On the left-hand border of the Arucas ravine, between Hoya de San Juan and Montaña de Cardones, we find two inhabited villages known by the names of El Hornillo Alto and El Hornillo Bajo. It was originally a small village consisting of the houses of farm labourers, in the middle of the farms where they worked. El Hornillo (literally, “little oven”) owes its name to the fires that were always lit in country houses, most of which had their own ovens for making bread or cooking.

However, for other authors, the name of Hornillo could refer to the fact that local temperatures are always relatively high because of the layout of the land, with heat tending to accumulate.
