I always see the sky trails of Wuliu Island on social media accounts, which makes me heartbroken. The sea view is amazing, especially the glass floor. If you are planning a trip to Busan, I highly recommend this place to everyone. It is a great place to take pictures and easy to get there. I took a bus from Busan Station to get there. We spent half a day on the five or six islands and then went for a walk on the Igidae beach. The part of the Wuliu Island air trail is very small, there is only a small glass wall on the cliff, the scenery is good, but the distance is very short, it is easy to get there, just use the Kakao map and take a bus from the city. The scenery is cool, although there may be less glare in the morning, and a fun experience. Slippers on the glass are lovely. All activities are free and a coastal walk is highly recommended after the event.
