Paddle a sea kayak through Japan's second-largest mangrove tunnel at dawn, gliding silently past fiddler crabs and mudskippers with a naturalist guide.
What to expect
You meet guides at the river mouth as the tide is rising, get a five-minute paddling briefing, then slip into narrow green channels canopied by mangrove roots. Guides point out endemic crabs, herons, and the occasional Ryukyu flying fox overhead. The water is glassy and the only sound is your paddle and birdsong. Trips run about 90 minutes to 2 hours depending on tide.
Good to know
Book the earliest morning slot (tide-dependent, confirm exact time online) to beat both heat and any other visitors; park is a 15-minute taxi from the port. Wear quick-dry clothes — you may get splashed.
