Guinobatan is like a maiden lying upon a verdant mantle. It is a valley cradled by mountains and rolling hills dominated by the grandeurs of two magnificent volcanoes-the near perfect Mt. Mayon, which is one of the most active volcanoes in the Philippines towering at 8,000 feet above the sea level, in the east side and Mt. Masaraga, a legendary dormant volcano in the northeast. Its land area stretches southwards of the Albay province at 123º31′ and 123º15′ east longitude and between 13º10′ and 13º15′ north latitude. It stretches from southwest of the municipality of Camalig, and is bounded by the municipalities of Pio Duran and Jovellar in the south and by Ligao in the northwest. It is 520 feet above the sea level and is recipient of a cool and tropical temperature. The third largest municipality in Albay, it occupies 203 sq. kilometers or 20,300 hectares or 7.95% of the total land area of the province. Its land area is defined by mountainous terrain, rolling hills, and plains. 49.26% of its total land area or 10,000 hectares are located on undulating, rolling to moderately steep and very steep slopes.
Guinobatan is blessed with natural bounties. The best sand for infrastructure, limestone for cement making, perlite, agricultural crops, ornamental plants, inland springs, and tasty foods like longaniza de Guinobatan, pilinut delicacies and baraquillos to name a few are all found in it. It also has horticultural areas that make it known to be “The Garden Town“.
