Cafe Pokpo Waterfall in Seoul: Hongjecheon Park Guide

The highway overhead makes no apologies. Neither does the waterfall.

There are places in Seoul that feel assembled from incompatible parts — and Cafe Pokpo, sitting along Hongjecheon stream in Seodaemun-gu, is unapologetically one of them. Above the deck runs a concrete highway overpass, its undercarriage exposed and industrial. In front of it, twenty-five metres of water unspools down a moss-covered cliff face in multiple simultaneous streams, pooling at the bottom with the steady noise of something that has been falling for a long time. The fact that it is entirely artificial makes it stranger, and somehow more compelling.

This was always a civic project dressed up as a café. In 2022, Seoul City converted a disused car park and storage lot on the opposite bank of Hongjecheon into what it called its first Waterfront Sensory City — a long wooden deck terrace, a curved glass building, and a public waterfall that had previously been seasonal and undervisited. The transformation was complete enough that visitors sometimes need a moment to register that the falls, the deck, and the overpass all belong to the same frame.

The Waterfall

The waterfall operates year-round, from 8:00 in the morning until 9:00 at night — a change from earlier years when it shut down for winter months. In summer the effect is at its most overwhelming: every surface of the cliff is green, the multiple streams fanning wide before converging into the basin below, and the spray carries far enough to cool the nearest terrace seats. In early spring, before full leaf cover, the rock face is more exposed and the falls read as something starker — less garden, more geology.

The cliff is not natural. The waterfall is fed from above, engineered into a hillside that has since grown around it convincingly enough that you can convince yourself otherwise. The stream below — Hongjecheon itself, restored and reclaimed — runs clear alongside the deck and continues upstream into the quieter stretches of the valley, where a traditional wooden watermill structure still stands on a small green island mid-stream.

The Terrace and the Café

The deck runs long and wide, curving gently along the bank. Rows of dark chairs face the falls the way seats face a stage, and in the early morning or on weekdays before the crowds arrive there is something almost ceremonial about the arrangement. The café doesn’t require a purchase to use the terrace, and outside food is permitted within reason — a policy that reflects its origins as a public-good project more than a commercial one.

The café itself operates from inside the curved glass building, where ordering is done by kiosk and drinks are collected by buzzer. Americano is priced at ₩4,000, café latte at ₩4,500, vanilla latte at ₩5,000, alongside ades, teas, and light snacks. The pricing is deliberately modest — Seodaemun-gu set prices in line with nearby cafés to avoid competing unfairly, and the café’s full revenue goes toward scholarships for local university students. It is, in other words, a café that exists for reasons other than the usual ones.

At the far end of the terrace, where the elevated road comes closest and the deck narrows into a covered section, a corrugated yellow wall marks the boundary of the older structure. From here, the view compresses: waterfall framed by roofline on one side, weeping willows on the other, the stream running close enough to hear clearly.

The Bookroom

The Pokpo Bookroom Areum-in Library — Seodaemun-gu’s fourteenth public branch library — opened in September 2023 in the former annex building beside the café. It holds over 2,100 physical books alongside approximately 4,000 e-books accessible via tablets, with kiosk book search terminals and seating that opens onto the terrace. Members of the Seodaemun District Public Library can borrow books, and the library also lends picnic mats, knee blankets, low tables, and reading tents for use in the outdoor space. The combination of library and waterfall view is not something most cities would design, which is part of what makes it feel worth noting.

The interior is dark and quiet against the brightness of the deck outside. Through the full-length windows, the waterfall is visible from both levels — reflected in the glass, it doubles. Standing inside looking out, the falls look like a mural someone installed specifically for the reading room.

A waterfall built by the city, run for the people, loud enough to think through anyway.
