There are two sets of mountain ranges located between the municipalities of Alicia and Ubay on the northeastern side of the mainland which generally trend to the north and south directions. The first range attains a maximum elevation of 404 meters above sea level while the second range of elongated clusters of hills has a maximum elevation of about 120 meters above sea level. The northern end of the mountain range is drained by the Lomangog River while the southern end by the east-flowing San Pascual River which empties into Cogtong Bay.
About two kilometers south-southwest from Tubigon is Mt. Ilihan which is 240 meters high with steep, almost bufflike sides. Farther east are two mountain ranges, Mt. Tan-awan and Mt. Candungao with 460 and 500 meters elevation, respectively. Both are prominent landmarks rising as they do several meters above the surrounding countryside. From Mt. Tan-awan going southwestward, the range presents a monotonous karst topography, declining gradually in height until finally it joins the foothills about 4.5 kilometers southwest of Calape. The main range of hills extending from Calape southwestward joins the southwestward trending mountain range from the interior, runs south and out to Loon Peninsula and terminating in Punta Cruz (Maribojoc).
The Sierra Bullones Range follows roughly the trend of the south coast. It commences from the vicinity of Loboc, extends eastward and finally northeastward terminating at about Biabas, Candijay. The highest point of this range and in the entire province is Mt. Mayana (870 meters). Other prominent peaks found in this range are Mt. Gordo, Mt. Amicay and Mt. Binalao.
