Mount Guiting-Guiting is the highest mountain in the province of Romblon located at the heart of Sibuyan Island and dominates the entire island. Guiting-Guiting, in the local Romblomanon dialect, means "jagged". The mountain is one of the focal points of Sibuyan's declaration as a biodiversity haven. The entire island has been compared numerous times with the biodiversity endemism rate of the Galapagos islands. This endemism prompted much of the mountain and its slopes to be protected under the Mt. Guiting-Guiting Natural Park, established in 1996.
