|Notable features||Morph Ball tunnel containing pillars with destructible segments|
|Significance||Access to Chapel of the Elders|
Chapel Tunnel is a room in Phendrana Drifts in Metroid Prime. It is a passage for the Morph Ball, with two pillars obstructing it. These can be passed by destroying lower sections of each with bombs; Samus can reach these by destroying boxes to fall down, each of which requires two bombs. After doing this, the far door can be reached.
