In footage uploaded to Imgur, the man can be seen posing with his girlfriend on the waterfall.
Then he gets down on one knee - much to her obvious surprise.
The girl covers her mouth in shock as he starts proposing to her.
But before she has the chance to respond, disaster strikes.
He reaches out with the rung, but drops it in the gushing waterfall before he can put it on his girlfriend’s finger.
He looks for it in the water, but soon gives up to continue with his proposal.
His girlfriend says yes, and gets down in the water to giver her new fiancé a kiss.
