A Korean mountain in deep winter is not built for company. The rock turns the colour of cold pewter, the pines carry their snow like something they would rather set down, and the light goes flat until a whole ridge reads as one grey plane — broken only by four small, brightly dressed, visibly unwilling figures working their way up it. Those four are the reason to watch Take a Hike!, the new Korean reality show Netflix is releasing worldwide, and the show’s first honest gesture is to admit that none of them wanted to come.

The premise is a joke told with a straight face. Four celebrities who have no interest in hiking form a club — a hasan-akhoe, a ‘descent society’ — whose entire reason for existing is to come back down a mountain, which first, inconveniently, requires going up one. The founders are the singer Car, the garden; Dowoon, the drummer of the band DAY6; the actor Lee Chae-min, fresh off Bon Appétit, Your Majesty; and Tarzzan, the rapper and dancer from the rookie group ALLDAY PROJECT. On paper they share almost nothing: different ages, different crafts, different audiences. That is the casting logic, not a flaw in it. Put four people who would never otherwise stand on the same ridge onto the same one, in the cold, and watch what they turn into.

Behind them stands Na Young-seok, the most durable director in Korean variety, working here alongside Park Hyun-yong. For two decades Na has run the same quiet machine across shows like 1 Night 2 Days, Three Meals a Day and New Journey to the West: take performers out of their comfort, hand them a real task and real weather, and let the discomfort do the writing. He does not build spectacle; he waits for people to stop performing. A winter mountain is almost too neat a setting for that method. There is no green room at two thousand metres, and the cold does not negotiate.

In the trailer, that plan is already visible in outline — bright parkas against white slopes, breath hanging in the air, four faces cycling through the specific expressions of people realising, in real time, that they have agreed to something harder than it sounded in the meeting. It is a familiar look for anyone who has been talked into a winter walk by a more enthusiastic friend. Here, the more enthusiastic friend is the format.

What makes that format worth a second look is what it refuses to be. This is not a competition. There is no prize, no elimination, no leaderboard — none of the manufactured stakes that power most streaming reality. Physical: 100 turned Korean bodies into a tournament and made a global hit of the spectacle; Take a Hike! points in the opposite direction. The outdoor-variety tradition it belongs to measures success in smaller units: a shared snack, a bad joke that finally lands, someone deciding not to turn back. Its wager is that those units are enough. The mountain is not an obstacle to be conquered. It is simply there, indifferent — and the show is unusually honest that indifference is most of what a mountain has to offer.

That honesty reads differently in Korea than it would anywhere else, because hiking there is not a neutral pastime. It is generational. Weekend trails fill with hikers in their fifties and sixties in full technical kit, and to the twenty- and thirty-somethings this cast belongs to, the whole pursuit lands as faintly, endearingly uncool — close to the most ‘ajusshi’ hobby the country has. Dropping four young, style-conscious celebrities into that world is its own small comedy of manners. They are doing the thing their parents do, badly, on camera, and the distance between how they picture themselves and what the mountain actually asks is the show’s real engine.

The platform choice carries its own argument. Na Young-seok made his name on Korean broadcast and cable, building formats for a domestic audience that already knew his rhythms by heart. Bringing this one to Netflix — with an English-subtitled trailer pushed out through Netflix’s Korean-content channels — is a bet that his particular register of slow, warm, low-stakes variety can travel the way scripted K-drama and the harder edges of Korean unscripted already have. It is the sort of show a global platform does not obviously need and becomes interesting for choosing anyway: a quiet one, in a catalogue built to reward noise.

It helps that the four names were chosen to reach in four directions at once. Car, the garden brings the wry, lived-in presence of a musician who has already shown he can carry unscripted television; Dowoon brings the steadiness of a working band drummer and a large, devoted DAY6 following; Lee Chae-min arrives with the momentum of a young actor whose recent work has put him in front of a wide drama audience; Tarzzan brings the newest energy of the group, an idol-generation performer with an audience that barely overlaps the other three. None of that overlap is accidental. The show is engineered so that whoever you came for, you leave having watched the other three.

Which returns everything to the question the title keeps asking and never answers. Why hike at all? Why choose the cold, the altitude, the aching legs, when nothing at the summit requires you to be there? The four reluctant members are the audience’s proxies in that argument, and the honest version of the answer is that there may not be one — that people climb for reasons that dissolve the second they try to say them out loud. A lesser format would settle it with a summit and a swell of strings. This one looks built to leave the question exactly where it found it: somewhere on the way up, in bad weather, in company nobody chose.

Take a Hike! begins streaming on Netflix worldwide on 18 August 2026, with subtitles. Na Young-seok and Park Hyun-yong direct; the descent club’s four founding members are Car, the garden, Dowoon, Lee Chae-min and Tarzzan. The mountains are real, the winter is real, and by the cast’s own account, so is the reluctance.
