The following guide will explain more about how you can fast-travel using signposts in The Witcher 3: Wild Hunt.
The Witcher 3: Wild Hunt features a massive open world that runs for around 88 square miles. It is going to take you at least half an hour to ride from one end to the other, and that is provided there are no obstacles or enemies in the way.
This is where fast traveling comes into play. There are numerous signposts scattered across different parts of the map. These signposts help you fast-travel to another location in The Witcher 3 and save crucial time that can then be spent on completing quests or finding gear such as the Wolven armor set. How to unlock fast travel in The Witcher 3
You will unlock the fast-travel feature early on in the game. You will discover your first signpost as soon as you reach White Orchard with Vesemir, which is the first playable area in the game, following the tutorial section.
There are 228 signposts (which serve as fast travel points) to find and use in the game. Once you discover a new signpost during your travels in The Witcher 3, the fast-travel location will be marked on your map with a green signpost icon. These will help you to find the closest fast-travel location in case of emergency, albeit you cannot fast-travel if you are in combat.
Interacting with a signpost will open up the map. You then need to select another signpost to fast-travel to. When done, you will start from the selected signpost location.
