Summer in Seoul is a time of hot weather, humidity, and abundant sunshine. It is also a time for festivals, outdoor activities, and delicious food.
Embarking on a summer voyage to Seoul? With soaring temperatures, the South Korean capital transforms into a vibrant hub of adventure, culture, and stunning scenic beauty. Discover the myriad of things to do that make summer in Seoul an unforgettable experience.
Rejuvenate at Han River
When the summer sun blazes, finding respite becomes necessary. The Han River emerges as a serene retreat to beat the heat and chill with companions. Revel in the picturesque summer beauty while lounging on rented mats, or indulge in a picnic with delectable delights available from local food stalls or even delivered directly to your spot!
Consider stocking up on some picnic essentials before heading to this calming riverside. The mesmerizing sunset by the river makes for a prime Seoul summer spectacle, one not to be missed!
The Han River is a popular destination for summer boat rides. You can rent a boat, explore the river at your own pace, or take a guided tour.
Explore the Gastronomical Alleys
Renowned for its culinary repertoire, Seoul is teeming with vibrant food markets, including Gwangjang, Dongdaemun, and Tongin. Teeming with local delicacies ranging from “mayak gimbap” to “bindaetteok”, these bustling food havens offer an immersive taste of Korean culture and are essential additions to your “summer in Seoul” itinerary. Vendors are selling all sorts of delicious food, from Korean staples like bibimbap and kimchi to international dishes like pizza and pasta.
Dive into the Richness of Korean Culture
If you’re seeking indoor refuge from the intense summer warmth, Seoul’s air-conditioned museums and galleries make for perfect destinations. Unravel the stories of traditional Korean life at the National Folk Museum of Korea, or delve into modern artistic expressions at the National Museum of Modern and Contemporary Art. The abundance of intriguing exhibits makes a museum visit an enriching addition to your summer activities.
Immerse in Seoul’s Vibrant Nightlife
A city known for its lively nocturnal scene, Seoul is a delight for night owls. The city’s pulsating energy is not confined to weekends, with clubs and bars staying open until the wee hours. Enjoy a sip of soju and brace yourself for an unforgettable night.
Distinct areas like Hongdae offer a lively underground music scene with affordable drinks, perfect for students, while Itaewon caters to a broad demographic with foreigner-friendly clubs and rooftop bars. A night out in Seoul’s divergent nightlife zones is an essential summer experience.
Late-night Bingsu Crawl
Warm Seoul nights practically beg for shaved-ice sugar jolts, and the city rewards insomniac sweet-tooths with cafés that stay open long after the last bar call.
You can start off in student-heavy Sinchon with Homilbat’s nothing-but-the-basics pat-bingsu. The shop’s ultra-fine milk ice dissolves like snow on your tongue, and the red-bean topping is cooked fresh every morning. Doors close at 22:00, so arrive by nine to slurp unhurriedly before the last ladle of red bean is gone.
Another one that you can explore is the Sulbing’s flagship branch that never sleeps. If the queue looks brutal, order at the self-kiosk and people-watch while K-pop blasts overhead: the shop is designed for late-night lingerers, with phone chargers available at almost every table.
To keep the crawl fun rather than sugar-induced overload, plan on sharing each bowl, every café’s dishes portions meant for two, so splitting lets you taste more without a crash. Make sure your wallet is ready for a cash-free night: T-Money and credit cards are accepted everywhere. Sulbing switches to kiosk ordering after 11 p.m., which means transactions are only accepted by card. And if you are out late at night, pay close attention to the clock for the last subway trains. If you linger past that, be ready to catch one of the blue night buses or spring for a taxi.
Experience Thrills at Theme Parks
For a dash of adrenaline-fueled fun, a visit to Seoul’s theme parks makes for an exhilarating summer day out. With a blend of rollercoasters, water rides, games, and VR zones, Lotte World and Everland stand out as fun-filled hotspots. Whether escaping the summer heat at Lotte World, the largest indoor theme park in the world, or venturing into Korea’s largest theme park, Everland, a day of thrilling excitement awaits.
And You Can’t Forget the Water Parks
You can start with Caribbean Bay, the aquatic wing of Everland Resort in Yongin. From central Seoul, the most seamless route is the Bundang-line subway to Giheung, a hop onto the driverless EverLine, and a free five-minute shuttle straight to the entrance. If the trains sync up, it’s about an hour and a quarter door-to-gate. Inside, make a beeline for Mega Storm, a 37-metre funnel slide, or drift over to the outdoor wave pool where two-metre swells roll every few minutes. And if it’s a rainy day, then you can duck into the all-weather Aquatic Center.
If you crave even bigger slides, head northeast to Vivaldi Park Ocean World in Gangwon-do’s pine-covered foothills. Most travelers opt for a 90-minute shuttle from Myeong-dong or Hongdae, although the ITX-Cheongchun to Gangchon, followed by a short taxi ride, is also a viable option. Highlights include the half-pipe Super Boomerango, the kilometre-long Cairo River lazy river, and the trio raft Monster Blaster. After conquering the slides, soothe sore calves in the “Spa Village” jjimjilbang.
