Float the Honkawa and approach the Atomic Bomb Dome by SUP on a calm 3 km round-trip that mixes basic paddling with history. Guided instruction, board rental, and a stop at Peace Memorial Park make this an accessible, reflective river outing.
More ways to explore the area's outdoor wonders
You step from a small gangi under an old camphor tree, board damp with morning, and the Honkawa River opens like a slow-moving street through the city. Buildings slide past; the Atomic Bomb Dome waits ahead—silent, visible, a human landmark on the water's edge. The river nudges the board forward; the current and tide decide the pace.
