The technique usually called the Zora River Boulder Skip is the best match for the “water-powered boulder glitch” in Ocarina of Time. To perform it, megaflip from the boulder into the river, correct Link’s angle as he enters the water, use a light down-right input to start an ESS when he lands, and repeatedly release and hold Z to steer a HESS onto the bank. Turn that HESS through the gap between the rocks, then press B as Link begins pushing through to sheath the sword and stop the movement.
This is a difficult, non-TAS sequence break. It bypasses the boulders blocking the rest of Zora’s River and is used in documented any% speedrun routing to obtain Magic Beans early. Expect repeated attempts: the most common miss sends Link back into the water instead of carrying him onto land.

What the Zora River Boulder Skip does
The boulder skip is a movement exploit at the rock obstruction in Zora’s River. Instead of following the ordinary route around the river, Link is launched from the boulder with a megaflip, enters the water at a controlled angle, and converts that momentum into an ESS and then a HESS. The resulting movement lets him reach the bank and push through the narrow opening between two rocks.

The location, the boulders, the water entry and the HESS movement identify it as the Zora River Boulder Skip. It is not a menu trick or an item duplication method; the entire sequence depends on positioning, timing and angle control during movement.

When it works, Link is past the boulders that block the remaining river area. In speedrun routing, that shortcut is valuable because it permits an early Magic Beans pickup in an any% run. The skip itself does not grant Magic Beans automatically; it opens the route that makes the early collection possible.
What you need before attempting it
- Reach the boulders blocking the remainder of Zora’s River.
- Have bombs available for the megaflip setup.
- Be able to use the shield during the bomb setup and perform a backflip or sidehop immediately after the explosion.
- Use a controller or input method that lets you make small joystick adjustments and release and hold Z quickly.
- Allow time for practice. The sequence is precision-heavy, and a failed attempt generally returns Link to the water rather than placing him on the bank.
No special item, hardware accessory or product is required beyond the normal game, a usable controller and bombs. The critical preparation is being at the correct boulder and having enough room to set up the explosion without changing the intended launch position.
Movement terms used in the setup
Megaflip
A megaflip combines a bomb, the shield and a timed acrobatic movement. Place a bomb, raise the shield, and when the bomb explodes, quickly roll into a backflip or sidehop. The blast supplies unusually large forward movement compared with a normal flip. For this skip, the megaflip starts from the boulder and sends Link toward the river.
The important part is not merely getting a large launch. Link must enter the water at an angle that can be corrected into the later ESS. A megaflip that reaches the river too far left, too far right or at the wrong orientation can be technically successful while still making the boulder skip impossible.
ESS
ESS is the controlled movement state used immediately after Link lands. In this sequence, the landing input is a light movement down and right on the joystick. The input is deliberately light: an aggressive hold can turn Link too sharply or prevent the desired state from starting.
HESS
HESS is the faster movement state used to carry Link from the water toward land and then through the rocks. The technique changes Link’s angle by releasing and holding Z repeatedly. The goal is to steer the HESS onto the bank without losing the movement state. Once Link is on land, the HESS must be turned through the gap between the two rocks shown in the demonstration.
Exact trigger procedure
-
Stand at the river boulders
Go to the boulders that block the rest of Zora’s River. Identify the launch boulder and the nearby water area before placing a bomb. Your reference point is the obstruction itself, not a general location elsewhere in the river; the launch, water entry and landing all depend on this specific geometry.

Set up the megaflip
Place a bomb beside the boulder, raise the shield, and wait for the explosion. As the bomb detonates, quickly roll into a backflip or sidehop. The timing window is short. A normal roll, a late flip or a flip started without the shield will not provide the same launch.
-
Correct the angle at water entry
The instant Link hits the water, hold the joystick to the right slightly harder than you would for an ESS. This stronger rightward input establishes the angle needed for the next movement state. Do not apply the landing input early; the water-entry correction and the landing correction are separate moments.
-
Start the ESS on landing
The moment Link lands, move the joystick lightly down and right. The input should be gentler than the rightward correction used at water entry. This places Link into the ESS that carries the sequence forward.

Use Z to steer the HESS toward land
Repeatedly release and hold Z while Link is moving. Each change is used to adjust Link’s angle. Continue until the HESS reaches land. The demonstration warns that many attempts instead produce a HESS back into the water, so reaching the bank is the first major checkpoint.

Turn through the rock gap
After Link is on land, turn the HESS so he passes between the two rocks shown in the demonstration. The gap is the route through the obstruction. A landing that reaches the bank but approaches the rocks from the wrong angle can still fail here.
-
Stop the HESS inside the gap
When Link begins pushing through the gap, press B to sheath the sword. Sheathing stops the HESS at the point where the movement has carried him through the rocks. Pressing B too early can end the movement before Link clears the obstruction; pressing it too late can send him past the useful line or back into a bad position.
Why the timing is split into separate inputs
The sequence has three different control problems: launching from the boulder, setting an angle in the water, and converting the landing into a steerable HESS. Treating them as one long joystick hold is unreliable because each phase needs a different strength and timing.
The megaflip supplies the initial displacement. The slightly stronger right input at water contact points Link toward the intended line. The light down-right input at landing starts the ESS without over-rotating it. Z releases and holds then provide incremental angle changes while the HESS is active. Finally, B ends the movement only after Link starts pushing through the rock gap.

