At the foot of the cliff of the North Cordillera Mountain Range is the 12-km winding bridge known as the Patapat Bridge, popularly known as the French Riviera of the North. At the upper part of the cliff, one can still see the etched foot bridge that was the only link between Ilocos and Cagayan Valley in the 1960's. While at the middle of the Patapat Bridge, one can take a look at the awe-inspiring panoramic view of the verdant mountains and the sea below. A glimpse of the old footbridge adds grandeur to the breathtaking view.
While at the scenic Patapat Viaduct, one can get an enchanting view of Pasaleng Bay, its beauty unmarred by a shipwreck dating from the Japanese occupation. It is believed that the other half of the ship lies eight fathoms at the depths of scenic Pasaleng Bay, while the other half is at 20 fathoms at scenic Agua Grande. Here, treasure hunters and other adventure seekers, or even simple divers are treated to a wonderful diving experience.
