Along the coast east of Haeundae Beach, a retired railway line has been turned into one of the most photographed rides in Korea. When I rode it on a clear autumn morning, the red capsule floated silently above the cliffs while the sea stretched unbroken to the horizon.
Haeundae Blueline Park runs two rides on the old Donghae Nambu railway between Mipo, Cheongsapo, and Songjeong: the Sky Capsule, a private four-person pod gliding on an elevated track, and the Beach Train, a retro seaside train that runs the full coastal line. Ride the Sky Capsule one way from Mipo to Cheongsapo, then take the Beach Train back — and book your capsule days ahead, because it sells out.

What are the two rides, exactly?
The park is a 4.8-kilometer redevelopment of the former Donghae Nambu Line, a coastal railway that once connected this stretch of shore. The tracks were rebuilt for sightseeing, and two very different rides now share the corridor.
The Sky Capsule
The Sky Capsule is a small, colorful, fully enclosed pod that runs on an elevated rail 7 to 10 meters above the shoreline. It travels only between Mipo and Cheongsapo, about 2 kilometers, and one direction takes around 30 minutes. Each capsule is private for your group, up to four people, and it moves slowly enough that you can photograph everything without rushing. The red, yellow, green, and blue pods have become the signature image of the park.
The Beach Train
The Beach Train is a retro-styled sightseeing train running at sea level along the full line from Mipo to Songjeong, passing through Cheongsapo. It stops at several stations, including Dalmaji Tunnel, the Haewol Skywalk, Cheongsapo, the Daritdol Skywalk, and Gudeokpo. Seats are unassigned, so you may stand when it is busy, and the train works like a hop-on, hop-off service: you can get off at a station, look around, and board a later train.
| Sky Capsule | Beach Train | |
|---|---|---|
| Route | Mipo to Cheongsapo only | Mipo to Songjeong, full line |
| Height | Elevated, 7 to 10 meters up | Sea level |
| Seating | Private pod, up to 4 people | Open seats, unassigned |
| Ride time | About 30 minutes one way | Varies by how far you ride |
| Pricing | Priced per cabin, not per person | Priced per person, much cheaper |
| Booking | Reserve well ahead | More flexible, often same-day |
| Best for | Couples, families, photos | Relaxed sightseeing, hopping off |

Which direction should you ride?
Ride from Mipo to Cheongsapo. The track runs closer to the sea in that direction, so the East Sea stays in your window for the whole trip; the return leg faces the hillside instead. If you want the elevated views in your photos and the sea-level views on the way back, take the capsule from Mipo and return on the Beach Train. Around sunset the light turns the water gold, which is why the late-afternoon slots sell out first.
Where do you board, and how do you buy tickets?
Mipo Station is the main starting point, close to Haeundae Beach and roughly a 10 to 15 minute walk from Haeundae subway station on Line 2. You choose your boarding station when you reserve the capsule, and you can only board there — double-check the station before you head out.
Tickets are sold on the park's official website and through major English-language travel booking platforms, which is the easier route if you do not read Korean. The official site releases each date in weekly batches a few weeks ahead, and sunset and weekend slots can sell out within days. Buy the capsule in advance; the Beach Train is more forgiving and often available on the day.
On fares: the capsule is priced per cabin, so it costs several tens of thousands of won for the whole pod and gets better value with three or four riders. The Beach Train is priced per person at a small fraction of that. Fares change, so treat this as a rough sense of scale and confirm the current price when you book.
How do you beat the crowds?
Go on a weekday morning if you can. The park is open year-round, and in October it generally runs from morning to early evening, with longer hours in summer. Weekends, Korean public holidays, and the sunset hours are the busiest by far. Arrive before your reserved time: Beach Train boarding closes 10 minutes before departure, and arriving more than 30 minutes late for the capsule can mean no boarding and no refund. If the capsule is sold out, try for same-day leftovers at the station or ride the Beach Train instead — the views are still excellent.
What are the best stops along the way?
Do not just ride through. The stations are the point.
Cheongsapo is the halfway hub and worth the most time. Its name means "blue sand," and the red-and-white twin lighthouses at the harbor are the area's landmark. The Daritdol Observatory is a glass-floored skywalk stretching out over the sea, and the lanes around the station hold seafood restaurants and cafes. This is the best station to hop off the Beach Train, wander, and reboard later.
Songjeong, the eastern end of the line, has a calmer, more local feel and a beach known for surfing. If Haeundae feels too busy, Songjeong is the natural counterweight.
Mipo sits just past Haeundae Beach and is where most visitors start. If you ride the capsule to Cheongsapo and want a free return, the Green Railway — a coastal walking trail that runs parallel to the line — makes a slow, scenic walk back.

FAQ
Can I ride both the Sky Capsule and the Beach Train in one day?
Yes, and that is the most popular way to do it. Ride the Sky Capsule one way from Mipo to Cheongsapo, explore Cheongsapo, then take the Beach Train back toward Mipo or onward to Songjeong. Plan two to three hours for the full combination with a stop in Cheongsapo.
Is the Sky Capsule scary for people who dislike heights?
Usually not. The track is only 7 to 10 meters above the shore, the pod is fully enclosed, and it moves at a slow, steady pace. If tall bridges bother you, the Beach Train at sea level is the safer choice.
How far ahead should I book the Sky Capsule?
As soon as your dates are fixed. Weekend and sunset slots are the first to sell out, sometimes days after release. Weekday morning slots are easier to get, and occasionally available on short notice, but do not count on it.
Can I walk instead of riding back?
Yes. The Green Railway is a free coastal walking trail that follows the old railway corridor parallel to the rides, passing through the same scenery. It is a good return option if you rode the capsule one way to Cheongsapo and want a slower trip back.
Does the park run in the rain?
Usually yes, the rides operate in light rain. Service can be suspended in heavy rain, strong wind, or typhoon conditions, so check the operator's latest updates before going on a stormy day.
