The trail is named after the Grysbok, an endemic fynbos ungulate commonly seen along the trail. Other frequent large mammal sightings include springbokplains zebra, red hartebeest and blue duiker. Many smaller mammals such as the honey badger (Mellivora capensis), scrub hare and three mongoose species also occur in the reserve. A total of 25 mammal species have been recorded on the reserve. 

Listed below are some of the mammals that can be found along the trail:
