could be in the brush nearby (we saw 3 lions here a day or two later) or crocs could be in the water patiently waiting to ambush. Once the impala finally did make it down to the water the steep bank was a challenge, if you look closely at the edge you can see the marks from where their hooves would slide down as they tried to reach the water.
