Gyorae Natural Recreation Forest & Keun Jigeurioreum: A Hidden Summer Hike in Jeju

If you're visiting Jeju in summer and want to escape the heat without missing out on real nature — this is the place. Most people head straight for the open oreum (volcanic hills) like Saebyeol, but without any shade cover, those trails can get brutal under the July and August sun. I keep coming back to Gyorae Natural Recreation Forest (교래자연휴양림) instead, and more specifically, to Keun Jigeurioreum — a forested volcanic hill tucked into Jeju's inland belt between the coast and Hallasan. Even on the hottest days, the dense canopy keeps it so cool it almost feels air-conditioned.

The Trailhead

Right at the entrance, the path forks into the Eco-system Observation Trail and the Oreum Walking Trail. If you're heading for the summit, follow the oreum trail sign. The moment you step into the forest, the temperature drops noticeably — the canopy is so thick that barely any direct sunlight reaches the path below.

One thing worth knowing before you head in: collecting wild plants is strictly prohibited inside the recreation forest. The signs are clear about it, and honestly it makes sense — the ecosystem here is what makes it so alive.

Walking Through Gotjawal — and a Surprising Scent

The trail winds through gotjawal — a type of forest unique to Jeju, formed on rugged lava rock where trees, vines, and ferns grow together in dense, tangled layers. It's one of those places that feels genuinely wild.

Somewhere along the path, a sweet, almost honeyed scent drifts through the air. I kept looking around wondering where it was coming from, and eventually spotted clusters of small white flowers growing along the trailside. It turned out to be privet blossom (쥐똥나무꽃). In spring the privet tree blooms with fragrant white flowers, but come autumn its berries ripen into small, round, jet-black clusters — and yes, the resemblance to mouse droppings is exactly what earned it that name. The fragrance, though, is completely at odds with it. Walking through that stretch with the scent all around me made the whole trail feel lighter somehow.

The Charcoal Kiln Site — How Trees Fight Back

Further along, the trail passes a charcoal kiln site — a spot where trees were cut and burned to make charcoal in the past. The ground around it is covered in ferns now, but what caught my attention were the trees themselves. When a tree is cut down, it doesn't always just die. Instead, it sends up multiple new trunks from the same root system — a last effort to survive. You can see it clearly here: trunks splitting into four or five branches from a single base, growing back in every direction. It's the kind of thing you walk past without noticing unless someone points it out, and then you can't stop seeing it everywhere.

Bat-Leaf Tree Flower

Near the charcoal kiln site I spotted another find: the bat-leaf tree flower (박쥐나무꽃). The tree gets its name from its leaves, which are shaped like bat wings — wide and lobed on each side. The flower itself is a delicate dangling yellow, almost like a little tassel. It's easy to miss if you're just looking ahead on the trail, but once you slow down and start noticing, the forest is full of these small details.

A Wild Roe Deer in the Forest ⭐

This was the moment that made the whole day. I was walking quietly through the gotjawal when a roe deer stepped out from the undergrowth — and we just looked at each other. No fence, no zoo enclosure, no tour group. Just a wild roe deer in a genuinely wild forest. I've had encounters like this in Jeju before and it never gets any less startling. The forest here is deep and undisturbed enough that the wildlife actually lives here. I managed to catch it on video too — worth watching.

The Hinoki Cypress Forest Appears

After the roe deer encounter I kept walking, and then — the forest completely changed. The narrow, tangled gotjawal path suddenly opened up into something else entirely: a stand of enormous Hinoki cypress trees, their trunks shooting straight up with no branches until they're far overhead. The light comes through differently here, the air smells of phytoncide, and the whole atmosphere shifts. I wasn't expecting it at all the first time I came, and that surprise is part of what makes it so memorable. There are large wooden platforms scattered through the cypress grove — perfect for sitting down and actually taking it in.

☀️ Sunny's Tip Pack a lunch and eat it here in the cypress grove on the way back down. Sitting on one of the wooden platforms with phytoncide in the air and complete quiet around you — no restaurant comes close to that. I still think about the lunch I had here that day.

The Climb to the Summit

Past the cypress forest, the real climbing begins. Stone and dirt steps alternate as the trail steepens — it's the only genuinely demanding section of the whole hike. The last 400–500 metres are where you'll actually feel your legs working. Take your time, stop when you need to, and enjoy the green around you rather than rushing.

Along the upper trail, wild raspberries and dark mulberries grow right beside the path. In early summer they're ripe and bright red — a little distraction that makes the climb feel shorter. Just keep in mind that collecting wild plants is not allowed anywhere inside the recreation forest, so leave them as they are.

The Summit Observatory

The summit observatory opens up to a panoramic view of Jeju's inland belt — rolling hills, forest, and on a clear day, Hallasan in the distance. After all that climbing through the enclosed canopy, stepping out to this is genuinely satisfying.

Turn around and look down, and you'll see something unexpected: Jeju Stone Park (돌문화공원) spread out directly below — its entire grounds visible from up here in a way you'd never see from inside it. It's one of those summit moments that feels earned.

Before you head back down, look for the stamp box near the summit — part of Jeju's Premium Forest Trail stamp program. A small ritual that marks the top of the hike.

Getting There

📍 Address Gyorae-ri, Jocheon-eup, Jeju City, Jeju Island
🕖 Hours 09:00 – 18:00 (entry closes 17:00)
💰 Admission Adult ₩1,000 · Teen/Military ₩600 · Under 12 & 65+ free
🚗 Parking Free · spacious lot at the entrance
☀️ Sunny's Tip The forest is well inside Jeju's inland belt, so public transport isn't convenient here. A rental car or taxi is the practical way to get here. If you're renting a car for your Jeju trip anyway, this pairs well with Jeju Stone Park right next door — you can see it from the summit, and visiting both on the same day makes good sense.
📍 Gyorae Natural Recreation Forest
🏠 Gyorae-ri, Jocheon-eup, Jeju City, Jeju Island

If you're in Jeju during the summer and want real nature rather than another beach or tourist site, this is the hike I'd point you toward. A wild roe deer if you're lucky, the scent of privet blossoms through gotjawal forest, Hinoki cypress trees appearing out of nowhere, and a summit view that takes in the entire midland — all for ₩1,000 entry and a couple of hours of walking. Not bad at all. 🌿
