Barangay Lisondra. Surigao City. This rock islet is best defined by the ranges of its unique, natural rock formations, solidly and concretely enhanced by the different variations of its colors and shades. Opposite is another isolated vase-like rock formation complementing this somewhat mysterious creation of nature, which was a burial ground of the early inhabitants of the surrounding islands. It only takes a 40-minute boat ride to reach this unique rock formation coming from the city proper.
