Valugan Boulder Beach

Valugan Boulder Beach is a distinctive coastal attraction on the eastern shore of Batan Island in Basco, Batanes, Philippines. Stretching along the Pacific Ocean at the foot of Mount Iraya, the beach is covered with smooth, rounded andesite boulders deposited by the volcano's eruption centuries ago. Known for its dramatic landscape, powerful waves and unobstructed views of the sea and mountain, it is valued for sightseeing and photography rather than swimming.

Visitors can expect a long shoreline completely covered with smooth, rounded boulders of varying sizes instead of sand, facing the open Pacific Ocean with Mount Iraya as a backdrop. The area is open and exposed with strong waves crashing against the rocks, no shade or commercial development, and wide views ideal for photography and sightseeing. The terrain is uneven and rocky, suitable for walking along the edge and viewing the coastline but not for swimming.

The boulders were deposited along the eastern coast by the eruption of Mount Iraya, the active volcano dominating northern Batan Island. Geological records associate the volcano's activity with eruptions around 325 BCE and most recently in 1454, which scattered andesite rocks along the shoreline and shaped the present boulder beach landscape.

Valugan Boulder Beach is an iconic natural landmark of Batanes and a symbol of the volcanic origin of Batan Island. It forms part of the distinctive Ivatan cultural landscape and is a key feature of local tourism identity, often visited as part of northern Batan island tours.
