Dos Hermanos Island is located in Pagudpud, Ilocos Norte, Philippines.

 

Also in the heart of Barangay Balaoi are two identical mountains called the Dos Hermanos Island. Old folks say that in olden times, there were two brothers who were close to each other they vowed to remain together until death. One day, they went fishing and were still at sea when they were caught by a typhoon and drowned. Because of their loyalty to each other, and to serve as an inspiration to others, they were transformed into the two mountains prominently seen in the place.
