The waterfall acts as a natural municipal border, with the left bank belonging to Arzúa and the right bank to Touro.
The drop is formed by a notable geological fault that interrupts the course of the Saímes River.
The surrounding forest is a prime example of an Atlantic riparian gallery forest, which is protected under local ecological guidelines.
The waterfall is locally known as 'Fervenza de Santa Marta' due to its proximity to a nearby parish.
Fervenza das Hortas is a 30-meter-tall waterfall located on the boundary between the municipalities of Arzúa and Touro in Galicia. The waterfall is fed by the Saímes River, which descends over a geological fault, creating a distinct drop that separates the granite rock of the riverbed. A small stone bridge spans the river near the waterfall, serving as a historical boundary marker between the two districts. The site is accessible via a trail that weaves through a dense, native riparian forest dominated by oak, chestnut, and laurel trees. During periods of heavy rainfall, the water volume significantly increases, intensifying the spray at the base of the pool. The surrounding vegetation is largely untouched, maintaining a high level of biodiversity characteristic of Galician riverside ecosystems. It is a key point of interest for hikers exploring the regional rural trails near the pilgrimage routes to Santiago de Compostela.
The wooden viewing platform above the falls provides the best vantage point for capturing the entire height of the drop.
Wear waterproof, non-slip hiking boots, as the path to the base of the waterfall becomes extremely muddy and slick.
The descent to the bottom of the falls is steep and uneven, requiring a moderate level of physical fitness.
Bring mosquito repellent, as the humid, sheltered environment of the river valley is a habitat for biting insects.
Do not attempt the descent in flip-flops or open-toed sandals; do not swim in the base pool as the current and hidden rocks make it hazardous.
Stick strictly to marked trails to protect the delicate soil and native flora; avoid disturbing the quiet environment.
