It’s a mind-boggling, suffocating heatwave. With temperatures approaching 40 degrees Celsius and soaring rapidly into the high 30s, simply stepping outside requires immense courage.
But if you absolutely have to go out, you should skip the unnecessary hassle. It’s time to head to the “best indoor retreats,” where the air conditioning fully shields you from the brutal heatwave.
Here are some tried-and-true spots where you can enjoy 100% comfort without having to face the scorching sun.
Hongdae Ice Art Cafe
Just hearing the name “Ice Art Cafe” sends a chill down your spine. You can admire magnificent ice sculptures, sip a drink served in an ice glass, and even enjoy the unique experience of smashing it to pieces. The spectacular ice-carving performance unfolding right before your eyes is an added bonus. There’s no better place to escape the sweltering heat of midsummer.
If you want to shatter the stifling heat just as you’d shatter solid ice, don’t hesitate—head straight here.
COEX Aquarium

Amid the sweltering heat, stepping outside is an adventure in itself.
COEX, which is directly connected to Samsung Station via an underground passage, is the perfect choice since you can get there without seeing a single ray of sunlight. Among its attractions, I highly recommend the COEX Aquarium, often called the ultimate indoor summer retreat. Coincidentally, they’re currently running a promotion offering a 50% discount on tickets for anyone with a birthday in August throughout the entire month.
If you want to completely block out the scorching sun and enjoy a summer escape in a cool underwater world, there’s no reason to hesitate.
Yeouido IFC Mall
It’s the perfect indoor complex where you can do everything without ever having to step outside.
With everything from movie theaters to mouthwatering restaurants, sweet ice cream shops, cafes, and bookstores all gathered in one place, it creates the perfect, seamless date itinerary. It’s the best choice for continuing your romantic adventure in comfort, whether in sweltering heat or pouring rain.
If you want to minimize the hassle of getting around while maximizing the quality of your date, this is the place!
Seongsu Sweet
It’s a cut above the rest—an ice cream experience just for adults.
In the sweltering summer heat, when even your appetite disappears, if you’re tired of the same old shaved ice or run-of-the-mill ice cream you eat every day, you need a fresh twist. “Sweet,” a “dessert for adults” in Seongsu where the rich aroma of whiskey fills your mouth, is the clear answer.
…the sophisticated flavor lingering at the end of the sweetness instantly awakens your weary taste buds.
At the Pompidou Center in Yeouido, one
This is a one-of-a-kind itinerary where you can enjoy everything from the artistic works of world-renowned masters to sophisticated dining and the skyline view from the 63 Building Observatory—all in one go. The “Pompidou Center Hanwha” in Yeouido, which opened this year…
The “Cubist” opening exhibition, where you can see Picasso’s masterpieces firsthand, is currently underway, thoroughly satisfying your cultural cravings. Plus, all amenities are seamlessly connected indoors, so you don’t have to step outside even once, even in the sweltering heat.
Seoul Art Book Report
The perfect indoor summer retreat for bookworms: “Seoul Art Book House”!
It’s more than just a place to escape the sweltering heat; it’s packed with a variety of book talks, hands-on workshops, and programs exclusively for children, all tailored for the summer season. It’s the perfect spot to spend a fulfilling day immersed in the scent of books in a cool and comfortable space.
Inspire, Yeongjong Island, Incheon
The moment you step inside, it’s a perfect indoor paradise where you can stay comfortably all day long, completely shielded from the blazing sunlight.
“Inspire” is a destination that seamlessly blends everything from gourmet dining to diverse shopping and spectacular entertainment.
In particular, the immersive exhibition “Le Space: ICE PLANET” is currently underway—just hearing its name makes your whole body feel cool—allowing you to enjoy a unique experience as if you’ve crash-landed on a distant, icy planet, completely cut off from the outside world.
It’s the perfect choice for a staycation!
