Which U2 song contains the repeated lyric “I have climbed the highest mountains”?

“I Still Haven’t Found What I’m Looking For” contains the lyric “I have climbed the highest mountains.”

The song appears on U2’s 1987 album The Joshua Tree and was released as the album’s second single. Its lyrics use images of searching, belief, love, and spiritual uncertainty, giving the song a gospel-influenced character despite its rock setting.

The recording features Bono’s lead vocal, The Edge’s guitar work, Adam Clayton’s bass, and Larry Mullen Jr.’s drums. It became one of U2’s most successful songs, reaching number one in the United States and Canada and becoming a major international hit.

The line is sometimes associated with “Where the Streets Have No Name” because both songs appear on The Joshua Tree. They are separate tracks: the mountain lyric belongs to “I Still Haven’t Found What I’m Looking For.”
