Via Ferrata Tossal de les Venes de Rojalons

The only via ferrata in Spain that finishes underground: two Nepalese bridges, an overhanging spur, and a final section threading through a cave by headlamp. Short, intense, and unlike anything else in the country.

What This Route Involves

Most via ferratas go up a wall. This one goes up, along, down — and then into the mountain. The Tossal de les Venes is the only equipped route on the Iberian Peninsula with a genuine underground section, and it has a reputation among Catalan ferratistas as one of the most imaginative routes ever built here.

It climbs the south face of the Tossal de les Venes, a modest 854-metre hill above the village of Rojals in the Muntanyes de Prades, in quiet rural Tarragona about an hour and a half from Barcelona. The cliff isn't tall — the whole route is relatively short — but almost nothing about it is ordinary. Two Nepalese bridges, one of them threading beneath an overhanging roof. A short, brutal spur where the last staple sits just far enough away to make you commit. And then a descent on chains into a crack in the rock, and a traverse through the dark.

★ The underground finish

The mountain is riddled with fissures and shafts, and the route's final section goes straight into them. A headlamp is mandatory. Inside there's a damp traverse, a vertical section on staples, and a passage so narrow you take your pack off to get through it. There are two exits — an easy one and a harder one — and there's nothing else like it in Spain.

Built for two very different climbers

The genuinely clever thing about this route is that almost every hard section has an easier twin. It starts with a choice — a friendly K2 entrance or a K4 line on bolted-on climbing holds. The overhanging spur near the top can be taken direct at K4+ or bypassed on an easy flank. Even the cave splits into an easy direct passage and a more convoluted hard one. So a strong beginner and an experienced ferratista can climb the same route on the same morning, each on their own line, and both come away satisfied. We choose section by section, based on how the group is moving.

Section by section

Approach · 20 min

A path through pine and scrub from the parking on the Rojals road, arriving at the foot of the south face.

The double entrance

Two ways in from the very first move: an accessible K2 line, or a K4 start on climbing holds bolted to the wall. This is where we set the tone for your day.

First bridge

A short Nepalese bridge, around 8 metres, passing underneath a rock roof — an unusual and photogenic position — followed immediately by a steep step and a small leap of faith.

The traverses

Long flanking sections on staples above the drop, occasionally slightly overhanging. This is where the route feels airy rather than hard, and where an escape route exists if the group needs it.

Second bridge

A longer crossing, around 12 metres, then a vertical wall with a bulge at the top to keep the forearms honest.

The spur (K4+)

Short and genuinely hard: an overhang with the final staple deliberately out of reach, so you use the rock. Optional — the easier flank at K3 reaches the same summit.

Down to the dark

From the top of the Tossal, chains and steps lead back down to a fissure in the rock. Last chance to walk out — or clip in and go underground.

The cave

Headlamps on. A damp traverse where the footing is slick, a vertical pitch on staples, and a squeeze narrow enough that packs come off. Two exits: straightforward, or awkward and brilliant.

Return

A short marked path back past the start of the route to the parking.

⚠ Is this route for you?

Let's make sure you have a great time! The cave is genuinely tight and dark, so this is not a route for anyone claustrophobic, though it can be skipped entirely and the rest of the ferrata still makes a great morning. And the rock and steps here are abrasive; gloves aren't a suggestion on this one. We carry a rope and back up the harder overhangs, but the route rewards people who arrive with some fitness in their arms.

A note on the setting

This route sits in a quiet natural area and the caves in particular are fragile. It has been closed and reopened more than once as the equipment has been renewed — most recently with an added lifeline before the underground section. We climb it respecting the environment and the installations, which is what keeps it open for everyone. Combine the morning with lunch in medieval Montblanc, fifteen minutes away, and you have close to a perfect day out.

Before You Book: Requirements & FAQs

The cave, the bridges, the variants and the practicalities — everything people ask about this route before committing.

