Photo Gallery

Mount Isarog volcano in the background rises to 1966 m NW beyond the lower flanks of Iriga volcano, which form the sloping terrain in the foreground. Mount Isarog is an isolated stratovolcano occupying the broad isthmus between Lagonoy Gulf and San Miguel Bay. The summit of the volcano is cut by a large crater, which has a prominent, deep and narrow breach on the lower eastern flank.
