Public transport on Iriomote is rather limited, but most lodges on the island offer free transfers to/from the nearest port, and both Anei and Yaeyama operate free shuttle services timed to meet ferry departures.
On foot
A demanding 20-kilometer trail crosses the island. The southern terminus is over 1 km from the Ohara port, and not labeled well, so a north-to-south passage, beginning with the Urauchi River cruise, is the recommended route. The jungle is home to habu vipers, which though rare, are venomous. After a Japanese hiker went missing in 2003, signs now ask hikers attempting the cross-island hike to submit a proposal to the local police department.
By bus
Iriomote KÅtsÅ« runs 5 services per day in each direction from Shirahama to Funaura 30 min, ¥390, 3 of which continue across the north coast to Ohara on the east from Funaura 50 min, ¥670. Tell the driver where you're going when getting on and pay when you get off. A three-day bus pass is also offered at ¥1000 per person.
