Hollow Knight Silksong Wisp Thicket Guide & Location
The Wisp Thicket in Hollow Knight: Silksong is a hidden side area connected to Greymoor. Small but important, it holds a Flea, lore ties to the Father of the Flame boss, and a shortcut into the Underworks. If you’re wondering how to reach it, what’s inside, and why it matters, this guide has you covered.
How to Access the Wisp Thicket
To enter the Wisp Thicket, head to the tower next to Halfway Home in Greymoor. Take the northern exit and use the balloons to bounce toward the north-west. At the very top, you’ll find a room with a ceiling passage that looks unmarked. Break through this hidden spot to uncover the entrance.
Inside, the path winds left and eventually links up to the Underworks, making it a useful connection point if you’re exploring that region.
Inhabitants of the Wisp Thicket
The Wisp Thicket is quiet compared to other parts of Pharloom, but it does contain:
A Flea – needed for The Lost Fleas questline.
Minor enemies – a few weak spawns that resemble glowing wisps, meant more for flavor than challenge.
Because the area is so small, it functions more as a secret passage and quest location than a combat arena.
