(This is a tough one. Opposite where the character is standing, is normally an explodable wall. Since I destroyed it once, it doesn't come back. The only way to get there is to time and throw a bomb so that the explosion takes out the wall. The easiest way to do this that I found is to run up to the edge with a bomb, jump into the air, throw the bomb, turn around and use the now-available second jump to get back onto the ledge. Failing that, once you take out the wall, simply come back around and jump across - it won't come back.)
