Spend moved into the alleys
The avenues are still there, but in 2026 people turn into the lanes. Dosan Park and Cheongdam are one south day: walk the avenue to Dosan, then stop. That day replaces Garosu-gil. Do not also open Seongsu, and do not add Jamsil. If Seongsu is its own day, take the warehouse back streets, the shoe lane and Yeonmujang, then Seoul Forest. The city has pointed to the alley near Gyeongsu Elementary — that is a back-street pattern, not a new landmark, and this map does not pin it. Gwangjang is the centre-axis night meal. Do not open Garosu-gil, Seongsu and Jamsil on the same day.
The Hangang bus: check it the same day
The Hangang bus began service on 18 September 2025. By 13 August 2026 it had about 501,430 boardings. From 15 August 2026 there are extra evening runs: Jamsil to Yeouido at 18:50 and 19:20, Yeouido to Magok at 20:25 and 20:55, plus some afternoon extras. Discharge from Paldang Dam, or high water, cancels runs. East piers — including Jamsil, Ttukseom, Apgujeong, Oksu and Seoul Forest — have been stopped. Check the operator the same day. Magok is the west terminus and is not a place on this map. It is another day, not the Yeouido evening. This site does not print a fare.
Cheonggye A01, weeknights only
From 22 October 2026 the Cheonggyecheon autonomous bus A01 runs on weekdays from 19:00 to 23:50, about every 30 minutes, nine runs. The last departure from Cheonggye Plaza is 23:00. It does not run on weekends or holidays. The route is Cheonggye Plaza, Cheonggye 3-ga / Seun, Cheonggye 5-ga / Gwangjang, about 4.8 km round trip. It is free for now. A later paid fare has been announced as planned — follow that day’s notice. Carry a transit card even while it is free. Capacity is about eight passengers. Reboarding mid-route is not guaranteed.
SEOULDAL only on a Yeouido day
The tethered balloon SEOULDAL is only an add-on on a Yeouido day, not a second viewpoint paired with N Seoul Tower. Dusk still keeps one height: N Seoul Tower or Lotte World Tower, not both.
The five-day skeleton still holds
Day 1 is Jongno palaces and Bukchon. Day 2 is Myeongdong and Cheonggyecheon. Day 3 is Hongdae and Yeonnam, and it can reach the river at Yeouido. Day 4 opens one south line: Dosan and Cheongdam, or the Seongsu back streets, or Jamsil. Day 5 is rain or one museum. This is not a festival calendar.
