Topographical Features of La Gomera

Central Highland and Volcanic Peaks

La Gomera’s landscape is dominated by a central highland region, culminating in Garajonay at 28.0978°N, 17.2419°W, with an elevation of 1,487 meters. This central massif divides the island into distinct northern and southern regions. The northern slope is characterized by steep escarpments and deep barrancos, such as Barranco de Hermigua, indicative of intense erosional processes and volcanic activity. These barrancos radiate from the central highland, showing the interaction between volcanic formations and erosion. In contrast, the southern slope descends more gradually, presenting a varied terrain influenced by the central massif’s gradient.

Coastal Periphery and Ravine Networks

La Gomera’s coastal periphery is rugged, especially on the northern coast, which features steep cliffs. The southern coast is defined by a gentler relief with broader coastal plains. This topographical variation results from differential erosion rates and volcanic processes. The island’s intricate network of ravines is more prominent in the north, forming a complex drainage system. Valleys like Valle Gran Rey and Hermigua, with fertile soils, are shaped by the convergence of barrancos, reflecting La Gomera’s dynamic geological past. The topographical diversity from the volcanic central highland to the coastal edges makes La Gomera a unique geographical entity.
