The Tobas de Colores are popularly known online as “Barranco de las Vacas”, but the famous narrow section is actually part of Barranco de Barafonso. Agüimes Town Council identifies it as a small, narrow stretch of roughly 50 metres, formed from volcanic ash and other pyroclastic deposits that were later sculpted by running water.
The result is a photogenic corridor of smooth, layered rock in warm ochre, orange and brown tones. It is a beautiful place, but it is also a natural ravine rather than a managed tourist attraction.
Why are the Tobas de Colores so unusual?
Volcanic layers shaped by water
The walls were created from accumulated volcanic ash and other pyroclastic material. Over a very long period, water running through the ravine carved the softer deposits into flowing curves and exposed the layered colours visible today.
This is why the place is sometimes compared visually with slot canyons elsewhere in the world, although the formation here is much smaller and distinctly Canarian in origin and landscape.
What the visit is really like
This is not a long canyon hike or a developed attraction. The famous section is short. The interest is in walking into the narrow formation, seeing the textures and shapes close up, and taking time to photograph the changing curves and colours.
Access and parking
Do not treat the road shoulder as a car park
The Tobas de Colores are close to the GC-550 road towards Temisas, but the site does not have a formal visitor parking area. The popularity of the location has created repeated traffic and pedestrian-safety concerns.
Agüimes Town Council has recommended leaving vehicles properly parked in the urban area and accessing on foot rather than creating congestion beside the road. At a minimum, never leave a vehicle where it obstructs traffic, visibility, cyclists or emergency access.
Wear closed shoes with grip: the ground is natural, uneven and dusty, and the ravine floor can become slippery when wet.
When should you visit?
- Avoid rainy weather: do not enter barranco channels during rain or when significant rain is forecast.
- Prefer quieter periods: weekends can bring much heavier traffic and visitor numbers.
- Allow extra time: the ravine section is short, but safe access and finding a legal place to leave the vehicle can take longer than the visit itself.
- Take water and sun protection: the surrounding landscape is dry and exposed even though the slot itself can be shaded.
Where are the Tobas de Colores?
They are in the municipality of Agüimes, close to the GC-550 road towards Temisas. Remember that searching for “Barranco de las Vacas” may show a wider ravine name; the coloured slot itself is in Barranco de Barafonso.
Respect the place
The Tobas de Colores are a fragile natural formation. Agüimes has previously had to carry out cleaning work in the area because of rubbish left by visitors. Take everything you bring with you, do not scratch or mark the walls, and avoid climbing on formations simply to take a photograph.
