A snorkel is provided. The snorkel has a mouthpiece portion and a waterproof structure which is disposed at an end opposite to the mouthpiece portion. The waterproof structure has a tube body and a lid body. At least one vent and a first stopper are disposed at the tube end portion of the tube body. The lid body has an opening and a second stopper. The tube end portion is provided within the lid body by passing through the opening. When the waterproof structure is located above the water, the waterproof structure is in fluid communication with the mouthpiece portion by the opening and the vent. When the waterproof structure is located below the water, the lid body is floated upwards so that the second stopper contacts with the first stopper portion to substantially block flow of the water from the opening into the vent of the tube body.
