The Urauchi River, the longest river in Okinawa Prefecture, flows for 24 miles (39 kilometers) through the heart of Iriomote Island’s dense mangroves and subtropical forest, and cascading down two waterfalls, Kanpiuree and Maryudo, along the way.
The most popular way to experience the spectacular scenery along the Urauchi River is on a river cruise. These popular excursions depart frequently throughout the day from the Urauchibashi bus stop and take visitors along a 5-mile (8-kilometer) segment of the river to Gunkan-iwa Rock. From there, it’s possible to trek for 30 minutes through the jungle to a viewing platform overlooking Maryudo Falls.
Alternatively, visitors can rent canoes and paddle their way along the Urauchi River, or take a guided canoe tour with motorized boat transfer upriver.
