Getting there & away
A passenger and vehicle ferry runs between Rohuküla on the mainland and Heltermaa at Hiiumaa's eastern end. Buses from Tallinn via Haapsalu run all the way to Hiiumaa; the ferry crossing is included in the trip. Other buses will drop you off or pick you up at either ferry terminal. It's also common to hitch or ask for lifts off the ferries at either end.
A ferry also connects Hiiumaa and Saaremaa, just 5.5km away.
SLK Ferries(Saaremaa Laevakompanii; 452 4444; www.laevakompanii.ee) runs ferries between Rohuküla and Heltermaa four to six times daily (adult/child/vehicle 45/20/95Kr one way, 1½ hours). Check website for departure times.
Most people don't bother calling ahead, but if you're taking a car and you want to be on the safe side, book ahead, and show up at least 20 minutes before the ferry departs. Have your vehicle registration handy. You can also purchase tickets at either port: Rohuküla ticket office(473 3666) or Heltermaa ticket office (463 1630), a small building on the right as you leave the pier.
SLK Ferriesalso operates a year-round ferry (adult/vehicle 20/75Kr one way, one hour) two to three times daily from Sõru ferry terminal, on the southwesternmost tip of Hiiumaa, to Triigi on Saaremaa.
