Most visitors to Haeundae head straight for the beach. Blueline Park is a different kind of outing: a stretch of old coastal railway on Busan’s east coast that now carries two separate rides, with a small fishing port and a sea-view lookout along the way. It is easy to mix the two rides up, so this guide sets out what each one is, where it goes, and what to check before you turn up.
Every hour, distance and phone number below comes from a named source, and we note the date it was checked. Where sources disagree or say nothing, we say so instead of guessing.
Our Family Ride: The Beach Train Beside the Sea
We rode the Haeundae Beach Train to Cheongsapo with our children, aged 5 and 3. They liked how close the train ran to the sea and said it felt as though we were travelling over the water. Our notes are about the Beach Train, not a ride in the Sky Capsule.
For another family trip I would check online availability before travelling to the station. Our notes warn about busy weekends, but they do not prove that same-day tickets are always unavailable.
If you bring a stroller, the operator’s current FAQ says it must be folded to board either the Beach Train or the Sky Capsule. That is an operator rule, separate from our ride experience. Blueline Park official FAQ (checked 15 October 2026).
Family notes added 15 October 2026. The visit date was not recorded. The children were aged 5 and 3 at the time.
Where to Go: One Old Railway, Two Different Rides
What Blueline Park is
Haeundae Blueline Park is an eco-friendly redevelopment of the former railroad facilities of the Donghae Nambu Line. The old line ran 4.8 kilometres from Mipo through Cheongsapo to Songjeong. According to the Korea Tourism Organization (KTO), the park forms part of the new core of the Haeundae Tourism Special Zone, an international tourist region in Busan.
Two rides operate along that corridor, and they are not the same thing.
The Beach Train
The Haeundae Beach Train is a sightseeing train. KTO describes it as both a transportation option and a tourist train, running round trip from Mipo to Songjeong via Cheongsapo along the coast of East Busan. If you want to travel the full length of the old line, this is the ride that does it.
The Sky Capsule
The Haeundae Sky Capsule is a four-seat automatic capsule that runs on a 2-kilometre rail, 7 to 10 metres above sea level, along the coast from Mipo to Cheongsapo. It covers only that stretch, not the whole line to Songjeong. If your plan is Mipo to Cheongsapo and you would rather look at the water from above, this is the one.
The two rides are separate, so you can try one or both. We could not find fares or boarding points in the sources we checked, so confirm those before you go (see the list further down).
Daritdol Observatory
Cheongsapo Daritdol Observatory opened on 17 September 2017 in the middle of the closed railroad between Mipo and Songjeong. It is 20 metres above sea level and extends 72.5 metres out toward the sea, between 3 and 11.5 metres wide. A half-moon-shaped transparent floor at the end lets you feel what it is like to walk on the sea. KTO says you can watch the sunrise and sunset from here while looking at Daritdol, a line of five neatly arranged reefs.
Where to Eat: Cheongsapo Port, and a Pufferfish Stop
Cheongsapo Port
Cheongsapo Port lies near the end of Dalmaji Hill, in the direction of Songjeong. Along with Gudeokpo and Mipo, it is one of three ports on the coastline between Haeundae and Songjeong. KTO describes it as famous for beautiful sunrises and as a place where quality seaweed can be found, with fishers crowding the rocks along the shore. The tracks along the shoreline are described as one of only two railroad tracks in Korea situated near the sea.
The area became popular after appearing in a movie, and KTO says many restaurants have since opened selling seafood. Here is the honest limit of our research: the KTO English data we used names no individual restaurant at the port, so we cannot give you a verified name, menu or price for a seafood meal there. Treat the port as a place to walk and look around first, and check current listings for somewhere to eat.
A pufferfish option with a full KTO listing: Halmae Bokguk (í• ë§¤ë³µêµ)
The closest restaurant with a detailed listing in the KTO English data that we found is Halmae Bokguk, at 1 Dalmaji-gil 62beon-gil, Haeundae-gu. It is about 1.9 kilometres from the port in a straight line, so it is not a walk-in stop from the railway, and we have no route information for getting there.
According to KTO, this pufferfish specialist was established in 1986 and is known for bokguk, or bokjiri, a pufferfish soup. Its clean broth and generous pufferfish fillets are what the description highlights, and collagen jelly made from the skin is considered a delicacy. The menu items listed are smooth-back pufferfish clear soup, yellowfin pufferfish clear soup, and a spicy smooth-back pufferfish stew.
