Korea's Newest Travel Trends: City Hikes, Butter Tteok and the Open-Run (2026)

Korea's trends now change in months, not years. The ones worth your autumn 2026 trip: Seoul's mountains with rented boots and free guided hikes, the chewy dessert wave led by butter tteok, and the convenience-store aisle where trends land first.

Quick answer: Two trends lead a Korea trip in autumn 2026. Visitors are hiking Seoul's own mountains, Bukhansan, Bugaksan and Gwanaksan, using city hiking centres that rent gear and run free guided hikes in English and Japanese. And Korea's dessert craze has turned chewy: Mega MGC Coffee's butter tteok, a 1,400 won baked rice cake, sold more than 5 million in four months and stays on sale through December 2026, while convenience stores copy the texture. The Dubai chewy cookie queues of early 2026 are over.

Key takeaways

Seoul's mountains are the new must-do: three hiking centres open 09:00 to 18:00, rent boots, poles and backpacks, and each closes one weekday.
Butter tteok is the dessert of the moment: crisp outside, chewy inside, 1,400 won at Mega MGC Coffee, on sale through December 2026.
Convenience stores carry the trend cheaply: CU, GS25 and 7-Eleven all sell chewy breads and bars.
Korean food fads now last months. Queue for the current one, not the one your feed showed in spring.

You saved a video of people queueing two hours for a pistachio cookie in Seoul, booked the flight, and arrived to find it on every cafe counter with no line at all. Korea's trends now turn over in months: a Korean business daily described dessert fads that once lasted years now changing almost monthly. Korea also drew 17.11 million foreign visitors from January to September 2026, up 21.5%. Here are the trends that are live this autumn, where to find them, and when to skip.

Why are visitors hiking Seoul's mountains?

Few capitals have granite peaks reachable by subway, and visitors have noticed. Seoul's hiking tourism centres counted 101,290 visitors in 2025, 18.5% of them from abroad, and 98% of foreign users said they were very satisfied. The centres rent hiking boots, poles, crampons and backpacks, offer lockers and a lounge, and run free guided hikes with English and Japanese guidance.

Centre	Address	Hours	Closed
Bukhansan	5F, 52 Samyang-ro 173-gil, Gangbuk-gu	09:00 to 18:00	Mondays
Bugaksan	1F, 88 Samcheong-ro, Jongno-gu	09:00 to 18:00	Tuesdays
Gwanaksan	B1, inside Gwanaksan Station, Gwanak-gu	09:00 to 18:00	Wednesdays

Gear is booked through Klook listings linked from the official site. Bugaksan is the gentle pick, along the old fortress wall above Samcheong-dong; Bukhansan is the serious one, and the mornings are best. Skip it if you have one day in Seoul and trainers with no grip: granite is slippery when wet, and the mountain will still be there next trip.

What is the dessert everyone is eating now?

Butter tteok. It began as a Shanghai bakery trend in early 2026: glutinous rice dough baked in butter, crisp outside and chewy inside. In Korea the mass version is Mega MGC Coffee's Butter Tteok, launched in April at 1,400 won. The chain says it sold more than 5 million in four months, and it extended sales from August through December 2026, Korea JoongAng Daily reported on 8 September.

Two related fads you will meet:

The Dubai chewy cookie (dujjonku): pistachio and kataifi in a chewy cookie, with one to two hour waits at its peak from late 2025 to February 2026. It is everywhere now and the queues have gone.
Agjak cake: fruit-shaped mousse cakes in a thin chocolate shell that crack when you bite. Korean media reported open-run queues for them in July 2026.

Skip the queue if a chain sells a version two doors down. With butter tteok, the 1,400 won coffee-shop one is the trend; the 40-minute bakery line is optional.

What should you grab at the convenience store?

Korean convenience stores turn trends into cheap products within weeks, so the chewy wave is on the shelf now, according to Korea JoongAng Daily in September 2026:

CU: Yellow Cheese Chewy Bread, and a sticky rice cream bread made with Yonsei Milk.
GS25: Breadique, a cream bread with a whole rice cake inside, and Lalasweet chewy ice bars in melon and mango, which sold over 4 million in three months after their May launch.
7-Eleven: chewy breads shaped like potatoes and sweet potatoes.

Skip it if you are after craft: these are fun, cheap snacks for the hotel fridge, not bakery quality.

What is an open-run, and when is it worth it?

Open-run (opeun-reon) is the Korean word for queueing before opening to buy a limited item. It is how you get the bakery's 130 pieces before they go, and also how you lose a morning. The rule that holds: open-run for something only that shop makes, on a weekday, and never for a product a chain already copies.

The best places to try it are the neighbourhoods Seoul is talking about this autumn, Jongno 3-ga and Seongsu. One date to keep in mind if your trip runs into the new year: the K-ETA exemption for 22 countries and territories ends on 31 December 2026.

How do you stay online on the trail and in the queue?

A trail map with no signal, a Klook gear booking, a bakery's Instagram sell-out notice: these trends run on mobile data. Buy and install a travel eSIM at home on Wi-Fi, keep your home SIM on for bank codes, and switch the travel line on after landing.

One option is the Fizen South Korea eSIM on LG U+, 4G and 5G (catalog checked 26 October 2026). Fixed plans run from 1 GB for 3 days to 50 GB for 30 days and slow to 128 kbps once used up; unlimited plans run 3 to 30 days with no speed cap stated. Most plans cannot be topped up, so size it for the trip: 10 GB for 7 days covers a week of maps, bookings and summit photos, and plenty of video points to unlimited. Check the eSIM tab in the app or fizen.io/esim for current plans for South Korea.

If a verified fault on Fizen's side stops the eSIM working, you get a free 1-for-1 replacement for the length of the trip, or a refund for the days you could not use, handled by a real person in chat. Changed plans? An unused, not-yet-installed eSIM can usually be taken back; eligibility depends on the plan, check Package details or ask chat. The honest alternative is a local prepaid SIM if you need a Korean number for verification codes. New users get US$10 of eSIM credit in the Fizen app's eSIM tab.

Sorted, the trip looks like this: Bugaksan's wall at 9am with the route on your phone, and a 1,400 won butter tteok on the way down.

Frequently asked questions

Can tourists rent hiking gear in Seoul?

Yes. Seoul's hiking tourism centres at Bukhansan, Bugaksan and Gwanaksan rent boots, poles, crampons and backpacks, open 09:00 to 18:00, and each closes one weekday. Bookings go through Klook listings linked from the official site.

What is butter tteok?

A glutinous rice cake baked in butter, crisp outside and chewy inside, which spread from Shanghai to Korea in 2026. Mega MGC Coffee sells it for 1,400 won and has extended sales through December 2026.

Is the Dubai chewy cookie still popular in Korea?

It is widely sold, but the long queues peaked between late 2025 and February 2026 and have faded. Chewy desserts like butter tteok are the current trend.

What does open-run mean in Korea?

Queueing before a shop opens to buy a limited product. It is worth it for items only that shop makes, on weekdays; skip it for products chains already copy.
