Houyhnhnm Land is the island home of the Houyhnhnms, a race of sentient equines who govern their society with strict order and reason. It is also the home of the savage Yahoos, a race of primitive humanoids that act like animals but are governed by emotion and instinct. The island has vast plains and grassy fields that suit the equine residents quite well. It also has forests and jungles which most Yahoos make their homes in.From a map of Houyhnhnm Land and its surrounding regions, it may suggest that Houyhnhnm Land is south of modern-day Australia.
- Horses were first introduced to nearby Australia in 1788 by British settlers.
