The Chadpidan Boulder Beach is another popular tourist spot in Batanes. It is known for its numerous, massive, round boulders stretching along the shore of the whole beach.
Historically, the boulders are spewed from Mt. Iraya, a now inactive volcano.
Strong waves from the China Sea helped to smoothen the boulders over time.
Not only to tourists, the place also serves as a leisure place for the Ivatan, the people of Batanes.
