Horizon Forbidden West has a huge World Map. This page reveals the full in-game map in high resolution.
The total map size of Horizon Forbidden West is ~24km² (2800m height x 8700m width). However, some parts are narrower and it’s not a perfectly square-shaped map. The actual explorable area is about 16km². Flying from the east end to the west end of the map takes about 12 minutes using the flying mount. There are areas of all types, from meadows to deserts, snowy mountains, jungles, beaches and oceans.

The map stretches far further from east to west than it does from north to south. Your journey starts in the east and will take you west during the story. There is also a small prologue area that’s not part of the main map. Additionally, many underground caves can be entered and explored as well.
