Hiking the River Borosa in Cazorla

From the car park the track follows the river on a forest road. For the first stretch it shares ground with the long-distance GR-7. You cross the water more than once. The Arroyo de las Truchas joins from the side. At the stone Puente de los Caracolillos the GR-7 leaves; the Borosa path stays with the stream.

A short way on, a path drops into the Cerrada de Elias: a narrow limestone cut with wooden walkways over the water. This is the photograph most people come for. From the visitor centre it is about 4–5 km. There and back is a comfortable morning — say 8–10 km and two to three hours — on easy ground if the boards are open.

Stay on the track and you reach the hydroelectric station at the Salto de los Organos, about 7.3 km from the start. That is where the official marked sendero ends. A sign there can look like the finish. Behind the building a steeper path climbs past waterfalls, through irrigation tunnels (take a torch) and up to the small reservoir of Aguas Negras, the karst spring that feeds the Borosa, and the Laguna de Valdeazores a little further on. That extra climb is the hard part: loose stone, height and length. Plan 6–8 hours for the whole return if you go that far, and start early.

• To the Cerrada de Elias: about 8–10 km return, 2–3 hours, easy if the walkways are open
• To the power station: about 14–15 km return, 4–5 hours, moderate
• To Aguas Negras and Valdeazores: about 21–24 km return, 6–8 hours, moderate to hard because of distance

The river and the trout farm. The walk begins next to the old piscifactoria. The visitor centre sits here, not two kilometres away. You can look in on the tanks when the building is open. The river is cold even in August. (Map)

Puente de los Caracolillos. A stone bridge and a fold in the limestone that looks like a snail shell. This is where the GR-7 and the river path split.

Cerrada de Elias. The gorge. Walkways sit a few metres above the water between walls that close to a couple of metres. After winter storms this stretch is the one that closes first. There is a forest-track bypass if the boards are shut, but you lose the best of the walk. (Map)

The power station. A working hydroelectric building at the Salto de los Organos, not a museum ruin. Water drops beside it. Shade and a spring nearby make it the usual lunch stop on the medium walk. (Map)

Arroyo de las Truchas. An early side stream, not a separate hike. Good water when the season has been wet. (Map)

The Sierra de las Banderillas stands above the valley. It is a limestone ridge you look at, not a stop on this riverside path. Climbing it is another outing.

The River Borosa visitor centre is on the short lane off the A-319 at Torre del Vinagre — the same lane as the fish farm. Published addresses vary between km 47 and km 48.8 of the A-319 plus a 1.5–2 km turning. Follow the signs for “Rio Borosa” and “Piscifactoria”.

Parking is at the start. It is usually charged; published day rates change. In Easter, July and August the main lot fills before 9:30. There is no regular bus to the gate.

The path itself has no ticket. The centre is free when it is open. Hours move with the season and do not all match across official listings. Treat any printed timetable as a hint and call before you rely on the exhibition. Useful numbers in recent listings: 671 596 098 and 660 054 021 (Junta visitor window); Torre del Vinagre 953 713 017. An older local listing still shows 953 124 235.

Spring and autumn are the sensible months: water in the river, cooler air. Summer is hot on the upper track and crowded on the walkways. After a dry year the falls shrink. After heavy rain, bridges and boards can be closed — as they were in 2026 after winter storms, with a staged reopening through the summer.
