According to the PGLU and the Aringay Municipal Government, the town hosts several notable landmarks and industries, including the Centennial Tunnel, the Dulao milkfish industry, Bubon Pusi, and Samara Beach. These sites represent a mix of historical infrastructure, natural resources, and local economic activities within the municipality.

The Centennial Tunnel, located in Poblacion, Aringay, is a 500-meter structure built in 1913. Originally intended for a Philippine National Railways (PNR) line connecting to Baguio City, the project was abandoned during the Second World War. The tunnel, which measures 7.6 meters wide and 4.5 meters deep, was later used by the Japanese Imperial Army as a headquarters.

In the aquaculture sector, Dulao serves as a primary site for milkfish production. Over 400 fish pen operators utilize the area, which is part of a pilot project supported by the Bureau of Fisheries and Aquatic Resources (BFAR) and the Southeast Asian Fisheries Development Center (SEAFDEC). The quality of the local milkfish is attributed to the specific salinity and water quality of the lagoon fed by the Aringay River.

Additionally, the town features natural sites such as Bubon Pusi in Barangay San Eugenio, a dormant volcano used for camping, and Samara Beach, a coastal area in Barangay Samara equipped with resorts and picnic facilities.
