Hōlei Sea Arch Sout Point Park Big Island, Hawaii, USA. At the end of Chain of Craters road, there is a short trail to the ocean and the Hōlei Sea Arch. At present, the sea arch is about 90 ft. (27.4 meters) high. The creation of this sea arch was within the last 100 years. This beautiful formation has a limited life span. The sea arch will eventually crumble and will no longer be a feature of the park. However, another will replace it as the cliff slowly migrates inland.