The cave
Is the cave section claustrophobic?
Honestly, yes, for some people. It's a real underground traverse by headlamp, with a damp section where the footing is slick and a passage narrow enough that you take your pack off to get through. If confined dark spaces bother you, this part isn't for you — and that's a perfectly normal thing to say when you book.
Can I skip the cave and still do the route?
Yes. The underground section comes at the very end, after the summit, and there's a clear point where you can walk out instead and take the return path. You'd still have done two Nepalese bridges, the traverses and the spur — a full and satisfying morning. Nobody is talked into going underground.
Do I need a headlamp, or do you provide one?
We provide headlamps for everyone, along with all the technical equipment. A light is genuinely mandatory in there — it's properly dark, not dim — so this isn't a section anyone improvises with a phone torch.
What's the cave actually like inside?
The mountain is riddled with fissures, and the route threads into them. After a first common section it splits: an easy, direct passage, or a more convoluted harder one. Expect a damp flanking traverse, a vertical pitch on staples, and one genuine squeeze. It's the part everyone talks about afterwards.
Difficulty & variants
Is this route suitable for beginners?
A fit and confident first-timer can do it with a guide, because almost every hard section has an easier twin — including the very first move, which offers a friendly K2 entrance or a K4 line on bolted climbing holds. That said, if this would be your very first via ferrata, Baumes Corcades is a gentler and more forgiving introduction, and we'll say so honestly.
How hard is the K4+ spur?
Short and genuinely demanding: an overhang where the last staple is deliberately placed out of easy reach, so you have to use the rock itself. It's the hardest move on the route. It's also entirely optional — an easier flank at K3 reaches the same summit, and we back the hard line up with a rope for anyone who wants to try it.
Are the bridges compulsory?
The two Nepalese bridges are part of the main line, and the first one — around 8 metres, passing beneath a rock roof — is one of the more unusual positions in Catalan ferrata. They're not difficult, but they are exposed. If someone in the group is genuinely unhappy about a bridge, tell us early and we'll work out the day around it.
How fit do I need to be?
Moderately fit is enough for the easier variants; the harder lines ask for real arm strength, particularly at the start and on the spur. The route is short, so it's about intensity rather than endurance. If you can walk uphill for twenty minutes and pull yourself up a ladder a few times, the K2/K3 line will suit you well.
Practical
Where is it, and how do I get there from Barcelona?
The route is on the south face of the Tossal de les Venes, above Rojals in the Muntanyes de Prades, near medieval Montblanc in Tarragona province — around an hour and a half from Barcelona by car. We park on the Rojals road and walk in for about twenty minutes. Full meeting details come with your booking.
Do I really need gloves?
Yes, more than on most routes. The rock and the steps here are noticeably abrasive, and there's a lot of hand contact over a few hours. Any decent pair of work or via ferrata gloves will do, and your hands will thank you at the end.
When is the best time to go?
Spring and autumn are ideal. It works in summer too, since the wall is short and the cave section stays genuinely cool — a real advantage on a hot day when other ferratas are unpleasant. Winter is fine when it's dry, though the cave is damp year-round and cold hands make the abrasive steps less fun.
Can we combine it with lunch in Montblanc?
Yes, and it's the standard way to finish. Montblanc is a walled medieval town about fifteen minutes away with plenty of places to eat. The route is short enough that a morning start leaves the whole afternoon free — tell us when you book and we'll set the timing around it.
How big is the group?
A maximum of six climbers per guide. On a route with this many variants that matters, because we're choosing lines for individuals rather than herding a group along one path. For larger groups we can run more than one guide — just tell us numbers and dates early.
What's your cancellation policy?
If weather or rock conditions don't allow the activity to go ahead safely, we reschedule or propose an equivalent alternative, and if neither works you receive a full refund. Free cancellation up to 7 days in advance. We don't run via ferrata in rain — wet steel and a damp cave are a poor combination.
Not sure this is the one?

If this would be your first via ferrata, Baumes Corcades is a gentler introduction with escape options throughout. If the K4+ spur sounds like the good part, Cágate Lorito is the hardest ferrata we guide.
