Korean Mountains Worth the Trip

Foreign visitors to Korea’s national parks are not evenly spread across the country. A small number of mountains draw the overwhelming majority of them, and the ranking is not what most guides assume.

Hallasan, on Jeju, brings in more foreign hikers than any other Korean mountain — a figure well over double the next name on the list. Seoraksan is second, comfortably ahead of everything except Jeju. Bukhansan, inside Seoul’s city limits, is third — no flight or long bus ride required, which is part of why it has become a genuine trend rather than a niche interest among visitors deciding between another palace and a real trail.

That third fact is the more interesting one. Korean and English coverage alike has started describing a shift — visitors choosing a mountain over another neighborhood of cafés — distinct enough to have picked up its own name: K-hiking.

What each guide in this section covers

Not a ranked list. Each mountain gets its own page, because “which trail” and “how do I get there without a car” are different questions on every one of them, and a single shared list flattens exactly the details that decide whether a day trip works.

• Bukhansan — reachable by subway from downtown Seoul, four routes from a short beginner walk to the summit, and what to expect at the entrance villages afterward
• Seoraksan — what the cable car actually reaches, the real routes to Daecheongbong, and the autumn foliage window
• Hallasan — what the reservation actually covers, the two routes that reach the summit, and the two that don’t
• Jirisan — Korea’s first and largest national park, not one of the top three for foreign visitors but the one with the biggest recent change: Chilseon Valley’s 2026 reopening after nearly twenty years of near-total closure
• Songnisan — an inland Chungcheong mountain built around Beopjusa, a UNESCO-listed temple that charged an entry fee for 56 years before it disappeared nationwide in 2023

Each page covers transit, trail options by difficulty, the season that actually matches the photos you have seen, and what to know before you go — not just that the mountain exists.

Two pieces here aren’t about a single mountain at all. If you’re not sure which hike fits you, start with hiking near Seoul, sorted by difficulty — it adds four more mountains (Namsan, Achasan, Gwanaksan, Cheonggyesan) not covered above, and sorts all nine from a 30-minute walk to a two-day ridge traverse. And once you know what you need: Seoul will lend you hiking boots — free — three city-run centers near Bukhansan, Bugaksan and Gwanaksan rent foreign visitors hiking gear at no charge, and it’s a Seoul-only program none of the other mountains above have. And beyond Songnisan’s own Beopjusa: Sansa, Korea’s seven UNESCO mountain monasteries — which of the other six you can actually reach without a car, and which effectively need one.
