Circuit secret Porrentruy
Porrentruy has a knack for weird stories, and the Circuit Secret turns that into a walkable experience. You get a badge and the feel of being the keeper of the keys, moving through unusual spots in the castle and the older streets, with sound and light scenes bringing the tales to life.
I especially like two things: first, the tour structure makes you wander instead of sit, so you see more of town in just 2.5 hours. Second, the stop at the Musée du PIRE by Plonk and Replonk adds a playful, creative angle that fits right into the theme.
One consideration: it is not suitable for visually impaired people or wheelchair users, so plan for stairs, steps, and tight spaces that come with secret-door exploring.
Key things I’d plan around

- 11 secret places to find around the castle and in the old part of town
- Old castle prison visit, which adds a darker tone to the fun
- Sound and light productions for key historic and mythical moments
- Musée du PIRE by Plonk and Replonk included, so you leave with art ideas too
- Badge rental includes info at the Jura Tourisme desk, so you start organized
- The badge can also help with a two tickets for the price of one bonus at the Hôtel-Dieu museum
Why Porrentruy’s Secret Circuit feels like a story you can walk

This tour works because it treats the town like a set, not a museum. You do not just read about Porrentruy, you move through it, opening doors and discovering places that most people would never think to try.
And the theme is smart. It blends local political drama with folklore and a wink at imagination. Pierre Péquignat, the rebellious representative who challenged the prince-bishop, is part of the story. So is the wyvern, a mythical creature tied to water’s energy. Even the idea of dinosaurs haunting town becomes part of the playful myth mix, the sort of detail that keeps the experience from turning into a dry lecture.
The result is an outing that feels made for real time travel, not just sightseeing. You are walking, listening, and looking for clues, which is exactly how a place like Jura rewards your attention.
Badge pickup at Jura Tourisme: start here, then go confidently

Before you even reach the “secrets,” you do the one logistical thing that makes the whole experience easier: you pick up your badge rental and information at the Jura Tourisme reception desk in Porrentruy, Rue du 23-Juin 20.
That matters because the badge is not just a ticket. The tour concept is built around having a role, the keeper of the keys. When you have the badge in hand from the right place, you can focus on the route and the storytelling, instead of figuring out what to do next.
If you’re the kind of traveler who likes to get bearings fast, this is a good setup. It also means you can ask basic questions right away at the information desk, which is helpful when you want to keep moving.
The 2.5-hour route: how you cover 11 secret places without rushing

The experience runs about 2.5 hours, and it is designed to fit into a normal day of exploring Porrentruy. Starting times depend on availability, so check what works with your schedule.
The tour includes 11 secret places total, spread between:
- unusual points around the castle
- unusual points in the old part of town
Because the specific locations are “secret” by design, you should think of the stops as a guided sequence of discoveries rather than named attractions you can research ahead of time. Practically, that means you should give yourself a calm pace and be ready to slow down when something unexpected appears.
What each area gives you
Castle area: Expect more “inside-access” vibes. This is where doors, rooms, and tucked-away spaces usually do the most work. It’s also where the mood turns cinematic, since the story themes line up well with stone walls and echoing halls.
Old town area: This is where the experience becomes more human-scale. You shift from castle atmosphere to street-level atmosphere, and that contrast helps the tour feel varied rather than repetitive.
A small practical note: since you are moving between the castle and old town, wear shoes that handle uneven ground. The tour is short, but it still involves walking as you hunt for each of the 11 stops.
Sound and light scenes: Pierre Péquignat, the wyvern, and town myths

At some point during the tour, light and sound productions illustrate historic events. This is where the circuit concept becomes special, because the technology does not replace your exploring, it frames it.
Here are the themes woven into the show elements:
- Pierre Péquignat and the struggle against the prince-bishop
- the wyvern, the mythical creature associated with water’s energy
- playful, spooky-cute myths, including the idea of dinosaurs still haunting Porrentruy
The reason I like this format is simple. You are not just being told facts. You are standing in (or near) the places those stories feel connected to, and the sound and light give you a “now I get it” moment.
If you’re traveling with kids, or if you just prefer stories over timelines, this style tends to work well. Even adults who want facts usually appreciate that the scenes help you remember what you just saw.
Visiting the old castle prison: a darker pause that makes the tour feel real
One of the clearest highlights in the experience is the old castle prison visit. This is not a random stop. It gives the tour weight, and it helps balance the more playful mythology and creative museum component.
The prison setting tends to change your listening too. When the story world turns darker, you pay attention differently. Sound cues and dramatic storytelling land harder in stone spaces, and the shift in tone keeps the 2.5-hour circuit from feeling like one long mood.
Practical tip: treat this stop as a reset. If you’ve been walking and scanning for secrets, use the prison segment to slow down, look around, and let the tour’s tone shift without multitasking.
Musée du PIRE by Plonk and Replonk: where the theme turns creative

The circuit includes a visit to the Musée du PIRE by Plonk and Replonk. That inclusion is a big deal for value, because it adds an art and imagination outlet right after the “mystery walking” part.
Plonk and Replonk are known for playful, imaginative creativity, and the museum visit fits the circuit’s blend of myth and storytelling. You are basically moving from an engineered story experience into a space where art and odd ideas are the point.
If you like experiences where the last part is not just more sights, but a mental change of pace, this museum stop helps. It also makes the circuit a stronger bet if you’re traveling as a group with mixed interests, because not everyone wants strictly historical storytelling.
The bonus: badge benefits for the Musée de l’Hôtel-Dieu

Your Secret Circuit badge does more than run the circuit. It also entitles you to two entrance tickets for the price of one to the Museum de l’Hôtel-Dieu.
This is worth thinking about if you plan to keep exploring after the 2.5 hours. It effectively reduces the cost of an additional stop, which can make your day feel more efficient.
Just make sure you time it so you still have energy. The circuit itself is short, but it is active. If you stack too many museums back-to-back, the best part of the experience is lost.
Price and logistics: $16 for 2.5 hours is strong value

At $16 per person for about 2.5 hours, the value is solid, especially because:
- you get 11 secret places (not just one or two big sights)
- the circuit includes the old castle prison visit
- you also get the Musée du PIRE included
- you get the badge bonus for the Hôtel-Dieu museum
In plain terms, you are paying for a mix of performance-style storytelling plus a real museum visit. That combination usually costs more when you book separately.
One more logistics note: you can also book it with a guide. If you prefer a human voice and questions during the route, this option can be a good fit, though you would need to check how that booking works with the provider.
Who should book, and who should skip it

This circuit is a good match if you want:
- a short, active way to see Porrentruy’s castle area and old town
- storytelling that uses sound and light to connect myths and historical events
- an add-on museum visit that keeps things fun rather than strictly academic
- an experience that can work for families, since it has shown itself to be enjoyable for children in at least one family-sized outing
It is not a fit if you have accessibility needs related to vision or mobility. The operator information says it is not suitable for visually impaired people and wheelchair users.
Also, if you dislike walking routes that involve finding multiple stops, you might find it stressful. But if you enjoy the chase part, this is built for you.
Final call: should you book Circuit Secret Porrentruy?
I’d book it if you like experiences that feel like you’re in a story, not just reading signs. The 11 secret places, the old castle prison stop, and the included Musée du PIRE give you three different flavors of “what this town is like,” all within about 2.5 hours.
I would skip it if accessibility is a concern or if you want only well-lit, straightforward sights with no secret-door exploring. And if you need a strictly chronological history lesson, this circuit gives you story scenes and mood first.
If you have half a day in Porrentruy and want a memorable, low-cost plan that keeps you moving, Circuit Secret is an easy yes.
