Climbing Mount Fay in Hollow Knight: Silksong is one of the game's most elaborate platforming sections. In fact, it's essentially an entire region devoted to a single challenging goal—climbing your way to the top of the mountain. You'll have to use every movement ability open to you, including the Clawline, which you'll have to unlock if you haven't already, in order to make this trip.
The reward is worth it, though, since Mount Fay gives you the Faydown Cloak double jump ability, allowing you to reach lots of new places. It's also a vital upgrade for doing certain quests like the Great Taste of Pharloom. Either way, here's how to get to Mount Fay in Silksong and climb it via the route, along with videos showing both.
