Siargao is a tear-drop shaped island in the Philippine Sea situated 800 kilometers southeast of Manila in the province of Surigao del Norte.
One of the well-known surfing waves on Siargao and the Philippines, with a reputation for thick, hollow tubes is “Cloud 9”. This right-breaking reef wave is the site of the annual Siargao Cup, a domestic and international surfing competition sponsored by the provincial government of Surigao del Norte.
The wave was discovered by traveling surfers in the late 1980s. It was named after a chocolate bar of same name and was featured by American photographer John S. Callahan in the United States-based Surfer magazine in March 1993. Cloud 9 also has a reputation for being a relatively cheap destination for surfers with many cheap accommodations and restaurants and bars to choose from. Source
