All Malignant Tunnel locations in Diablo 4 season 1

Malignant Tunnels are a new activity type in Diablo 4 season 1, Season of the Malignant. There are six of them scattered around The Dry Steppes, The Fractured Peaks, and Hawezar, and they function as mini dungeons that are packed with Malignant enemies, which you can kill to earn more Malignant Hearts.

In this Diablo 4 guide, we’ll show you where to find all six Malignant Tunnels, which we’ve also added to our interactive map.