Different attempts can have small positional differences, so watch for the water contact and the landing rather than relying on an inflexible rhythm.
Troubleshooting common failures
Link does not launch far enough
Recheck the bomb-and-shield setup. The megaflip requires the bomb to be placed at the boulder, the shield to be active and the backflip or sidehop to begin quickly when the bomb explodes. If any of those actions is late, Link may perform an ordinary movement that cannot reach the required water entry.
Link enters the water but the angle is wrong
Apply the rightward water-entry correction at the instant Link hits the water, and make it slightly stronger than an ESS input. A correction that is too weak leaves Link on the wrong line; a correction made before water contact can be overwritten by the landing sequence.
The ESS never starts after landing
Use the light down-right input at the moment Link lands. Holding the stick too hard can produce a different turn, while moving too late can lose the movement state. Practice identifying the landing visually and make the down-right motion a distinct second input after the water-entry correction.
The HESS sends Link back into the water
This is the documented common failure. The release-and-hold-Z adjustments are angle corrections, not a single permanent direction. Make smaller, more deliberate changes and watch whether Link’s path is converging on the bank. If the line is clearly returning toward the water, reset and attempt the megaflip again rather than trying to salvage the position.
Link reaches land but cannot pass the rocks
Landing on the bank is only an intermediate checkpoint. Once on land, turn the HESS toward the opening between the two rocks. If Link approaches the gap from the wrong side or at too shallow an angle, the movement may stop against the rock. The next attempt should prioritize the line through the gap, not merely reaching any part of the bank.
Link passes the gap but the movement continues
Press B when Link begins pushing through the gap to sheath the sword and stop the HESS. If B is pressed before the push starts, the movement can end short of the obstruction. If the input is delayed, Link may lose the useful position after clearing the rocks.

| Approach | Setup | Execution | Reliability | Result |
|---|---|---|---|---|
| Zora River Boulder Skip | Megaflip from the boulder into the water, with bombs and shield | Water-entry angle correction, light down-right ESS input, repeated Z releases and holds, then a HESS turn through the rock gap | Low for beginners; repeated attempts are normal because many failures return Link to the water | Bypasses the boulders and supports early Magic Beans routing in documented any% play |
| Ordinary route progression | No megaflip or precision water setup | Uses the normal route rather than the boulder sequence | Not stated for this comparison in the demonstration | Does not use the skip; it leaves the sequence-break advantage unused |
The table separates what is established about the exploit from what is not. The skip’s speedrun value is documented, while a quantified success rate or a timed comparison with ordinary progression is not established. It is therefore better judged by whether you need the early route and are willing to practice the execution than by an invented percentage or time claim.

Learn the launch first
Begin by practicing the bomb, shield and backflip or sidehop at the boulder. Do not add the water steering until the megaflip consistently sends Link into the intended part of the river. This isolates the setup error from the angle-control error.
Add the two angle moments
Once the launch is repeatable, focus on the distinction between water entry and landing. Use the slightly stronger right input at contact with the water, then the lighter down-right input at landing. Keeping those moments separate prevents the second input from being applied too early.
Practice Z changes as corrections
When the ESS is stable, add the repeated release-and-hold-Z movement. Make each change in response to Link’s direction rather than repeating a fixed pattern. The objective is to bring the HESS onto land, not to perform a predetermined number of Z cycles.
Finish with the rock gap
After reaching land, practice the turn through the two-rock opening and the B input independently in your mental sequence. The complete attempt has two endpoints: first the bank, then the push through the gap. Treating them as separate checkpoints makes it easier to identify where a failed attempt went wrong.

Version and release caution
The available demonstration is labeled non-TAS, and the general glitch reference discusses Ocarina of Time techniques without providing a release-by-release test for this particular skip. The exact input sequence should therefore not be presented as verified on every version or platform.
If you are using a different release from the one shown in the demonstration, treat compatibility as unconfirmed until you test it. Differences in timing, collision behavior or input handling could change the result. The documented procedure establishes how the demonstrated sequence is performed; it does not establish universal cross-version behavior.
Quick attempt checklist
- At the correct boulders in Zora’s River.
- Bomb placed and shield raised.
- Backflip or sidehop started quickly at the explosion.
- Right input held slightly harder than an ESS at water contact.
- Light down-right input applied at landing to start the ESS.
- Z repeatedly released and held to steer the HESS toward land.
- HESS turned between the two rocks after reaching the bank.
- B pressed as Link begins pushing through the gap.
Success means Link is beyond the boulder obstruction, not merely in the water or on the bank. From that position, the sequence-break route can be used for the documented early Magic Beans objective in an any% run.
