During or after Faron Twilight, it is possible to escape the Faron Woods with an LJA. Full details can be found on the Forest Escape page.
It is possible to skip the mailman trigger that is on the way to Eldin Twilight. To do this, stand next to the white spot shown in the video, then throw the boomerang ahead and LJA when the boomerang is OoB. This works because the boomerang is over a void OoB.
There are various ways to reach Lanayru Province early by clipping through the gate that blocks access. A full list can be found here.
Instead of lining up Epona with the gate and bonking into it, it is possible to set her out of bounds by performing Map Glitch and come back later after finishing Eldin Twilight to jump on her back out of bounds and bypass the gate. This takes the same amount of time as 1 bonk for Gate Clip if set up very quickly.
In the Ordon Day 2 storyline when Link is in the Faron Woods, there is a gate blocking access to Hyrule Field South. It's possible to clip through this gate with Epona; methods can be found on the Forest Escape page under the Epona Methods section.
By running Epona into a seam in South Hyrule Field at a precise speed and angle, it is possible to clip out of bounds. This is a very tough trick as it requires a precise animation frame of Epona's dash. The below video shows a setup that is far more consistent, though a setupless clip (much harder) saves 25s.
Extended tutorial of the setup by Anorakkis that goes into more detail:

It is also possible to clip back through this gate with Epona coming from Hyrule Field South. This is currently useful in the fastest Wii any% route. [Video WIP]
The postman trigger is much smaller on Wii 1.0, so to avoid it, a jump attack will suffice. Perform a jump attack as human or wolf at two locations. See video for clear visuals.
More information about this trick can be found on the Text Displacement page.
It is possible to use a bomb boost to get out of bounds in the N. Faron warp portal area. Once up, you can use an LJA to get to a place where you can LJA to the Lost Woods entrance. This has been used in All Dungeons and 100% to get to Temple of Time quicker.
To do this, stand on the highest point of the root and line up the hearts on the HUD as shown in the video (1st heart in line with the other tree's right side). Now throw a bomb forward and instantly aim the boomerang as high as possible without looking right or left. Throw the boomerang and LJA instantly to get up on the slope. Mash B to continually jump attack to stay in place until the bomb explodes and pushes Link higher onto solid ground. Alternatively, wait a second before throwing the boomerang and LJAing so that the bomb won't take as long to explode once Link has reached the slope.
From here, roll around or backflip over the root of the tree and stand in the corner seen in the video. Then, aim roughly over a low point on the other side low point and LJA across. Roll forward 4 times and then roll left and slightly up; there is a slope here, so make sure Link gets up it in the first roll. (If unsure, enter first person to see where the limits of land and slope are.) Now use the map to aim at the Lost Woods entrance, throw the boomerang, and LJA as it is over the void on its way back to Link.
Using the same method as above, it is possible to LJA onto the wall and get out of bounds using only the boomerang. This is harder than the bomb boost method
Stand on the highest point of the root and align the hearts on the HUD the same as the bomb boost setup, then throw the boomerang as high as possible straight up. Mash B to stay on the ledge and keep mashing until Link stops slipping off of the slope. Holding left while mashing will prevent Link's sword from recoiling against the wall and knocking him down once he's up.
From here, follow the same path into Lost Woods as the bomb boost method above.
It is faster to stay human for the entirety of Grove 2 in All Dungeons. 100% transforms into wolf before entering Sacred Grove to collect the poe and back to human for Grove 2 Skip.
When entering Sacred Grove 2 as human:
The bomb chest shown contains 30 bombs and is only necessary for some categories.
Full details can be found at the Grove 2 Skip page.
This requires maximum height Moon Boots (1 frame window). The angle is not precise. After Moon Boots, jump attack once, then roll over the weird railing collision.
By getting Epona OoB in South Faron, it is possible to get to the shortcut load zone without Dominion Rod. Ride Epona around the Hyrule Field loading zone and use the OoB collision to get a little more height. Then ride Epona to the cliff by Coro's house and ride Epona off the cliff to get more height. Ride over to the shortcut and backflip into the loading zone.
Using a sidehop clip, wolf Link can clip through the gate, skipping the need to get the small key.
By getting Epona OoB in South Faron, it is possible to get Epona into areas not normally accessible. Ride Epona towards the mist area and use the minimap to position Epona in the spot where the mist area should be, then backflip off to void out. Run to the mist area, mount Epona, then ride her under the mist gate and backflip into the loading zone.
By getting Epona OoB in South Faron, it is possible to get Epona into areas not normally accessible. Ride Epona around the Hyrule Field loading zone and use the OoB collision to get a little more height. Then ride Epona to the cliff by Coro's house and ride Epona off the cliff to get more height (920-930 Y-pos). Ride over to where North Faron should be on the map and use the minimap to help position Epona near where the Forest Temple entrance should be. (Note: If Epona is positioned too close to the blue bokoblins, she'll get scared and clip in bounds.) Void out, then enter North Faron. Ride Epona OoB and behind the Forest Temple loading zone. Backflip in to enter.
There is a 100R chest in the Skull Kid 1 area that normally requires the spinner to access. However, it is possible to LJA over there, requiring only the boomerang. Stand on the very edge at the black spot on the ground at the top of the vines and then target above the arch. Line up the targets so they are slightly in the wall so that the LJA won't recoil.
Using a few precise LJAs, it is possible to skip the statue puzzle normally needed to open the path to the Master Sword. This is useful when using Fixed EMS.
Old 100% routes (with Fixed EMS) get the golden bug at Sacred Grove before Master Sword. There is a timesaver with clever targets to boomerang the bug through the wall without entering the walled off area. Once in the boomerang, the bug will come to Link during the master sword CS to be picked up afterwards.
