Review: Phantom Peak's JonaCon (Spring 2025)

Writer's picture: Immersive RumoursImmersive Rumours

The exceptionally well-crafted Phantom Peak delivers another outstanding season of open-world adventures with JonaCon.


With JonaCon, Phantom Peak has entered its 12th full season since opening in Summer 2022. An open-world immersive experience that invites visitors to engage with the numerous residents of the town, interact with off-kilter pieces of tech and solve puzzles while completing any or all of each season's 10 new trails. It's pretty much the closest thing you can get to stepping into a real-life video game and it continues to one-up itself season after season. With probably their strongest set of story trails yet, Phantom Peak has never been better (though we've been saying that with basically every season since it first opened..).

While Phantom Peak's Autumn and Winter seasons have always been tied to the real-life events we have 'over the ridge' with Hallowed Peak and Wintermas, Spring and Summer are when the show's creative team can let loose with their own, original overarching themes. Previous seasons have featured the Platypus Parade, which saw the opening of Platyworld, a platypus-themed exhibition (which was actually a front for JonaLabs) and The Festival of Innovation, which had the town's residents presenting bonkers inventions such as The Fear Finder and ProstleBot in a science fair-style competition. JonaCon may be their most out-there theme yet...


After tense negotiations and after bidding well over the odds, Phantom Peak has been chosen as the host town for JonaCon, a convention-cum-celebration of JONACO's head honcho, Jonas. There's a lot worth celebrating too - with JONACO recently having mounted a successful mission to space, mended relations with Wintermas demigod Father Platmas, and seemingly thwarted an attempted uprising from anti-JONACO group The Resistance in recent seasons. Huge banners adorn the town's main square, paying homage to the Sun Daddy himself, and groups of tourists have taken to cosplaying as Jonas to really get into the spirit of the convention.

By way of summary for those new to Phantom Peak, the town used to be home to a local company, Miramine, which mined for a powerful substance called Diamant below the surface of the town. Following the unexpected death of sausage-fingered Mayor Furbish in a blimp crash, Jonas and JONACO swooped in and ousted Miramine. With them came a series of innovations and changes throughout town that are still present today. While some townsfolk love Jonas and all he's done for the town, others remain sceptical. There's a boatload more backstory we could explain, but this review would be 15,000 words long, and that's all you really need to know if you're a first-time visitor.


As previously mentioned, Phantom Peak's new set of story trails are some of the strongest they've ever created. Thanks to the regular changeover of available trails with each new season, Phantom Peak's writing team are able to incorporate and build upon the elements of the previous season guests loved the most. The standout new character from last year's Wintermas season, Sherlock Bones - a dog puppet parodying Sherlock Holmes (though surely you realised that by the name alone..) - makes a welcome return in the trail 'Bad To The Bone', which sees Sherlock battling their nemesis, Meowiarty on the cliffs of the Reichenbark Falls in dramatic Punch and Judy fashion. Fans of Wicked will find great delight in 'Unpopular', which features a full-length parody of the musical's song that's aimed directly at one of the townsfolk, Perigate, who has long grappled with their position in the town's social hierarchy.

Elsewhere in town, Phantom Peak's Videomatic machines, which play pre-recorded video content when a valid 4-digit code is correctly entered, have some exceptionally well-crafted films. We're introduced to the grandfather of long-time fan favourite Dr Winter (who looks suspiciously like Dr Winter, just in a bald cap) in 'Too Fast, Too Furrious', and a tense recreation of a basketball game made with a cast of puppets and a selection of the show's gift shop plush toys as a crowd in 'Winner Takes It All', delivers some of the season's biggest laughs.


Phantom Peak also doesn't shy away from lampooning and commenting on the world outside the show throughout its trails, touching on everything from the emotional manipulation of television show contestants in a video package for Phantom Peak's version of Great British Bake Off, to calling out the likes of Mr. Beast for their use of young children's attention for monetary gain.

Every trail zips along at an enjoyable pace, providing plenty of opportunities to interact with Phantom Peak's various townsfolk, who are the backbone of the experience. With a cast fully committed to improvising and responding to whatever they're being asked by tourists, every interaction with the town's residents is a delight. As with so many immersive experiences, the more you put into it, the more you'll get out of it, so don't shy away from interacting with the show's cast whenever you get a chance, even if they're not directly tied into the trail you're working through.


With a very generous 4+ hours to explore the town every session, Phantom Peak allows guests to take things at their own pace. There's no danger of missing any big set-piece moments while in the town, as each trail's pace is driven entirely by however fast or slow any given group decides to work through the storylines. There are also plenty of distractions to pull guests away from the main storylines, with a fully functional arcade, a trio of carnival games, a bar with an extensive menu of cocktails and numerous food options courtesy of RoboChef, and add-on experiences including a Cocktail Experience and Puzzle Hunt.

Late last year, when the pre-sale for this Spring season of Phantom Peak first opened, it was announced as the final season of Phantom Peak at their current Canada Water home. Since then, they've managed to secure an extension at their massive 30,000 sq. ft venue, with the previously planned final season now on hold for a little while longer. The team behind the show are currently working on locking in a new location for the show elsewhere in East London, seemingly confirming that the world of Phantom Peak has a lot of life left in it yet.


Regular readers of Immersive Rumours will know our feelings on Phantom Peak have never wavered. It's the best immersive experience London has to offer and is the crown jewel in the city's immersive scene. An unrivalled experience that continues to deliver season after season, Phantom Peak is deeply rewarding for both first-time visitors and die-hard fans. Praise Jonas!
