Fast travel from a gang hideout
Fast travel from a gang hideout is free – you don’t have to pay anything for “teleporting”. This option isn’t available right from the beginning. You need to purchase it from the book available in the camp. This adds a map right next to Morgan’s bed – use it to select your destination. This method of fast travelling has the most options because it allows you to travel to almost any location. Arthur travels on a horse which means that you will always have your mount with you.
WARNING, SPOILERS AHEAD!
After completing the storyline, John Marston can also use the map to fast travel. It is located in one of the rooms in Beecher’s Hope.