Practical details from the listing: open 06:00 to 23:00 all year, 54 seats, non-smoking, no on-site parking. Reservations are taken by phone on +82-51-742-2789, and the general line is +82-51-742-2790. If you have allergies or dietary limits, ask staff about ingredients rather than assuming from the dish name.
Plan Your Visit: A Simple Route
The three places are close together. Measured in a straight line from the coordinates in the KTO data, Cheongsapo Port is about 120 metres from Blueline Park’s Cheongsapo address and about 430 metres from Daritdol Observatory. These are straight-line estimates, not walking distances, so check a map app for the real route.
A workable order, based only on what the sources tell us:
- Start at Mipo, where both rides begin.
- Take the Beach Train or the Sky Capsule toward Cheongsapo. Both rides serve it, but confirm where each one stops with the operator.
- Walk between the port, the park and the observatory.
- Ride back, or continue to Songjeong on the Beach Train.
Which ride to pick comes down to this: choose the Beach Train if you want to reach Songjeong, and the Sky Capsule if you only need the Mipo to Cheongsapo stretch.
Hours, parking and phone numbers
- Blueline Park is open all year round. KTO lists seasonal hours, and for October our editor confirmed a 19:30 closing time (KTO’s listing says 18:30). Parking is available. Information line: +82-51-701-5548.
- Daritdol Observatory is open all year. KTO lists 09:00 to 21:00 in March to May and September to November, 09:00 to 22:00 in June to August, and 09:00 to 20:00 in December to February. Parking costs 300 won for every 10 minutes. Information line: +82-51-749-5720.
- Cheongsapo Port is listed as open 24 hours, with parking available.
These details were checked on 30 September 2026. Confirm the day’s hours by phone, because seasonal schedules change.
First-time visitor tips
- Choose your ride before you arrive. The Beach Train is the only one that reaches Songjeong, while the Sky Capsule stops at Cheongsapo. Our suggestion: if time is short, treat Cheongsapo as the main stop, since the port, the park and the observatory sit within a few hundred metres of one another in a straight line.
- Do not assume lunch is solved. Our sources name no restaurant at the port, and the pufferfish restaurant is well away from the railway. Look at what is open once you are there, rather than planning the meal around the port.
- Phone about the hours. The park’s October closing time differs between sources, and the observatory’s hours change by season. A short call saves a wasted trip.
- Time the observatory to the light. It is described as a place to watch the sunrise and sunset, so our suggestion is to fit it around the sun rather than the middle of the day. Remember it closes earlier from December to February.
- You can skip the pufferfish detour if you want to stay on the railway; it needs separate transport and we have no route for it.
FAQ
Which ride should I take, the Beach Train or the Sky Capsule?
It depends on how far you want to go. The Beach Train runs the whole old line to Songjeong, while the Sky Capsule covers only the stretch from Mipo to Cheongsapo. You can try either or both, because they are separate rides.
Can I walk between the port, the park and the observatory?
They are close together, with straight-line gaps of about 120 and 430 metres. Those are not walking distances, so open a map app for the real route before you set off.
How much do the rides cost?
We could not find fares or boarding points in the sources we checked. Please confirm them with the operator before you go.
What time does Blueline Park close in October?
Sources disagree. KTO’s listing says 18:30, while our editor confirmed 19:30. Call the information line to be sure.
Is there somewhere to eat at Cheongsapo Port?
KTO says many seafood restaurants opened after the area became popular, but its English data names none, so we cannot recommend a specific one. Check current listings on the day.
What we could not confirm: check these before you go
- Fares and boarding points for both rides. The sources we used do not list them.
- The October closing time. KTO’s listing gives 18:30 for October, while the figure we use, 19:30, was confirmed by our editor and is not taken from KTO. Call to be sure.
- How to reach Mipo by public transport. We found no source we could verify, so use a map app.
- A route to Halmae Bokguk from the port, and the exact walking distances between the sights.
- Named seafood restaurants at Cheongsapo Port.
Before You Go
Blueline Park is a half-day idea that does not need much planning: pick a ride, get off at Cheongsapo, walk the port and the observatory, and decide on lunch once you have seen what is open. Check the hours by phone, wear shoes for the walk, and keep the schedule loose enough to stop where the sea view is best.
