There are buses on both islands. Bus timetables are available at the ferry terminals and on the ferry itself. Rishiri has a bike path that circles the whole island. Roads don't go to the interior of either island, so the best way to see them is on foot. There are hiking trails on both islands that really let you explore the best parts of the islands, and it may be desirable to take buses or taxis to the trailheads. Cars are available for rent on Rebun. It is also possible to book a nature tour by bus on the islands.
