In the late game in Valencia, Bale gave Real Madrid the lead after five minutes. Karim Benzema ran in on goal but when the ball was held up by water on the pitch cut it back to Bale who side-footed the ball home.
It was the Welshman's first goal in La Liga since his second goal, an 86th minute equaliser, in a 2-2 draw against Villarreal at the start of September in 2019, a match which he ended by collecting a red card.
Real dominated the first half but could not find a second.
Instead, Levante levelled 28 seconds into the second half.
The ball broke to unmarked Roger who beat Thibaut Courtois with a hard low shot
Levante took the lead in the 57th minute when Jose Campana met a deep cross with a sweet volley into the top corner.
Real manager Carlo Ancelotti promptly yanked off Bale, Isco and Eden Hazard in a triple substitution.
One of the subs, Vinicius repaid his coach in the 73rd minute, accelerating onto a pass from Casimeiro, shrugging off a defender and rolling a shot into the corner of the net.
Seven minutes later, David Alaba nodded a Levante free kick down into his own six yard box and Rober Pier gleefully thumped the ball home from close range.
With five minutes left, Vinicius again equalised.
Receiving the ball wide of the post and near the goal-line, he still somehow found the net, lofting the ball round goalkeeper Aitor Fernandez and in off the far post.
Two minutes later, Fernandez was sent off for handling outside hs area to stop a Real counter-attack. Because Levante had used all their substitutes, defender Ruben Vezo went in goal but Real could not find a winner.
