 Mount Aloia presents a rough topography with an altitude ranging between 80 and 629 metres from the Alto de San Xiao, from which spreads an extensive stretch of the River Louro and the Miño until its mouth.The soils are acidic, of low to average depth, presenting granitic substrate that often emerges, resulting in rocks and stones, a characteristic element of the landscape of the region of the lower Minho ("O Baixo Miño").It is a Site of Community Importance.
