The name aragan in the local dialect refers to a kind of seaweed which is found in the coral stones along the seashore. But Barangay Aragan is located on the eastern part of Cabugao which is very far from the sea. Most of the houses are located on the hills on the southern part of the valley.
Why the barrio is called Aragan? Its just a simple story. Once the valley was covered with a kind of seaweed called ar-aragan. This weed was so thick that it almost covered the surface of the vicinity. From that time on, the locality was called Aragan.
Barangay Aragan is situated near the mountain side called Ilocos Range. From the town proper it is approximatelty five kilometers away from the rear end and another two kilometers long at the back end. It has a population of 685 and has an Elementary School.During the old days, theonly means of transportation was the pasagad, a cart pulled by a carabao. Nowadays, cars and motorcycles can reach the place already.
