The fountain system uses 380 pumps to circulate river water, cleaning it through six layers of filters before spraying it.
Jamsu Bridge was designed to be partially submerged; its height is intentionally low to survive seasonal river level fluctuations.
The Moonlight Rainbow Fountain features over 10,000 LED nozzles that create different color patterns.
During peak summer months, the bridge area hosts frequent street food markets and cultural pop-up events.
The bridge's unique design includes a specific 'pedestrian-only' mode on the lower deck during weekend traffic control periods.
Banpo Bridge is a two-level girder bridge spanning the Han River in Seoul, uniquely integrated with the Moonlight Rainbow Fountain. The fountain system consists of 380 nozzles installed on both sides of the bridge, shooting water directly from the river into the air. It holds the Guinness World Record as the world's longest bridge fountain. During operation, water displays are synchronized with music and colorful LED lighting. The lower deck, known as Jamsu Bridge, is a submerged bridge designed to be occasionally underwater during heavy monsoon flooding, allowing it to act as a pedestrian and bicycle path. The bridge connects the Seocho District on the south to the Yongsan District on the north.

Bring a picnic blanket and some snacks, as most visitors sit on the grass of Banpo Hangang Park to watch the show.
If you are on foot, head to the lower deck (Jamsu Bridge) to see the water curtain up close, but be prepared for mist.
Check the weather forecast, as heavy rain or high wind conditions often result in the cancellation of fountain shows.
Do not attempt to walk on the upper bridge deck; the pedestrian viewing area is strictly on the lower Jamsu Bridge deck or the riverside park.
The fountain operates seasonally from spring through autumn and is typically disabled during winter months for maintenance and safety.
