The scupper valve snorkel of the present invention is based on a conjoined tube within a tube located inside a lower section of a snorkel and designed to steer water droplets away from the snorkel diver's breathing path. The lower section of the snorkel has two valves. One is the scupper valve positioned at the lowest point of the inside tube. The scupper valve is designed as a light duty valve or a low resistance one-way watertight passage intended to allow droplets of water to drain into the main reservoir. This must occur without build up or trapping of water that could otherwise be drawn into the breathing path of the snorkel diver. The outer tube lower section contains a reservoir for holding residual water that travels down to the bottom of the snorkel and is contained therein. During the normal clearing operation, the reservoir can be emptied and water will exit out of the lower section and into the surrounding water.
