Gain momentum in the room to the left, then jump at the edge of the runway in order to land on the first pillar. Requires a runway of at least 2 tiles (with no open end) in the adjacent room. Shrinking Samus' hitbox before landing makes the jump a little easier.

Entrance condition:

"comeInRunning": {
  "speedBooster": "any",
  "minTiles": 1.4375
}

Requires:

"HiJump",
"canCrossRoomJumpIntoWater",
"canTrickyJump",
"canPlayInSand"

Dev note: This is not technically a canCrossRoomJumpIntoWater, but it is used here because of the way the momentum changes as Samus enters the water.
