When you first begin your journey, you’ll notice that fast travelling is done with Travel Packs. These can be crafted, bought or found, but the point is that they are essentially finite resources, and you can easily run out if you’re bouncing around the map finding collectibles, for example. Luckily, there’s fairly simple way to get yourself infinite fast travel with the Golden Fast Travel Pack. This will unlock at Merchants after you reach Daytower, the Carja fort on the edge of Nora lands. After that all you need to do is go out and do some hunting for the resources - the job creation system can help you here - and soon enough you’ll be fast travelling without a care in the world. Except for all the deadly Machines of course.
