Jangan Valley (장안사계곡) is a stream-and-forest valley in Gijang-gun, on the northeast edge of Busan. It lies below Jangansa Temple (장안사), at the foot of Bulgwangsan Mountain, and the Korea Tourism Organization (KTO) describes it as a place for a quiet walk and a rest on a mat under the trees. This guide covers what the sources say about the valley, the temple and the forest trails, how to reach them, and which rules apply.
We checked the sources on 3 October 2026. We have not visited, so this is a source summary and not a review. The KTO photos in this guide show green leaves and have no dates, so they do not show what the valley looks like in autumn or how much water the stream carries.
Quick answer
- The valley is listed as open at all times, with no closing days, and free parking is listed.
- Camping and cooking are banned, according to KTO.
- Visit Busan gives two walk times from the bus stop: 17 and 20 minutes.
What the Valley Is
KTO says the valley sits beneath a temple founded by the monk Wonhyo (원효대사) in the year 673. It says fireflies live in the valley, which is why the street lamps are switched off until the end of July each year. KTO adds that many visitors come because the valley is close to the Jangansa parking lot.
Visit Busan, the city’s official tourism site, describes Jangancheon Stream flowing around Bulgwangsan to form the valley, and says that in summer it fills with people playing in the clear, cool water. A Visit Busan article also mentions a wooden walkway along the stream that leads to the entrance of the temple. Both descriptions are about summer. We found no source on the stream’s water level in other seasons, and the photos here, which show a low, rocky bed, have no dates.
The Rules
KTO says camping and cooking are banned in the valley, to keep the area comfortable. It suggests a simple stay: lay a mat under a tree and rest. We did not find rules on swimming or on bringing food, so check signs on site. KTO says that fireflies are present, which is the reason for the lights-off period each year.
Jangansa Temple (장안사)
Visit Busan says the temple is said to have been founded by Wonhyo and has stood for more than 1,300 years at the foot of Bulgwangsan. It describes the Iljumun Gate and the Four Guardian Kings statues, buildings arranged around a central stone pagoda, and a bamboo forest that is part of the temple’s setting. It says the Daeungjeon Hall and Ungjinjeon Hall are older buildings with wide roofs.
For autumn, Visit Busan’s temple page says the mountain is covered with red autumn leaves and wraps around the temple like a folding screen. That is Visit Busan’s description, and it gives no dates for the best colors. The same page lists the temple as free, open at all times, and equipped with a ramp, an accessible parking lot and an accessible toilet. The listed phone number is +82-51-727-2393.
Forest Trails Next to the Temple
A Visit Busan food-tour article describes a forest trail beside the temple called the Wonhyo Iyagisup Forest (원효이야기숲). It names three routes: the 108 Bunnoe Trail, which passes through a thick bamboo path, the Chamhoeuigil Trail and the Suhaenguigil Trail. It says the forest path leads on to the Bulgwangsan hiking trail. We found no lengths or walking times for these routes, so we give none.
Getting There
Visit Busan gives two descriptions, with different walking times.
- Temple page: get off Village Bus Gijang-gun 9 at the Sangjangan stop and walk 17 minutes.
- Food-tour page: from Exit 1 of Jwacheon Station (좌천역) on the Donghae Line, take bus Gijang-gun 9 from the Donghae Line Jwacheon Station stop, get off at Sangjangan and walk 20 minutes.
So allow 17 to 20 minutes on foot from the stop. We did not find the bus frequency, the ride time or the last bus, so check before you commit to a late return. Our Donghae Line guide covers the line and tickets, and our Busan metro and T-money guide covers the card basics.
Parking is listed as free at the Jangansa parking lot (KTO). The valley’s address is 482 Jangan-ro (장안로 482), Jangan-eup, Gijang-gun. KTO’s listed contact is 051-709-4085.
Eating Nearby
The same Visit Busan food-tour article describes a restaurant called Mansujang Garden at 336 Jangan-ro, with a view of the valley. It lists a whole chicken soup with herbal ingredients and duck cooked on an iron plate, hours of 11:00 to 20:30, and closing days on the second and fourth Tuesday of each month. The listed phone number is +82-51-727-5582. We have not checked the menu, prices or whether the shop is open on a given day, so treat this as a lead and call first. We found no information on allergens, halal or vegetarian options.
First-Timer Tips
These are our suggestions, not sourced facts.
- Bring water and a mat, because KTO suggests a mat and bans cooking.
- Wear shoes that can handle rocky ground near the stream.
- Check the last bus home before you set out.
- Pair the visit with other Gijang sights only after checking the bus routes. We have not verified any link.
