Yeosu City's official tourism page schedules the themed Time-Travel Busker from 10 April to 7 November 2026 on Fridays and Saturdays, 19:30–21:30. This special route does not run Sundays. It combines musical performances, commentary and evening attractions near Yi Sun-sin Square and Soho Dongdong Bridge. Fares are ₩20,000 standard, ₩10,000 for qualifying Yeosu residents, school pupils, seniors, soldiers, national merit recipients and disabled guests, and free for preschool children. Bring proof for eligibility; discounts cannot be combined. This is different from the regular night loop, so check the actual boarding place and chosen date before booking. Tel. 061-692-0900 / 0903.
Service-day warning: The same official page calls Friday and Saturday the standard days (excluding Sunday) yet separately displays 'Mon–Sat during the Island Expo.' It is unclear from the page alone whether this expands the Busker service or describes another night-loop route. The 2026 Yeosu World Island Expo runs 5 September–4 November. During this period, confirm the specific route, available date and boarding point on the booking page or directly with the operator before paying.
