A 4th class municipality, it comprises twenty‐two barangays, of which only two are considered urban (Brgy. Ubos and Takas), and twenty are rural. Majority of these rural Barangays are in the upland where accessibility is very poor. Only those barangays in the Poblacion and its vicinity have good access roads which can be reached by all types of vehicles. The town center is approximately 150 kilometers from Iloilo City and about 50 kilometers from San Jose, the capital town of the Province of Antique. Busog and Culyat are the farthest Barangay from the town proper and can only be reached by foot. The municipality has a total land area of 27,379 hectares based on the cadastral map submitted and approved by the DENR. However, it was not accepted by the LGU and subjected to petition or resolution in 1995 from Sangguniang Bayan strongly repudiating the result of said cadastral survey (Cad. 942‐D) in view of Valderrama’s larger territorial claim composed of a total 34,000 hectares, which also covers part of the mountainous portion of the Municipality of Calinog, Iloilo. To date, however, this petition has not been acted upon by the agency concerned. As one of the municipalities in the heart of the Panay Mountain Range, Valderrama is ruggedly mountainous. More than half (53%) of its land area has steep slopes of 50% and above. Its highest peak in Mount Baloy has an elevation of more than 2000 meters above sea level. The largest part of its land area has an elevation ranging from 300 to 800 meters above sea level. It has generally loose soil composed of Alimodian Series, the Umingan, and undifferentiated (Source: Soil Map, Provincial Agriculture, Antique) which made it prone to erosion and landslide. Alimodian Series and Umingan are the soil types which can be found in the downstream portion of the municipality, while the undifferentiated ones can be found in the upper or mountainous area.

The Mines and Geosciences Bureau (MGB), in their geologic studies, places almost 75% of the entire area of Valderamma, especially those with steep slopes, highly susceptible to landslide, and the lowest part along the mainstream of Cangaranan River as highly susceptible to flooding. Based on Corona’s classification, the municipality has Type 1 climate with two pronounced seasons, dry from December to May and wet from June to November. This type has a maximum rain period from June to September. Areas characterized by this climate type are generally exposed to the southeast monsoon and get a fair share of the rainfall brought about by the tropical cyclones occurring especially during the maximum rain period which is usually August.
