Seoul is filled with well-known tourist attractions, but when I began searching for places that weren’t already famous yet consistently received positive reviews from foreign travelers, the results were surprising. The places that visitors described as “unexpectedly amazing” were completely different from the typical hotspots most people imagine.
Many travelers shared that while major landmarks and shopping districts are enjoyable, what stayed with them long after their trip were the quiet parks, riverside paths, forested trails, and peaceful walking routes hidden throughout the city.
Looking through reviews on Reddit, YouTube, and TripAdvisor, I repeatedly encountered comments such as:
“I had no idea a place like this existed in Seoul,”
“There were almost no tourists, which made it even better.”
This article is the first of a three-part series introducing 15 underrated places in Seoul frequently praised by foreign travelers. In Part 1, we’ll explore five quiet, nature-focused spots in Seoul that visitors say were ‘far better than expected.’
Seonyudo Park — A Calm Island Garden on the Han River
Seonyudo Park was once a water purification plant, now transformed into a unique island where greenery and concrete structures coexist. Many foreign travelers say they are surprised to find such tranquility in the middle of Seoul.
“I had no idea this island park existed. It felt like a quiet green bubble floating in the middle of Seoul.”

Multiple walking paths, riverside viewpoints, and quiet seating areas make this park ideal for those seeking a moment of calm away from crowded tourist zones.
Ichon Hangang Park — A Riverside Space Filled With Local Life
While the Han River parks are widely known, Ichon Hangang Park stands out because it attracts fewer tourists and naturally shows how locals enjoy their daily routines along the river.
“It felt like a place only locals know. No crowds, just people enjoying their day.”

Its simple layout and peaceful atmosphere allow visitors to relax and observe the rhythm of everyday Seoul.

Yangjae Citizens’ Forest is relatively unknown even among locals, which is why foreign travelers often react with genuine surprise when they discover it.

Its well-designed walking trails create a refreshing escape during a busy travel day and offer an experience that feels distinct from more commercialized parks.
Bukhansan Dulle-gil (Easy Trail) — Accessible Nature & the Surprise of Free Hiking
Korean hiking culture is well-known, but attempting a full ascent of Bukhansan can feel overwhelming. The Dulle-gil offers a gentler option—mostly flat forest trails suitable for beginners.
“I thought hiking in Korea would be intense, but the trail was gentle and beautiful.”

Many foreign travelers are surprised to learn that most mountains in Seoul are completely free to access, unlike many countries where national park or trail entry fees are common.
“Hiking is free? In my country this would definitely cost money.”

Achasan Ridge Trail — A Quiet Viewpoint Overlooking the City
Achasan is easy to climb yet widely praised as “one of the most underrated viewpoints in Seoul.”
“The view was incredible, and there were almost no people. I can’t believe this is in Seoul.”
