Cheonmasan Observatory Busan opened for a soft launch on June 9, 2026. It is a new multi-floor complex on Cheonmasan Mountain in Seo-gu, featuring a skywalk with a partial glass floor and a rooftop observatory with panoramic views of Busan port, Namhang Bridge, Yeongdo Island, and on clear days, as far as Haeundae. The views are genuinely impressive.
Here is what you need to know before going: there is no car access. Getting there requires a 40-minute uphill walk from the nearest drop-off point. A monorail is scheduled to open in the second half of 2027, but until then, the only way up is on foot. If that sounds manageable, it is a worthwhile addition to a day in this part of Busan. If it does not, the views from the two observatories inside Gamcheon Culture Village — Haneul Maru and Byeolmaru — cover much of the same area with far less effort.

Before You Go
- Check the weather before going. Overcast days reduce the view considerably, and strong wind or rain can close access to the skywalk and rooftop entirely.
- The building is fully open 10:00–17:00, Tuesday through Saturday, excluding public holidays. Arrive with enough time to walk up — if you leave the bus stop at 16:00, you will not make it before closing.
- The facility is free to enter during the soft launch period.
- Full opening, including the cafe floors, is planned for late 2026 once tenant fit-out is complete.
- Monorail opening: planned for July 2027. Once it opens, Cheonmasan Observatory Busan will be significantly more accessible for all visitors.

Getting There
From Busan Station: Take bus Seo-gu 2-2 from the stop opposite Busan Station Plaza — about 17 stops, 30 minutes — to the Gamcheon Culture Village / Busan Education History Museum stop. From there, walk 1.7km uphill (approximately 40 minutes) to the observatory.
By subway: Take Busan Metro Line 1 to Toseong Station, Exit 6. Walk 170 meters to the Busan University Hospital bus stop and take bus Saha 1-1, Seo-gu 2 or Seo-gu 2-2 — about 11 stops — to the same stop. Then walk 1.7km uphill.
By car: Vehicles cannot access the observatory. Use the Gamcheon Culture Village public parking lot (₩100 per 10 minutes, maximum ₩2,400 per day) and walk from there.

The Walk Up
This is the part most guides skip over. The path is well-maintained and paved — it is not a dirt trail — but it is a sustained uphill climb of around 40 minutes at a comfortable pace. We went as a group of three adults and took it slowly; it still required effort. On a hot day, it would be significantly more demanding.

Wear comfortable shoes. Bring water. If you have difficulty with hills or stairs, or if you are traveling with very young children or elderly family members, think carefully before committing to this one. The uphill path is not suitable for strollers or wheelchairs.
The monorail currently under construction will cover a 3km round trip and is expected to open in July 2027. Once that opens, the access problem is solved. Until then, factor the hike into your decision.
What’s Inside
During the current soft launch period, two floors are open:

2nd floor — Eco Experience Hall and Skywalk The second floor has a media art installation running a nature theme — forest imagery and ambient visuals that use the mountain setting as their subject. The Cheonmasan name comes from a local legend that a celestial horse descended here, and the “forest” theme plays on that natural character of the mountain.

The skywalk on this floor is a glass-floored walkway extending over the cliff edge. Parts of the floor are transparent, so you are looking straight down through the glass. If you have a fear of heights, approach carefully — it is real exposure, not just a novelty.
From the second floor, the view already covers a wide sweep: Namhangdaegyo Bridge, the Amidong neighborhood, Yeongdo in the distance. On the day we visited, the sky was overcast and the views were still striking. On a clear day, the range extends to Lotte Department Store in Gwangbok-dong and across to Haeundae.

Rooftop — Observatory and Sculpture The rooftop observatory gives the widest view. Looking one direction: the port, the bridges, the islands. Looking the other: inland Busan extending toward Haeundae and Nam-gu. On a clear day the range stretches as far as Oryukdo Island and Haeundae. A symbolic sculpture called the Cheonma Lovers’ Statue is on the rooftop and serves as a photo spot.
Note: access to the skywalk and rooftop observatory can be restricted in bad weather conditions.
3rd and 4th floors are closed during the soft launch and will open as cafe space once the facility reaches full operation.

How to Plan Your Visit
This observatory makes the most sense as an extension of a Gamcheon Culture Village day rather than a standalone trip. The walk from Gamcheon up to the observatory adds roughly an hour (40 minutes up, walk back down), and the views from the top genuinely go further than what either of Gamcheon’s two observatories offers.
If you have already been to Haneul Maru and Byeolmaru inside Gamcheon Culture Village and still want more elevation and a wider panorama, this is the logical next stop. If the observatories inside Gamcheon were enough, skip the hike.
My honest take: the view from Cheonmasan is excellent. The walk to get there is not trivial. I would recommend photos first — if the panorama looks like something you would make the effort for, go. If not, the Gamcheon observatories give you most of the same view without the climb.

If you have not been to Gamcheon Culture Village yet, that is the better starting point. The village has two viewpoints, an 8-stop itinerary worth following, the BTS mural and the Little Prince sculpture — all without the 40-minute hike. You can read the full Gamcheon Culture Village guide here
And if you decide to add Cheonmasan Observatory Busan afterwards, the path starts from the same bus stop.
When did Cheonmasan Observatory Busan open?
Cheonmasan Complex Observatory opened for a soft launch on June 9, 2026. Full opening, including the cafe floors on the 3rd and 4th floors, is planned for the second half of 2026 once tenant fit-out is complete. During the soft launch, the 2nd floor Eco Experience Hall and skywalk, and the rooftop observatory are open.
Is there an entrance fee for Cheonmasan Observatory?
No. Entry is free during the current soft launch period.
What are the opening hours and closing days?
Cheonmasan Observatory is open 10:00–17:00, Tuesday through Saturday. It is closed on Sundays, Mondays and public holidays. Access to the skywalk and rooftop observatory may also be restricted in bad weather conditions.
How do I get to Cheonmasan Observatory from Busan Station?
Take bus Seo-gu 2-2 from the stop opposite Busan Station Plaza — about 17 stops and 30 minutes — to the Gamcheon Culture Village / Busan Education History Museum stop. From there, walk 1.7km uphill, which takes approximately 40 minutes at a comfortable pace. There is no car access to the observatory itself. A monorail covering a 3km round trip is expected to open in July 2027.
Is the hike to Cheonmasan Observatory difficult?
The path is paved and well-maintained, but it is a sustained uphill climb of about 40 minutes. Three adults walking at a relaxed pace found it required real effort, and on a hot day it would be more demanding. Comfortable shoes and water are essential. The route is not suitable for strollers or wheelchairs, and it may be too difficult for elderly visitors or young children.
What can you see from Cheonmasan Observatory?
From the 2nd floor and rooftop, the view covers Busan port, Namhangdaegyo Bridge, Yeongdo Island, the Amidong neighborhood, and on clear days extends to Oryukdo Island and Haeundae. The rooftop gives a wide panorama with the port in one direction and inland Busan in the other.
Should I visit Cheonmasan Observatory or just go to Gamcheon Culture Village?
If you are already visiting Gamcheon Culture Village and want to go further, Cheonmasan Observatory is worth the extra hour of walking for the wider views. If you have not been to Gamcheon yet, start there — the village has two viewpoints (Haneul Maru and Byeolmaru) that cover much of the same view without the 40-minute hike. The full Gamcheon Culture Village itinerary is available here.
