On any Donghae / Mukho trip, this is one hotspot you can't skip — Course name. Seen from above, it's a Dojaebigol skywalk observatory shaped like a dokkaebi (Korean goblin) club. It's free, and you can stand right above the emerald East Sea waves — a no-brainer addition to your Mukho course. Here's location, hours, the best photo spots, and the Dojaebigol Sky Valley pairing in one place.
What is Haerang Observatory?
Course nameis a sea-side skywalk perched in the Dojaebigol area of Mukhojin-dong, Donghae. The big draw is its dokkaebi-club-shaped design (visible from above). Right across from it is Composition 5 — Nongol Damgil murals + colorful rooftops:— the two together is the classic course. The waves and dark cliffs crash right under your feet, making this the most dynamic ocean view on the whole Mukho course.

Three reasons to visit Haerang Observatory
1. Dokkaebi-club-shaped skywalk
Haerang Observatory's biggest signature is the design that reveals itself from above — a dokkaebi-club shape . 'Dojaebi' is the Gangwon dialect for 'dokkaebi' (Korean goblin), and the design echoes the local Dojaebigol legend. Look down from the Sky Valley and the dokkaebi-club outline really does click into place.
2. Emerald East Sea + dark cliffs
Walk the Haerang Observatory deck and beneath your feet you'll see dark volcanic rocksand emerald wavescrashing against them in striking contrast. It photographs like a painting — in person, it's even more powerful.
3. The colorful 'Haerang' letter sculpture — top of the photo list
Right at the entrance there's a big "Haerang" letter sculpture. The colorful letters + the blue East Sea + the Dojaebigol skywalk all fit in one frame, making this the most popular photo spot on a Mukho trip. The classic shot is sitting inside the empty space of the letters.
💎 Key Points:
Haerang Observatory is free + open long hours (10 AM – 9 PM). It's within a walking distance of Mukho Lighthouse, Dojaebigol Sky Valley, and Nongol Damgil — there's no reason to leave it out of your Mukho course.

💡 TIP: From the top of the skywalk, head out the opposite side and you can walk to filming location — a famous Mukho photo spot..
