More ways to explore the area's outdoor wonders
You push off from a low stone quay in Onomichi and the Seto Inland Sea opens around you — islands rising like low, wind-brushed knuckles, bridges stringing them together for cyclists above. The water holds a slow, salty insistence; currents skirt shoals and beckon paddlers toward rocky coves where gulls wheel and small beaches invite a midday break.

Respect tidal channels
Sections like Funaori Seto can have strong currents—listen to your guide, avoid exposed crossings on ebb, and time passages for neap tides if unsure.
Bring sun protection
Reflected light off the water increases UV exposure—use SPF 30+, sunglasses with straps and a brimmed hat that can be secured.
Wear grippy, wet-friendly shoes
Landings may be on pebbled beaches or rocky shores—closed-toe water shoes or sandals with heel straps protect toes and improve footing.
Budget for island transport
Some island visits require mid-day transport fees or pickups—confirm which island you choose and bring cash for any shared vehicle fares.
Quick-dry paddling clothing
Light, fast-drying layers keep you comfortable when exposed to spray and changing sun/wind conditions.
Dry bag (10–20L)
Keeps phone, extra layers and snacks dry during landings and if water splashes into the cockpit.
High SPF sunscreen & lip balm
UV reflection off the water increases exposure—reapply often, especially after lunch.
