Hawaii may be known for its natural beauty but there also lurks a hidden danger within the scenic state. On average, one tourist a week dies in Hawaii, most of them from drowning. That's 13 times the national average - and the number of drownings is on the rise. Sandy Beach is one of Oahu's most popular tourist spots, but signs warn of the dangerous shore break. Another reads "no swimming." But that usually doesn't stop tourists from jumping into the water.
