It was wonderful, divinely sleepy, relaxing getaway – perfect if you live on Okinawa. We stayed at the Irumote So mentioned by “beeb” below. We paid 7,000 yen each (!) But had a private room with bath, air, meals, not to mention that view. They shuttled us around to/from ferry and rental car place. Also, met lots of friendly people in the shared dining room. We snorkeled and saw a great variety of fish (many more than Okinawa honto). We hiked up to see the waterfalls and cooled off in the river pools. Had delicious “Iriomote Soba” at roadside stand and frozen pineapple on a stick at another (which you pay for in a little box left out by a refrigerator.) I’d say it’s probably worth renting a car. It’s certainly worth a visit.
