Sun Tower Access is a passage in the Chozo Ruins in Metroid Prime. A long, winding corridor connecting the Sun Tower to the Sunchamber, its walls are lined with arches supporting the ceiling. The floor has completely fallen away near the door to the Sunchamber, and the hole below is filled with water and Fish, while Tangle Weed grow around the edge. At the other end lies several stacked crates (some containing a gold Energy Capsule, as well as a lone Pulse Bombu after defeating the Flaahgra. This Bombu is absent upon subsequent visits, but a Chozo Ghost can be glimpsed when first reentering the room before it vanishes through a wall. Even after it disappears, its ethereal hissing can be heard throughout the room.

- 1 Pulse Bombu (only right after the Flaahgra battle)
- 1 Chozo Ghost (Appears once and flees.)
