In Monster Hunter Wilds, the Seikret mount makes life easy for you to traverse the map but Fast Travel is even easier!
Although Fast Travel is available from very early on, you don't actually get the tooltip that explains how to do it until several quest missions in.
All you have to do is Press Start then go to your Detailed Map. Then, hover locations like Base Camp or Pop-Up camps - you'll see the option pop-up then simply press X to travel there.
We recommend Fast Traveling only when you're truly short on time though, because there are a lot of benefits to taking your time to explore, collect materials, and understand the lay of the land.
