The Legend of Zelda: Breath of the Wild‘s first DLC package, The Master Trials, has added several new items. One of these items is the Travel Medallion.
The Travel Medallion can be found in a treasure chest near Tumlea Heights and North Akkala Foothill at the Lomei Labyrinth Island. This location is at the Northeast corner of the map.
To get to the island, you need to boost up using the wind power (hold B), obtained from killing Windblight Ganon in Vah Medoh, and then glide across the sea.
Once at the Lomei Labyrinth Island, find your way inside the Northern section.
The video below shows the path required to get to the treasure chest:
The Travel Medallion allows you to place a teleport nearly anywhere on the map, serving as a spot where you can quickly travel at any time similar to the towers. It’s a very powerful item, and one that any Season Pass owner should obtain as soon as possible.
