2026 Seoul Outdoor Library

The idea of laying beanbags on a lawn in the middle of the city and borrowing a book to lie back and read

In the heart of Seoul, colorful beanbags are laid out on the lawn square in front of City Hall, and people lie on them reading books. When I first saw it, I honestly felt a little bewildered. It was called a library, so I pictured a building, but there are no roof or walls here. Seoul Outdoor Library started at Seoul Plaza in 2022 and now runs in three locations with different concepts: Seoul Plaza (Reading Seoul Plaza), Gwanghwamun Square (Gwanghwamun Book Yard), and the Cheonggyecheon section from Mojon Bridge to Gwangtong Bridge (Reading Clear Stream). Books selected by librarians from the Seoul Metropolitan Library can be borrowed and read freely on site, and if you do not finish one, you can simply leave it there. There is no admission fee and no library card required.

The operating period is long, so as long as your schedule fits, you are set. In 2026, Gwanghwamun Book Yard and Reading Clear Stream open first on April 23, and Reading Seoul Plaza opens on May 1. It runs every Friday, Saturday, and Sunday in two seasons, the first half of the year (April to June) and the second half (September to November). Since the hottest part of summer and the monsoon season are a break, spring and autumn are the key seasons. Hours are flexibly adjusted depending on the weather, with daytime (11:00-18:00) and nighttime (16:00-22:00) operation, so before you go, I recommend checking the official website once to confirm that day’s hours.

First thing to decide: you can just go, but tours and programs have separate reservations

Let’s start with the good news. Dropping by just to read books requires no reservation at all. If there is an empty beanbag, you can just lie down and open a book, that’s it. However, special programs such as performances, film screenings, and 'book-zoning' are often run by advance application. During the opening week, band performances and movie screenings were also shown through prior registration. If there is a program you want, it is safest to check the application schedule in advance on the website.

There is something especially welcome for international travelers. Starting in 2026, the 'Seoul Outdoor Library Tour' for foreign visitors will be expanded. It is a program where you walk through Seoul Plaza, Gwanghwamun Square, and the Cheonggyecheon area, experiencing the three hubs and 'book-zoning' along the way, and it is scheduled to run 20 times in total from May to June and September to October. A dedicated English guide explains the outdoor library and the history and culture of Seoul in English, and 'Youth Partners' accompany the group to provide tourism information as well. It is designed so you can participate using only English, which is perfect if Korean feels daunting. There is also a 'Travel Library' popup with embassies and cultural centers in Korea participating, so there is the fun of casually exploring various countries’ cultures while sitting in the square.

If you want to see all three places, this route is convenient. If you get off at City Hall Station on Subway Lines 1 and 2, Seoul Plaza is right in front of Exit 5. From there it is about a 10-minute walk to Gwanghwamun Square, and the Cheonggyecheon Mojon Bridge area is about the same distance, so it is not difficult to visit all three at once. If you stay until night, it closes at 22:00, so you do not really need to worry about the last train, but the Cheonggyecheon section is by the water and gets unexpectedly chilly after sunset, so bring a light outer layer.

The mood differs at each of the three spots — a living room, a campsite, and the waterside

Even though it is the same outdoor library, the atmosphere at each of the three hubs is clearly different, so I found it fun to choose based on my mood that day. Seoul Plaza is themed as 'the city’s living room,' with beanbags where families, couples, and friends can sit together, plus a creative playground in the center of the square. It is the place with the most families bringing children. Gwanghwamun Square evokes the feeling of camping beneath a mountain slope, with camping chairs set out, while Cheonggyecheon is arranged as a calm space where you can immerse yourself alone to the sound of water. At Cheonggyecheon, they also ran 'Silent book-zoning,' where you wear wireless headsets to block out surrounding noise and focus on reading.

Combined across the hubs, the book collection totals about 12,000 volumes, and Seoul Plaza alone has around 5,000 themed books prepared. Most of the books are in Korean, but honestly the main experience here is less about 'reading' and more about 'lounging on a beanbag in the middle of the city and doing nothing for a while.' Lying on the grass with the forest of Gwanghwamun buildings in the background and looking up at the sky makes for a truly great photo. That means you can enjoy it fully even if you do not understand Korean at all. It is also a good idea to look for the English picture book or photo book section.

You can use nearby subway stations and underground shopping areas around City Hall Station and Gwanghwamun Station for restrooms, and there are plenty of cafes and convenience stores around the squares, making it easy to grab a drink and settle in. Eating on the grass is generally discouraged, so I recommend keeping it light with just a cup of coffee. Payment at nearby stores all accepts cards and mobile pay, so there is no need to carry cash separately (and since using the library itself is free, there is not much reason to spend money anyway).

Things to know so you do not make a wasted trip

The most common mistake is going on just any day. It is not open on weekdays, only on Friday, Saturday, and Sunday. And because it is concentrated in April to June and September to November, if you visit in the middle of summer or winter you will just see an empty square. On days with rain, extreme heat, or strong winds, operations may be adjusted for safety, so if the weather seems uncertain, it is a good idea to check whether it is operating that day on the official website before heading out.

Here are a few more things worth keeping in mind.

• On weekend afternoons, especially bright spring and autumn Saturdays, beanbags fill up fast. If you want a seat, aim for right after opening or late afternoon.
• Since you will be sitting and lying on the grass, comfortable clothes and sneakers are better than jeans. On sunny days, a hat or sunglasses are useful.
• The foreigner tours and popular programs may close early with first-come, first-served advance registration, so once the schedule is set, apply right away.
• During night operation, Cheonggyecheon is at its most atmospheric, but the temperature drops, so an outer layer is a must.

So who would I recommend it to?

It is perfect for anyone who wants to insert 'one hour of doing nothing' into a packed sightseeing schedule, or for those who need a free place to rest along a route connecting Gyeongbokgung, Gwanghwamun, and Myeong-dong. It is a place where you can experience the most relaxed side of downtown Seoul without spending a single won, so both solo travelers and families with children will like it in their own way. The moment you lean back on a beanbag and look up at the Gwanghwamun sky, you cannot help but say, 'Wow, this is nice.'
