The origins of the Marcos y Cordero Route date back to prehistoric times, when volcanic eruptions formed the terrain of La Palma. The early inhabitants of the island, the Benahoarites, used similar natural paths to move between their settlements and access essential water resources. These rudimentary roads were vital for survival, providing access to water sources in the mountains and connecting the island’s various communities.

With the arrival of the Castilian conquerors in the 15th century, the Marcos y Cordero Route began to acquire a new importance. Colonists quickly recognized the value of La Palma’s natural resources and used the route to transport water and agricultural products, especially sugar cane, from the highlands to markets and ports. During this period, the first irrigation ditches and tunnels were built, which today form an integral part of the route. These engineering works not only facilitated the transport of water, but also demonstrated the settlers’ ability to adapt the landscape to their agricultural and economic needs.

During the 17th and 18th centuries, the importance of the route as a main artery for water management grew significantly. Aqueduct and tunnel systems were expanded and perfected to handle the growing water requirements for crop irrigation. The engineering skill of the time is reflected in the meticulous construction of these structures, which not only stood out for their functionality, but also for their integration with the natural environment. These systems remain a vital part of the route, and their continued maintenance protects both biodiversity and the region’s ecosystem.
