Pause and just before the pause fully triggers, jump and press left, and then disable Gravity and Spring Ball. With HiJump and a good jump, it is possible to jump straight to the high ledge, but quickly pausing and turning on Spring Ball and jumping again can help as a backup. Without HiJump, use this jump to start an IBJ directly over the spike pit, then boost horizontally to the left ledge. Jump over the Cacatac and the spike pits with suitless Spring Flings. The final jump can be done the same way as the first, if Samus is not able to wall jump.
