This can apply to a specific quest, character, or just a game mechanic that irks you for some reason. For me, the most annoying part of any Zelda game would have to be the Silent Realms in SS. If you mess up even once you have to do the whole quest over again, having to reobtain all the orbs that gave you trouble the first time. Not to mention that the guardians coming after you can prove creepy and stressful (especially if you aren't near another orb). Those sections game me a ton of trouble and would have made me quit the game if I wasn't already so far into it.
Another section that, while not as creepy, proved difficult to complete is fighting Head Thwomp, the second boss in OoA. You have to drop a bomb into his head when it rotates to a specific side, which is tricky since you can't exactly time when the platforms come. I spent hours and hours replaying this section, and was only able to beat it with the help of save and restore points.
